[1.] 16/12/1999 03:59 PM {Thread ID: 46} Rainer Froese   Welcome Message   Dear all, Following a suggestion by FishBase users we opened this simple forum to provide a platform for information exchange on anything that has to do with fish. And here is my first request: We are in the process of assigning species to ocean provinces as defined by Longhurst (Longhurst areas). For this purpose we are looking for 'Checklists of Fishes' for the following islands: Sao Pedro e Sao Paulo (=St. Paul's Rock, off Brazil) Fernando de Noronha (off Brazil) Isla Trinidade (off Brazil) San Felix and San Ambrosio (off Chile) San Fernandez (off Chile) Ascension Island (South Atlantic) I. Martin Vaz (South Atlantic) Tristan da Cunha (South Atlantic) Thanks for any help! Rainer Reply from Daniel Pauly 04/01/2000 03:33 PM: There is a list of species of St Paul's rock in: Lubbock, R. and A. Edwards 1981. The fishes of Saint Paul’s Rocks. Journal of Fish Biology. 18: 135-157. (do you want me to send you a photocopy?) Reply from Don 26/12/1999 04:32 AM: Hi Rainer, Regarding isolated oceanic islands the first place to look is Briggs's Marine Zoogeography: St. Pauls Rocks -"no more than an occasional specimen has ever been taken from near St. Paul. Rocks. Its shore fauna should be similar to that of Ascencion..." Fernando de Noronha - Boulenger 1890 described a few fishes: Boulenger, GA 1890. Pisces. In: H.N. Ridley. Notes on the zoology of F.N. J. Linn.Soc.London, Zool. 20: 483. Isla de Trinidade - small collections by Nichols & Murphy (1914), Miranda Ribeiro (1919) and Paiva Carvalho (1950) - but fish fauna still poorly known, Ypiranga Pingo (1957). 5 endemic species on which Briggs casts doubt. Ascension - Briggs has found 54 species of shore fishes Tristan de Cunha - some 16 species

[3.] 21/12/1999 11:04 AM {Thread ID: 48} E. Best   Curd formation in canned salmon   I was wondering if there is any information on curd formation in canned salmon and ways to reduce this occurrence? Thank you Reply from H. Lupin 23/12/1999 01:33 AM: Curd formation in canned fish depends mainly on pre-cooking and drainig of resulting juices (water plus denaturated soluble non-protein nitrogen). If pre-cooking time is short and drainage insufficient further juices will be released during can sterilization yielding curd in the final product.The basic problem is that pre-cooking time is in practice a compromise between curd formation and weight reduction. The higher the pre-cooking time the less the possibility of curd formation, but the lower the yield (in weight terms) of the pre-cooked fish. Therefore people tends to set pre-cooking times in the short side, and this becomes a standard time for processing. However, if there are some changes in the characteristics of the raw material (e.g. increase in the size of the fish, raw material low quality, seasonal influence) Reply from H. Lupin 23/12/1999 01:45 AM: (continues)production of curd in the final product can not be avoided. Reply from H. Lupin 23/12/1999 01:47 AM: No 52 completes the last sentence of No 51. Actually there are ways to prevent curd formation, wishing so. Reply from E.Best 23/12/1999 05:04 PM: H. Lupin replied with precook as being a factor. All the fish that we process has no precook. Also, I discovered that the larger the can size, the less curd was detected, when salmon oil was added to the can, curd increased, if the salmon had been previously frozen and thawed too quickly, curd increased and if the salmon was too fresh (ie just out of rigor) curd was at an increase. I wondered if there was more specific data to establish protocols that will help reduce this occurrence in the future. I had heard of one person on the West Coast who had done some studies on this. I think his name is Mr. Weikell, or Weidell? Hope you can help me out on this one. I am curious. Also, I will be testing particular theories during the salmon season in 2000. Would you care for the results of these tests? It will include digital photographs and I will be sharing the information with the NFPA as well. Thanks again.

[4.] 22/12/1999 04:14 AM {Thread ID: 49} Dillen Alain   Fluctuating asymmetry in Gudgeon   Does anyone have information about fluctuating asymmetry in fishes, more particularly in the Gudgeon (Gobio gobio)? I also would like information about the 'DeLury'method. It's a depletion method, in which one tries to catch as many fishes as possible In each catch, the fishes are kept apart and are not released until the end of the last catch. This method leads to a depletion of the population number, which means that the number of fishes caught in each catch will decrease. This makes it possible to make a linear regression between number of fishes caught in each catch (Y-axis) and accumulated number of fishes caught in the previous catches (X-axis). Like this, one can make a population estimate by calculating the intercept with the X-axis. My question is : When one makes this estimate, how can he calculate the 95% confidence interval ? I haven't found any work in which this has been done. Regards, Alain Reply from Daniel Pauly 05/01/2000 08:37 AM: Concerning the De Lury method: I think the reason why a method for computing confidence intervals missing is that unexploited population size is estimated as a ratio (intercept on the x-axis), and there are no good parametric methods for estimating the confidence interval of ratios. Moreover, the points of the linear regression are not independent at all .

In this case, the amount of gas in that bladder will be excerting a pressure exactly equal to the surrounding (water) pressure. The only cases where this finely tuned system is out of whack is when fish are quickly brought toward the surface (e.g. in a fishing net), in which case the gas bladder (if any) expands faster than the fish can extract the gas from its bladder (i.e., the fish 'explodes'). Hope this reaches you in time for your report.

These rivers are tributaries of the Amazon. Thanks in advance for any help. Cornelia Reply from Sven O Kullander 17/01/2000 03:08 AM: Preñadilla ("little pregnant", why?) is the local Ecuadorian name for Astroblepus cyclopium, and probably other Astroblepus species (family Astroblepidae) characteristic of high altitude streams of Peru, Ecuador and Colombia. For what little I know of astroblepids, species identification will take a specialist or a systematic revision of the family. In a lecture 1827-28, Alexander von Humboldt describes how preñadillas are washed down the mountains with landslides on volcanic slopes, to the locals more looking like the fishes coming out of the volcano itself (http://gutenberg.aol.de/anonymus/universm/univ041.htm).

I've been given this conflicting information by people (marine biologists/scientists) who SHOULD know. I've felt morays (and no yellow slime has rubbed off) and I've seen injured morays (with no blue skin showing), so I'm inclined to say they're green. Please help me find a written source to settle this issue. Thanks!! Dave Reply from Jack 21/01/2000 12:00 AM: I collected a green moray in Puerto Rico and prepared it as I do for a tank photo. I always wipe off excess mucus because it often gets whitish and ruins the photo. The mucus I wiped off the moray was definitely yellow and when it was all off, the eel was dark bluish gray in color. So I have a question about the green moray. I see the green underwater but when I take UW photos, the slides come out brownish yellow - one has to imagine a faint greenish tinge at best. This has happened every time I try to photograph this species. I use Kodachrome 64 which is usually very faithful in recording color accurately, so what is the explanation?

Reply from Rainer 04/02/2000 06:04 PM: The relationship of the rainbow trout with Pacific salmons was the reason for the change from Salmo to Oncorhynchus. See Smith, G.R. and R.F. Stearly 1989, Ref. 13063. Reply from Don McAllister 06/02/2000 05:13 PM: Hi Helen, This is just a preliminary reply. Hopefully someone will have responded in more detail. Formerly the Atlantic salmon, brown trout, rainbow trout, cutthroat trout and other more geographically restricted species were placed in the genus Salmo, distinct from the 5 principal Pacific salmons which were placed in the genus Oncorhynchus. Vadim Vladkov recognized that the Pacific drainage Salmo - rainbow and cutthroat trouts were more closely related to one another than to the Atlantic basin Salmos, and he separated them in different subgenera. That was followed up by research by Gerald Smith at the University of Michigan. His study convinced him that the Pacific Salmo were actually closest to the Pacific salmons and included them in the same genus, Oncorhynchus. I hope that answers your question. You will have observed: a) that common names do not always indicate relationships b) that scientific names change as we better learn relationships between species. This kind of research, advancing knowledge of what are distinct species, discovering new ones and tracking down relationships using clues sometimes million of years old, is called taxonomy or biosystematics.

But; T. carolinus is rich in saturates (±50% of total lipids) which are conducive to raising LDL-cholesterol (the "bad" cholesterol) levels in humans. For comparison, in cod the ratio of saturates to unsaturates is roughly 20:80, so that this lean fish would rank as "healthier" with respect to its lipid composition

Reply from Afonso Marques 29/02/2000 09:13 AM: Your question doesn't allow a yes or no answer, because some species of "eels" have scales, some species don't. The Anguiliformes may have reduced or no scales at all. For example, the families Anguillidae, the common eel and Synaphobranchidae, Kaup's eel,have patches of little scales all over their body, but for instance other "eels" like those of the families Muraenidae, the moray eels, Congridae,the conger eels, Serivomeridae, Nemichthyidae, Nettastomatidae, Xenocongridae doesn't have any scales at all.

Species- Monocentris Japonica Class- Actinopterygii Order- Beryciformes Family Monocentridae Reply from Michele 06/03/2000 06:58 AM: you should be able to find the Kingdom and Phylum in your biology textbook. Kingdom is the highest ranking, and there are only 5 to choose from (Monera, Fungi, Animalia, Protista or Plantae). There are many more Phyla, but as a hint, fish, reptiles, amphibians, birds and mammals are all in the same Phylum (try searching the web for phylum). You already have the Genus. The scientific name always consists of the Genus, listed first, followed by the species. So the Genus for Monocentris japonica, is Monocentris and the species is japonica. Good luck!

[67.] 09/03/2000 09:30 PM {Thread ID: 168} MMSELDON   Conference on trouts   INTERNATIONAL WILD TROUT SYMPOSIUM, WT-VII, October 1-4, 2,000 Old Faithful Lodge, Yellowstone National Park, Wyoming - Save the Date. Working professional wild trout biologists and fishery conservationists will join with international guests and speakers to attend the seventh International Wild Trout Symposium to be held October 1-4, 2,000 at Old Faithful Lodge, Yellowstone National Park, Wyoming. The Call for Papers has been made. Initiated in 1974, these events are held to provide a knowledge of the critical issues facing wild trout. The objectives of Wild Trout VII are to raise the public awareness of wild trout, their social and economic value, to examine their future in a society with increases in urbanization and decreases in funds, and to evaluate strategies for restoration and protection. Wild Trout Symposia are cosponsored by the U.S. Fish and Wildlife Service, National Biological Service, Bureau of Land Management, U.S. Forest Service, Trout & Salmon Foundation, National Park Service, American Fisheries Society, Environmental Protection Agency, Trout Unlimited, and the Federation of Fly Fishers. The Symposium includes an opening plenary session, two and half days of presentations of papers and poster papers, two luncheons, a banquet, a barbecue, and an exhibit hall. Proceedings of the Symposium are included in the registration cost. In the 25 years since Wild Trout I, drastic changes have taken place in the management, protection and enhancement of wild trout resources. Concepts such as ecosystem management, conservation biology, and the Endangered Species Act have mingled, sometimes uncomfortably, with traditional trout management approaches. At the same time, interest groups have sought much more say in how public resources are managed. Wild trout management in the 21st century will almost certainly mean increasing controversy because of a diversity of public and professional values. The theme of Wild Trout VII, "Wild Trout Management in the New Millennium, are we ready?", was selected to directly confront some of these striking issues. Areas being addressed include: wild trout regulations in the new millennium, ecosystem management, electrofishing injury to salmonids, and threats and opportunities for wild/native trout populations. Panel discussions are being organized to dissect subjects such as: The Endangered Species Act and Limited Entry Trout Fisheries. Attendance at WT-VII offers a unique forum for attendees that is an important learning experience and an opportunity to meet and communicate with the key wild trout conservationists, managers, and scientists in an informal, friendly setting that would otherwise not possible. Additional details on WT-VII and the Call for Papers, are available at the Conference Web Site at: http://www.montana.com/wildtrout Registration and accommodations will be available through the Old Faithful Lodge Service Company: AMFAC Parks and Resorts, P.O.

[87.] 22/03/2000 12:38 PM {Thread ID: 203} Wolfbone   growth (or lack of) of my coyrdaoras   I've had my corydoras (named Hank Rearden) for 3 months now and he hasn't grown a millimeter. Is this normal?? Could someone tell me what I can do to help him? I did some research and discovered that corys are nocturnal so I've been feeding him just before I go to bed. He seems happier, but he still isn't growing. I feed him shrimp pellets and tetra flakes (I have tetras too). The tank is kept at a temperature between 80 and 84 F and a pH level around 7.2. Are these not proper conditions to keep my little Hank in?? Reply from Michelle Hopper 29/03/2000 12:25 PM: Corydoras grow relatively slow, it depends on how large your tank is, the type of fisltration, the genetics of the fish itself and it's feeding aggression as to how quickly it will grow. I have had my cordoras for years and u don't notice the growth of them very much. Also they never get very big. Reply from Michelle Hopper 29/03/2000 12:28 PM: I forgot to mention that your temperature is a little high as well as they prefer about 78F. Too high for too long can lead to stress.

[89.] 22/03/2000 12:38 PM {Thread ID: 206} Wolfbone   Mollies and brackish water   I have a black molly and a silver lyre-tail molly that I keep in my freshwater aquarium. Since I've had them I've been doing research on the Internet and have found in several places people saying that mollies, particularly black mollies, prefer brackish water. Is this true? I never thought that mollies needed salt and I can't put any in my aquarium because I have many other kinds of fish that are freshwater fish. Will my mollies be ok? Reply from Michelle Hopper 29/03/2000 12:18 PM: It is very true that mollies prefer salt in their water. In fact many marine aquarists use them to set up a new saltwater system and live very well in that type of environment. The freshwater fish, with the exception of scaleless fish, can handle salt in their water, (aquarium salt not table salt) of about 1 tablespoon per 5 gallons. This helps keep down alot of bacteria and parisites that can lead to illness as well as keep the chance of infections down. The salt should be replaced when doing water changes but not when just adding water due to evaporation as salt does not evaporate. Many illnesses can also be treated with salt instead of medications which can have side effects.

[90.] 22/03/2000 12:38 PM {Thread ID: 207} Wolfbone   Corydoras and Yo-yo Loach   I think that my Yo-yo Loach (aka Reticulated Loach) is attacking my Corydoras, but every source I can find says that loaches are very docile and that if it appears that they are attacking, they are really only trying to be social. But don't loaches have spines on their noses? So if he's bumping into the cory, he must be hurting him, right? I've noticed that a piece of the cory's dorsal fin is gone and a bit of the "whiskers" on his nose. The loach seems to be leaving the other fish alone, so should I put the cory in another tank? Earlier I posted a message about my cory's lack of growth. I'm thinking this may have something to do with it...? Reply from Michelle Hopper 29/03/2000 12:12 PM: It is always possible for any animal to have a personality clash with another and fish are no exception. Even if the loach isn't hurting the cory the stress of being chased will lower it's immune system thereby leaving it more suseptible to illness. It may be adviseable to seperate them for this reason. I am unsure of whether or not loaches have the barb or spine u were referring to but in any case the harassing my become a problem. Stress wil also cause the fish to not eat as much and expend more energy which may account for the lack of growth.

In the Species Summary you will see water parameters. My German aquarium book says that they are agressive among each other and should be kept solitary. Also, they need freshwater, not brackish water.

In the Gulf region a unique relationship exists between the oil and gas industry, user groups, researchers and managers. Now numbering in the neighborhood of 4,000 structures, petroleum platforms play a role as artificial reefs and also directly impact fisheries through enhancement of productivity, as attraction devices, and as a mechanism allowing dispersal of species across the Gulf. It is the goal of this conference to bring together widely ranging research topics on fisheries biology and ecology of the Gulf of Mexico with examine the relationship between fisheries and the oil and gas industry in the Gulf and worldwide. The proceedings from this workshop will become an important reference for the current state of knowledge for many aspects of fisheries and outer continental shelf development.

Maybe I should be asking for the best online resource for salmonid issues. thanks in advance.

The idea that is behind the box is to mix gravel and eggs in the box and place in a spawning area. If you can find information on this egg box you can get the answer on gravel size.

If I remember correctly the name of it was a paddlebill fish. I wanted to know why this fish has this shape for its bill. I understand that all things evolve but what purpose does this serve for this fish. Reply from Rainer 23/04/2000 10:38 PM: The fish you saw was probably Polyodon spathula, the Mississippi paddlefish. I did not find a reference, but I assume that the paddle-like snout helps to channel plankton towards the wide open mouth, where it is filtered out by the gill rakers.

Reply from Rainer 23/04/2000 10:04 PM: Assuming that your Blue Gills are bluegills (Lepomis macrochirus), adults feed upon snails, small crayfish, insects, worms and small minnows. Young feed on crustaceans, insects and worms. Thus, it may depend upon the size of your goldfish.

[147.] 23/04/2000 10:29 AM {Thread ID: 304} Tony Hill   What were the BIG, tuna-like fish in Cancun Inlet?   It happened the last time I was Cancun. Let me tell you the story... I was fishing in Cancun inlet, which goes between the lagoon and the ocean. Rocky shoreline, deep water, and a strong current. Estimated 70' deep water in the center. I had done very well so far and was feeling good. I had already caught and released some big 'Cudas, Jack Crevalles, and some smaller jacks. Then these torpedos went through. About four feet long, shaped like a football, and FAST, always moving. They looked to be about 70lbs, my best guess. I KNOW that tuna are offshore fish, but that is exactly what they look like. They were light colored, like a yellow tuna. Within a mile or two of where I was, is the edge of the reef where the water drops to 600' or so. I spent days trying to get one. But I usually never even got a bait close to them before they were gone. But on my last day there, I finally got one to take my lure by accident. I had been catching lizardfish for fun when they just happened to go by. I just saw one of their gills flare for an instant, and that was it. I didn't realize that I had him on the line until the drag started screaming. And I mean a sound you don't normally hear from an inshore reel! It was a helpless feeling. The fish never slowed down, never shook it's head, never did anything but go straight like a laser beam. Like hooking a car. As if it didn't know it was hooked. So, let me ask, What do you think they were? I had caught jack crevalles up to 30 pounds or so, while there, and these were very different. No head shaking at all. Just smooth, raw, power, on the end of my line for 300 yards in a straight line, for perhaps 15-20 seconds, and then it was over. Did I mention FAST? Albacore? Yellowfin? Bonito? What do you think?

I h i have 5 little shelldwellers which were sold to me as Lamp. kungweensis. I am unsure if I actually received lamp kungweensis or if they are some other species instead. I suspect possibly L. meeli. The reason for my suspicion is confusion between the Ad Konings picture of a female kungweensis, and the female fish in my tank. Are Lamp kungweensis sexually dimorphic or do females look similar to the males. I have had 2 spawns and none of the fish look like Koning's kungweensis, and males and females are difficult to distinguish. I have taken several pictures of my fish and posted them on my webpage at http://budbud.dhs.org/%7Echelle/shellpics.html additional information about my fish are on http://budbud.dhs.org/%7Echelle/shell.html I have had suggested that these fish may be L. hecqui but I am skeptical because only one picture i have found labelled hecqui looks like my fish, and i suspect that picture to be mis-labelled.

Also, reef-associated fishes have larger brains than, e.g., deep-sea fishes. You can rank the species you mentioned by maximum length reached. Body size is a powerful predictor of many biological characteristics, such as longevity, age at first maturity, natural mortality, etc.

From what I've read, Queens are rather boistrous. If I start with smaller fish and add the queen last can I achieve a peaceful community and have my queen too? Any particular fish I should avoid? Reply from Javier 24/05/2000 07:33 PM: Hey Michael, That's a great size aquarium. I have a friend that has the same size aquarium, and he has a french angel, a harlequin tusk, 2 dogface puffers, a king angel, a filefish, and a blueface angel. He has never had any problems with them fighting. The size of the queen that he introduced was 3-1/2 to 4 inches and it was the 3rd fish that he added to the tank. Yes, tipically your most agressive fish goes in last. Of course, to my experience, it's also dependant on the individual fish. Don't forget to quarantine the queen first. Hope this helps...

This extremely beautiful golden (hence dorado (and Danish "guldmakrel" lit. goldmackerel)) fish is adept at catching flying fish, cruising below them, as they attempt to "fly" to safety. Fishbase has pictures of the fish, but a good photograph of a live fish will do its vivid colours more justice. As it is a common sportfish, you should be able to find it in most fishbooks.

Reply from Thorke 29/05/2000 05:31 AM: The coast of Norway is very rich in fish, especially in the northern part. The most common shorecaught species are coalfish and cod, with some nice pollack to the south and mackerel in the summer. A small boat, or a booked trip with a bigger one, will give you the opportunity to catch really big fish, including the previous mentioned species and ling, torsk, wolffish, haddock, norway haddock and even the giant halibut! Deep water fishing in the south produce giant ling and torsk along with blue ling, white skate, greenland shark and velvetbelly shark. There is also chance to catch a big variety of smaller species. In freshwater there is good trout fishing in inland lakes as well as stream fishing for trout and salmon. The salmon fishing is severely overpriced compared with the quality (still thriving on the glory of times gone by). Finland produce very big grayling in lakes and streams in the north, as well as pike and perch fishing in the south and from the coast (the Baltic Sea is brackish). Other possible catches include seatrout and whitefish. If you have further questions you are welcome to e-mail me and ask, especially about the Norwegiean coast/sea (or Denmark).

I commonly see them in the trade, and I have kept them before. The fish you are talking about is Gobioides broussonnetti. It is a type of brackish water goby. It is actualy found in the US. It can be found in the southeast around the gulf. It can get 63cm(25in) long. I fed mine frozen brine shrimp and blood worms. When I kept mine I kept it on sand, and it would always dig a burrow under a rock and it would spend most of its day in his little cave. When I turned on the lights at night he was always out, so I would feed him right before I turned out the lights. Just to make sure that this is the right fish here is a picture of it: http://www.fishaholics.net/gallery/gobioides_broussonnetii.html The other "Dragon Fish" you spoke of is Scleropages formosus, its common name is the Asian Arowana. It is on the CITIES II list I believe. They are currently illegal to sell in the US, but if you did find one the price would be some where around $750-$10,000 USD.

SO: J.-FISH-BIOL. 1990 vol. 36, no. 6, pp. 883-902 LA: English AB: A review is made of the literature on the back-calculation of fish body length from marks on scales or other hard parts (otoliths, vertebrae, fin rays, etc.). Though the technique is widely used it does not appear to be well understood. Regression methods are commonly used, apparently in ignorance of the more realistic proportional methods. It is not generally recognized that there are two equally plausible back-calculation hypotheses which can lead to significantly different back-calculated lengths. The Fraser-Lee equation, the most commonly used back-calculated formula, follows neither of these hypotheses but is based on a misuse of linear regression. It is recommended that back-calculation be restricted to procedures following one of the proportional hypotheses; that the difference between lengths calculated using the two hypotheses is a useful measure of the minimum uncertainty in back-calculation lengths; and that more attention be paid to validating back-calculation hypotheses by comparing observed and back-calculated lengths for individual fish. The pattern of heteroscedasticity in body length-scale radius plots is noted as a useful diagnostic in evaluating back-calculation hypothesis. (DBO) note: if you think this might help, send me a mail and i'll try to have it posted to you Reply from H. R. Kristiansen 10/07/2000 01:10 AM: I went to a scientific expedition with Prof. Kazakov from Sct. Petersburg. We caught lake salmon in the Piscajokki river system and I used the socalled proportional method to back-calculate length at age og a number of lake salmon. I can provide you with this information and some theoretical considerations as well. When scale growth is proportional to body growth (length), the proportional method is certainly the best, because it considers the scale size of each individual and takes into account that very juvenile fish are born without scales.

(Range of prey lengths the fish could give corresonding to its mouth size) Thank you very much Reply from F. Zancada (Spain) 13/08/2000 09:09 AM: As an angler used to spinning, I have noticed that even small trout measuring barely 5 to 7 cm can bite and get hooked in devices carrying 3 cm spoons, whose total lenght is 5 cm. Ironically, I started this fishing fashion because I was told it was the way to catch big trout and avoid the small size.

I remember TFH Press having published one but I can't recall the year when it was published. I suppose its out of print. Reply from Sven 19/06/2000 11:39 PM: Much has changed since the publication of Martin Brittan's Rasbora revision in 1954, reprinted by TFH as: Brittan, R. [1972]. Rasbora.

Technol., Manila 3: 1-224. Thus there is no single "best" reference. Rasbora is not a monophyletic or natural group, but a catch-all of small fishes. Kottelat & Witte recently placed Rasbora axelrodi in a new genus Sundadanio as a danionin; the popular aquarium fish, Rasbora heteromorpha was transferred by them to the genus Trigonostigma along with the similar "ex-Rasboras" T. espei, T. hengeli and T. somphongsi.

Reply from Benjamin Vallejo 22/06/2000 08:29 PM: Swordtails and Platy fish first begin to breed 30-45 days after birth. This is according to breeders. Peter Scott writes in his book "Livebearing Fishes" that after the frist breeding, fry are born roughly every month. I reckon that breeding is likely temperature dependent with smaller species tending to breed more frequently than larger ones. Not surprisngly, fish breeders keep this a secret!

From what I have read P. hystrix is one of the larger freshwater rays, because of this it demands a larger tank than a 55gallon aquarium. I have friends who have successfuly kept P. hystrix in a 180gallon aquarium. A 125 gallon aquarium tank might work, but if I were you I would check the disc diameter of P. hystrix before trying it. I have also read that P. hystrix is more sensitive to water conditions than other rays. I have kept P. motoro before in a 125 aquarium. I found out the hard way that rays are VERY sensitive, I did a water change that was too large(about 50%) and wiped out some bacteria, the next day the ammonia went up very slightly and my ray died. Don't get me wrong though rays are a very fun fish to keep, they have a lot of personality, you can train them to eat from your hands. I would reccomend reading up on P. hystrix before getting a ray though.

Trachichthyidae (Slimeheads) picture (Hoatl_u0.jpg) by SeaFIC Map Order: Beryciformes (sawbellies) Class: Actinopterygii (ray-finned fishes) FishBase name: Orange roughy Max. size: 75.0 cm TL (male/unsexed; Ref. 36696); max. published weight: 7,000 g (Ref. 36697); max. reported age: 149 years Environment: bathypelagic; oceanodromous (Ref. 51243); marine; depth range 180 – 1809 m Climate: deep-water; 3 – 9°C; 65°N - 56°S, 180°W - 180°E Importance: fisheries: highly commercial Resilience: Very low, minimum population doubling time more than 14 years(K=0.04-0.06; tm=5-32; tmax=130; Fec=10,000) Distribution: Gazetteer Western Atlantic: Gulf of Maine (Ref. 4784) [in error according to Moore (Fishes of the Gulf of Maine, in press), should be off northern Nova Scotia]. Eastern Atlantic: Iceland to Morocco; Walvis Bay, Namibia to off Durban, South Africa. Indo-Pacific: south-central Indian Ocean and New Zealand. Eastern Pacific: Chile (Ref. 27363). Several stocks may exist as suggested by distinct spawning sites and seasons. Morphology: Dorsal spines (total): 4 - 6; Dorsal soft rays (total): 15 – 19; Anal spines: 3; Anal soft rays: 10 – 12. Bright brick-red in color, mouth and gill cavity bluish black (Ref. 4181). Ventral scutes: 19-25. Biology: Inhabits deep, cold waters over steep continental slopes, ocean ridges and sea-mounts. Shallow range of usual occurrence from Ref. 27121. Appears to be dispersed over both rough bottoms and steep, rough grounds where it feeds on crustaceans and fish. In New Zealand, the main prey include mesopelagic and benthopelagic prawns, fish, and squid, with other organisms such as mysids, amphipods and euphausiids occasionally being important (Ref. 9072). Juveniles feed mainly on crustaceans (Ref. 27075, 27076). Grows very slowly and is one of the longest lived fish species known. Based on parasite and trace-element analyses, orange roughy is a sedentary species with little movement between fish-management zones (Ref. 27089). Little is known of the larvae and juveniles which are probably confined to deep water (Ref. 27088). The fishery targets sporadically formed dense spawning and non-spawning aggregations. Marketed fresh and frozen; eaten steamed, fried, microwaved and baked (Ref. 9988). Red List Status: Not in IUCN Red List (Ref. 53964) Dangerous: harmless

Essentially, any fishing you do on one species will impact on the others (thought bycatch, and trophic interactions). The only way this can be really addressed is through a dynamic ecosystem model. Such models (e.g. of a lake) are now relatively easy to construct (see information and free software on www.ecopath.org).

Recently my husband and a friend went out on a fishing trip and came across something neither of them had seen before. They think they seemed to be clusters of some sort of jelly-like eggs. The clusters were spherical in shape and ranged from the size of a cantelope to the size of a basketball. They were floating separately, mostly submerged. The boat had hit one and a blood tinged substance spilled out. My husband then pulled up beside one and touched it with his finger, he said they were a slimy texture, but that they gave just a little under slight pressure. I think my husband said they made him think of a brain - size & texture wise - I am not sure of the color. Apparently the "egg sacs" were near shore & some of them may have been attached to low hanging branches that had dipped into the water. They were fishing in some of the back waters of the Mississippi, near Keithsburg, IL. We are both fairly familiar with the fauna of the area but we're all stumped. We've asked many friends and aquaintences & no one has any idea what they could've been. I you have any ideas as to what these may have been, or if you know someone who might, we'd greatly appreciate your input. Thank you so much for your time. Sincerely, Joyce & Cole B. IL

For example - how does one "verify" a 250 year old record as claimed? Further, graphs and figures included no ref as to their origin and no statistical treatment - leading one to wonder at its scientific (vs. casual) significance. Finally, the critical questions were not directly addressed - one was expected to derive from graphs that chnage in diversity had/was indeed taking place and was a problem.

Sheffield   Strange Fish   I recently went on a fishing trip in the Gulf of Mexico, while we were fishing our boat was approached by four strange fish that nobody on board had ever seen before. They followed behind the boat as we drifted but would not take a bait. The biggest was about 26 inches in length, very narrow maybe 4 inches wide and 12 inches tall. They were brown and gray in color with slope like faces and puckered lips and they had big humps on their head. I have done some research but as of yet have found nothing. The closest i have come to describing them would be somewhere between file fish and box fish. Any ideas??

It is indeed true, and it is a very cruel process. I am told that over 2/3 of the fish die within the first 3 months of being injected with the dye. After about 3 months, if the fish survives, the color will fade away and be gone. I have seen all of the following fish painted: Indian Glass fish, White Skrit Tetras, Botia Loaches, and even Oscars. Please do not buy the painted fish, it is supporting the killing of innocent fish.

Other catfish species found in Sri Lanka are Macrones vittatus, M. kelatius, M. guilio (Family Bagridae), Wallago attu, Ompok bimaculatus (Family Siluridae) and Heteropneustes fossilis (Heteropneustidae). Nobody has fo far attempted to breed any of these species in captivity. Perhaps you can attempt the methodologies developed for African catfish. I suggest that you contact Dr. Mangalika Hettiarachchi, Department of Zoology, University of Kelaniya for further details.

Note, however, that these numbers are probably biased towards herbivorous fish which we have covered better, and that thus their percentage within all 25,000 species of fish will probably be much smaller.

[307.] 13/08/2000 09:12 AM {Thread ID: 609} F. Zancada (Spain)   Asking about trout   In my region we call "common trout" and "indigenous trout" to a trout having a nice green-brownish and black speckled upper zone and with red dots in the flanks and a white-amber lower part that I think must be the well known "brown trout" or "salmo trutta fario". But our local fish farms grow another kind of trout the locals call "german trout", which are very similar but somewhat darker, more markedly black-speckled and with a definitely grayish hue instead of the green-brown one of the former (when fishing, it permits you see them easier against the greenish background in the watercourses). Their red spots, being less noticeable and numerous, have also an orange tonality rather than the bright red one in brown trout. Can anyone tell me which could be the scientific name of that species of "german" trout? Reply from Kyle Bouchard 14/09/2000 11:56 PM: I believe your local terminology may be confusing things. I am not a biologist, but I am a fisheries research assistant and an avid trout angler. The "German Trout" you are describing is likely the German Brown trout introduced into the US. As far as I know, there is no other trout in the US that resembles it. The differences in appearance you have observed may well be only variations of the same species, or offspring of the German Brown and Rainbow or other trout crossbreeds. Also trout from hatcheries can take on very different characteristics from wild stock. There are no Brown Trout originating in the US that I am aware of .

Reply from Thorke 18/08/2000 07:59 AM: Angling (sportfishing) in Ireland is easily accessible for anyone. For trout fishing you'll need a licence, as well as a permit for most streams and some lakes. The Irish Tourist Board (Bord Fáilte) has some very nice brochures, be sure to get the "Angling Ireland - Salmon, sea trout, brown trout"-map. It's very good.

Hassan   GIS Database for Fisheries   Dear Fish Folks, I am proposing a PhD study on Geographical Information System [GIS] having integrated database for fisheries management in Malaysia. The rational of this comprehensive integrated Geographical Information System is to handle and integrate the large sets of information on fish and its environment so as to develop into GIS and GIS modeling systems, which suit for monitoring fish, fisheries and their complex marine environment. Thus, I would like if anyone could send, suggest printed papers or point anyone who is doing such research so we can exchange views and ideas which would be helpful for our outreach mission i.e. sustainable fisheries.

My Gr. 10 Art teacher just gave us a very difficult assignment: Read a wordy description (of what I believe is a fish) and draw a picture of it. Not surprisingly, I'm finding it very difficult to draw this, and I was hoping that one of you may recognize from the description what type of fish it is. That would be incredibly helpful. So, if you can, NAME THAT FISH! Description: Size small medium, 12-27 inches; slight or no neck; anal entire; ventrals short, caudals in single series; scales small with length and width about equal, smooth, in rows 35-45 or more; rudimentary hind legs present (more evidence in males); tail very short, blunt, rounded, and ending in large rounded plate not prehensile; large shield on top of head; scales on chin between lower labials small; snout short and broad; rostral large, broad; 1-2 loreals; eye small with vertical pupil; eye rests on upper labials; maxillary and mandibular teeth in graduated series. Color: above pale tan to dark brown or drab, frequently with yellowish, greenish, or bluish tinge, sides olive brown, and the belly some tone of yellow-orange or orange-yellow; tip of tail may be slightly lighter brown than the rest of the body; generally no pattern. Thank you very much Steven Reply from maybe 03/09/2000 06:22 AM: im not an expert but sounds like a coelecanth to me. Reply from Rainer 05/09/2000 12:19 PM: Certainly NOT a coelacanth. Reply from Gerald Jennings/Calypso 07/09/2000 12:13 PM: The difficulty is proportion. How high and wide in relation to length will give the missing clue.

We at Calypso will have a go from a scanned image -but we can certainly agree to no Coelacanth. Reply from Cecilia Morgan 17/09/2000 05:10 PM: I don't think that's a fish at all!

So if anyone can help my out with this that would be great. Reply from Thorke 10/09/2000 06:15 AM: Are you sure he didn't mean/say flatfish? These bony fish are divided into left and right "handed" (eyed) species (with some species containing some of both). The difference is which side the eyes migrate to, as the fish grows from larvae to adult. In the left-eyed flatfishes, the right eye moves to the left side of the head. If you lay the flatfish on the "blind" side (eyes up), and with the belly towards you, the head of the left-eyed/-handed flatfishes will face to the left. To the best of my knowledge this isn't the case with any of the skates and rays (which are hatched/born fully formed, and are lieing on their belly, not their side).

[355.] 13/09/2000 02:51 AM {Thread ID: 690} Petr Ráb   Tenth European Congress of Ichthyology – ECI X   Tenth European Congress of Ichthyology – ECI X Prague, September 3 - 7, 2001 “In the heart of Europe!" First Announcement and call for contributions. Invitation to ECI: On behalf of the Board of the European Ichthyological Society, we cordially invite you to attend the Tenth European Congress of Ichthyology to be held in 3-7 September 2001 in Prague, Czech Republic. Why Prague? Prague is centrally located in the middle of Europe, with convenient access for most participants. Participants will survive better and, we hope, cheaper here than in most large capitals, enjoying a flood of famous Czech beer. The ECI X in Prague also renew the original idea of alterning Congress sites between East and West as proposed in the early history of the European Cogresses of Ichthyology (Sarajevo in 1973, Paris in 1976, Warsaw in 1979, Hamburg in 1982, Stockoholm 1985, Budapest 1988, The Hague in 1991). In the days of the iron curtain - Congresses enabled mutual, but otherwise difficult contacts between many European ichthyologists, studying the same fauna, but unable to communicate freely. With the collapse of the iron curtain, East bloc economies faced new challenges making organisation of Congresses less feasible for some time. This is undoubtedly the main reason why the last two Congresses were held in the West (Oviedo in 1994, Trieste in 1997). It is a pleasure to come back to traditions in a way but in a Europe entirely different from that of 1973. There are no political barriers to meeting and Prague is no longer in the East. It is not in the West, nor in the South, nor in the North. The city is literally “In the heart of Europe". The Czech Republic is a rapidly transforming country, soon joining the European Union. A clear example of changing Europe. We deeply hope this will apply also for European ichthyology. Last but not least: Prague is one of those rare cities whose thousand-year history is preserved in its architecture. The city did not suffer any serious war damage for the last 500 years – a reason why it has been declared the World Heritage Site. Come and see! We look forward to greet you “In the heart of Europe!" Hosting institution: Institute of Animal Physiology and Genetics of the Academy of Sciences of the Czech Republic (CAS) Supporting institutions: Institute of Vertebrate Biology, CAS, Brno Moravian Museum, Brno National Museum, Prague Faculty of Natural Sciences, Charles University, Prague Czech Agricultural University, Prague University of South Bohemia, Èeské Budìjovice Programme: The European Congresses of Ichthyology are one of the world´s major international ichthyological meetings organised at three year intervals. The aim of ECI X is to provide a forum for exchange of scientific information which usually include history of ichthyology, anatomy and morphology, zoogeography, behaviour, physiology, ecology, taxonomy, cytogenetics, molecular genetics and ecology, molecular phylogeography, databases, as well as analytical contributions on evolution, biogeography, systematics and conservation of fishes. Applied topics (e.g. fisheries), unless they are strongly related to the above fields of ichthyology are not covered by European Congresses of Ichthyology Internationally renowned speakers will be invited to give key note reviews (45 minutes) for the main sessions. Other presentations will be given in multiple parallel sessions and oral contributions (15 + 5 minutes) are invited. Posters are invited from all participants. The prospective organizers of intra-ECI symposia and workshops should contact the convenor for any consultation, advice, help to make the proposed sessions successfull. Place of venue: All sessions will be held on the Campus of the Czech Agricultural University, Prague – Suchdol. The campus is located in a park area and is easily accessible by urban traffic (four bus stations from Metro station). Accommodation (preliminary information): Four 3 - 5 stars hotels located in near distance the Congress site will be available for participants of ECI X in adjacent parts of Prague – Dejvice which will be served by a shuttle bus. At the the Congress site, student dormitories will be available Official language: English. There will not be simultaneous translations. Publication of ECI X contributions: For those who wish to publish their contribution to ECI X, Folia Zoologica – an international journal of zoology, published by the Institute of Vertebrate Biology, CAS, (and indexed by most abstracting services) will publish a CEI X Supplement volume. All manuscripts will be peer-reviewed. More information about journal can be found at: http://www.kvetna.brno.cas.cz/pubser13_en.htm Congress tours: Several post-Congress tours will be proposed both touristic/social and specially designed for „fish heads“, including a sightseeing trip to the faunistically most diverse part of Czech Republic – the fluvial forest at the confluent of Dyje and Morava Rivers (Danube basin). Social programme: Prague and its vicinity offers numerous really interesting places to visit and enjoy. Historic medieval sites, Prague castle, a number of museums, theatres, historic nearby castles, pubs, coffee houses of well-known writers (Kafka), musicians (Smetana , Dvoøák), painters (Mucha), etc. to list only some of the numerous interesting sites waiting for your visit „In the heart of Europe!".

I am looking for information on the common blue ompok that is often found at pet stores. I am trying to find out about their color. Is it naturally blue and enhanced by food or someother non invasive method, or is it painted or injected. Please provide me with any information you can and also if you know how to maintain this color and if they are a very social fish and should be kept in multiples. I have not had any luck on the net finding this information. I will continue to check this site for any information you may have - andI thank you in advance for your help. Reply from Rainer 17/09/2000 10:44 PM: I don't know what species the blue ompok is. We have the name 'ompak' which refers to grunts, but these are not in the aquarium trade. Please try to provide the scientific name.

(They have all been reported from British waters recently with varying degrees of certainty) Sand tiger shark (Carcharius taurus) Hammerhead (Sphyrna zygaena) Couch's or Common Seabream (Pagrus pagrus) Pandora (Pagellus erythrinus) Saddled Seabream (Oblada melanurus) Bogue (Boops boops) White Seabream (Diplodus sargus) Mediterranean Horse Mackerel (Trachurus mediterraneus) Greater Amberjack (Seriola dumerili) Lesser Amberjack (S. fasciata) Guinea Amberjack (S. carpenteri) Almaco Jack (S. rivoliana) Dolphinfish or Dorado (Coryphaena hippurus) Many thanks, Doug Herdson Reply from Rainer 17/09/2000 10:26 PM: FishBase contains the established ranges for these species in three forms: free text, list of countries with indication of abundance, and latitudinal range. Most of the species you mention are tropical or subtropical and should not range to the UK. If you have specimens and thus can substantiate their occurrence in the UK you should consider publishing that, as it would indicated range extensions possibly as an effect of global warming.

Most books do not give a full account of the rarer or southern species. Fishbase gives a list by region but many of the socalled species are just synonyms of another species, not valid species. Can i get a list without synonyms? Reply from Nicolas Bailly 03/10/2000 07:10 PM: The FNAM covers the NORTH-EASTERN Atlantic, not the WESTERN Atlantic. For the North-western Atlantic, you have lists for Canada and USA, but I am not aware about a global list. As for the eastern part, a revised FNAM area check-list including Canarias Is. is to be published soon in a book and on the web as a result of an European Community research program (European Register of Marine Species). As soon as the list is updated, I will publish here the URL (the current list is out-dated). For the south-eastern part, you can look at the CLOFETA, Check-List Of the Fishes of the Eastern Tropical Atlantic, Quero et al. (eds), 1990, Unesco, SEI, JNICT, 3 vols., 1492 p. Then in the Smith Sea Fishes for further south-east part. CLOFETA is a check-list like CLOFNAM, ie only with synonymies and references to some key-facts (not the key-facts themselves), and not an ichthyofauna like FNAM. For further information, please contact me directly at bailly@mnhn.fr N. Bailly Reply from Thorke 04/10/2000 06:21 AM: Oooops, a classic example of the need to think before you write (east/west, whats the difference?), I hope Rainer will delete my erroneous entry (and this one). But FNAM is a good book nonetheless, I am looking forward to the new edition! Reply from Thorke 30/09/2000 03:17 PM: A good start is "Fishes of the North-eastern Atlantic and the Mediterranean" ("FNAM") by Whitehead, Bauchot, Hureau, Nielsen & Tortonese (eds.), UNESCO 1984. Very good for the area mentioned in the titel, but does not cover the area from the Canary Islands and southward.

What are the methodologies used in if I choose to use this in my thesis? (I'm specially interested in the length-weight relationships) Are their references in which I could use in my study? Reply from Rainer 08/10/2000 10:33 PM: Length is easier measured than weight, but weight is often needed for management models. Standard weight is a new technique that lets one assess the condition of the fish. Diet information is needed for ecosystem models. Growth information is needed for fisheries management models. Reply from Upali Amarasinghe 20/10/2000 08:48 AM: The other advantage in measuring length is that length in a particular age class of fish is normally distributed. As length and weight have two different dimensions (length is linear whereas weight is three-dimensional which is related to volume), weight is not normally distributed. As such length data can be readily used in parametric statistical analyses.

It was approximately 3 feet long and about a foot in diameter and had a fin that rose about 7 or 8 inches from the surface. The strange aspect about the fish was that it used this fin as a means of propulsion. From a vertical postion it would sweep the fin backwards to give it forward thrust (which placed the fin totally under the water,) then lift the fin out of the water and start the movement again. The fin appeared to have a serrated trailing edge. It was not at all scared of my presence nor did it appear to come up for air. It swam just under the water's surface. Any clue on what I saw??

It was photographed near the Caymans but nothing is known of it. It is not Torpedo nobiliana because that occurrs farther north and is dark in color. I saw on fishbase a Torpedo andersoni but it is only found on Florida straights. Is there another species of Torpedo ray in the W. Atlantic? Reply from Rainer 25/10/2000 02:06 AM: In Search FishBase, 'Information by Country/Island', select the Jamaica and click on the 'Marine' radio button to obtain a list of 507 species we have so far assigned to those islands, including two electric rays of the genus Narcine. For Cayman Islands we had no good checklist so far, thus only 250 species are assigned to it, and no rays.

Are there any aquarists or tetra-specialist out there that can help me? The fish were caught in Rio Cuieras near Manaus, both in open water, and in shallow pools adjacent to the river proper.

[412.] 16/11/2000 09:07 AM {Thread ID: 810} ray   West-->East Atlantic   I've noticed that there are alot of West Atlantic fishes that have ranges that extend to the Eastern Atlantic. Why, then, are there so few Eastern Atlantic fishes that extend into the West Atlantic. There is an equatorial current heading west, there are islands to jump to, and Brazil is close to westernmost Africa. It seems to make sense that there would be a migration of eastern atlantic fishes to the brazil at least. There is a similar environment on both sides in the equatorial region. Could there be species but we haven't discovered them yet? Is Brazil well studied? How is it easier for the West Atlantic species to cross over to Africa and not vice versa? Reply from JER 02/12/2000 01:14 AM: I have little knowledge of the eastern Atlantic fish fauna, so I do not have much to offer. I was not aware that there are any significant number of western Atlantic fishes that have crossed over to eastern Atlantic. The span of open ocean is broad enough to preclude the transport in ocean currents of fish larvae of most species of shore fishes. When a species is on both sides of the Atlantic, how do you decide with confidence which side is the place of origin? Consider the jewfish (E. itajara). Now it seems to be an American species because it is much more widely distributed there (and into the E Pacific), as well as being named from Brazil. But it is possible that it originated in West Africa. Based on having a broad distribution in the eastern Atlantic, Epinephelus marginatus would seem to be an eastern Atlantic fish as it is known in the western Atlantic only from Brazil.

If you do not have this book, it is available from Jerry Allen (his e-mail address is: tropical_reef@bigpond.com) I have to agree with the person who wrote you that Carcharhinus longimanus and Isurus oxyrinchus are oceanic species and hence probably not in Thai waters, if the writer is correct that there is no deep water that can be considered as Thai.

Reply from Daniel Pauly 12/01/2001 03:04 PM: There is a huge literature on ITQs, and whether they are 'good' or not depends on the structure of the fisheries (industrial or artisanal), and on local perceptions of the legitimacy of privatizing what is, after all, a public good. ITQs are no panacea, and while useful to address the issue of overcapacity within firms, they do not provide a solution to issues such as high-grading of catches, and discarding of by-catch, and other ecosystem impacts of fishing, A comprehensive discussion of ITQs may be found in the report devoted to this topic by the US National Research Council, an arm of the U.S. Academy of Science (see their web page to download a free copy).

[433.] 11/01/2001 01:10 PM {Thread ID: 853} cindy kolar   thermal categorization   Hi again! How are fishes categorized into polar, temperate, subtropical, or tropical? Is it based only on latitudes inhabited, or is it on broad envirnomental tolerances? If on broad temperature tolerances, how is subtropical defined? Reply from Rainer 12/01/2001 12:52 AM: It is based on the overlap of latitudinal range of a species with a map indicating the respective zones. Deep-sea fishes are marked as such and excluded. Species that range from temperate to tropical are included in the subtropical category. Let us know if you disagree with some of our assignments, so we can have a second look.

I'm working on a script which refers to the number of fish on earth, particularly as compared to the relative number of humans. Trouble is, at the moment, I'm still searching for the appropriate figure. The usual suspects (Encarta; Essentials of Oceanography; The Oceans: A Book of Questions and Answers; Life on Earth, etc) turned up figures for the estimated numbers of species, but none for total population. If YOU know, do tell. Please cite appropriate reference in your response, if possible. Thanks in advance for your help, Louise Reply from Rainer 17/01/2001 04:03 AM: I don't think that such an estimate exists, as stock assessment is done for only a few hundred of the 25,000 recent species. If I had to do it I would start from primary production in the oceans, estimate the share that fishes typically have of the resulting secondary biomass, and use the typical size (weight) distribution of fishes to turn that into numbers. To give an example for the Peruvian anchoveta (Engraulis ringens): catch in 1971 was 13,059,900 metric tonnes (FAO); average weight is 10 g; that yields 1,305,990,000,000 individuals caught; about the same number should have survived in the sea. I have no clue how to go about freshwater fishes.

In parole povere, le informazioni sono sempre benvenuti, perche il meglio e' il nemico del buono. Habbiamo comunque un principio indispensabile per mantenere trasparente la fonte delle informazioni e salvaguardare l'integrita' della base: ci si mette solo materiale pubblicato in modo da poter indicare una fonte (chiaramente grazie a questa organizzazione dei dati molti errori sono stati identificati, altrimenti difficili da scoprire in pubblicazioni convenzionali, tabelle sequenziali etc.). Ora, le pubblicazioni possono essere di diversi tipi, non solo articoli nelle reviste di massima scienza o libri di questo genere. Stiamo discutendo come poter meglio accommodare contributi di esperti pratici come lei che ci vengono qualche volta offerto - il protocollo Fishwatcher ed altri routines gia disponibili sono un tentativo nostro, forse da perfezionare, di incentivare la communicazione di osservazioni sul terreno di una ampiezza che non puo essere mai garantita dalle truppe ridotte degli ricercatori. Quindi pensiamo che ci sia ampia possibilita' di collaborazione e complementarita'. In sintesi, siamo molto aperti alla collaborazioni ed al ascolto di proposte (in piu' si a piu' idee).

A message I received from a member of the public (I am a fish collection manager with a museum in the States). We all had a good laugh. Anyone have any ideas?? Herewith follows the message. ------------------------------------ I am trying to identify a fish that attacked my girlfriend, i have compiled a partial description of it, and the location of the incident, and if you can shed any light on it, id be much appreiative. The incident occured at Fort Walton, Dresdin. in the later half of 1998, after a hurricane had been through. The beaches were strewn with seaweed, kelp? and sea snails/slugs. My girlfriend went for a swim, but was covered in these fish which bit her. She hurried out of the water and into a shower, and the fish died. The fish are described as: about half an inch long, clearish/translucent, wish very prominent teeth- i think like a pirhanna not sure, but possibly. It appears they hunt in schools. Each fish had to be removed once they died in the shower, because they were still biting her. Shortly afterwards she developed an itchyness and severe rash - which we are contemplating being related. It is my theory that these fish being colourless were probably from deep waters and got stirred to the surface by the hurricane. I havent been able to track down a fish that matches the description, not reports of similar incidents - though there was one page talking about a fish biting incident, but the link had since gone dead. Any light you can shed or help you can give on the matter is greatly appreciated. --------------------------------------- Hhhmmmmmmmmm!!!!!!!

[469.] 07/03/2001 01:00 AM {Thread ID: 923} Grouper   Impact of Barrier Net Trap   Dear All, I would like to know the opinions of this forum concerning the use of Barrier net for catching wild post larvaes (Pl's)of fish. In South East Asia, the trade of live fish (for aquaria and human consumption) is a very big business. Many people use poisons (cyanide) and bombs to catch fish alive. At the present time, the reef is extremely damaged in many area. The population of grouper (such as Cromileptes altivelis) and Napoleon (Ceilinus undulatus) is drastically decreasing. The fishermen use to catch groupers when they rally for breeding! Furthermore, napoleons are caught when they are still small (around 800 gr.) and they don't have the time to multiply. It seems also that the customers start to realise that these fish contain traces of poison!!!! Th situation is so bad that people who are involved in this business are now asking to find other solutions and would like to rear these fishes. The cost of construction of hatcheries is quite onerous and is not conceivable for them. Thus, by using barrier net it will be feasible to catch wild Pl's and to grow these fish in tanks or in cages. This method could enable local fishermen to grow their crop rather than to risk their live (diving) and to destroy thier own environment. What will be the impacts of this method on the ecosystem? Do you think this method is feasible and could be a good alternative system? I hope my english to be enough clear. I am looking forward to read your reactions conncerning this subject. Cheers, Chromileptes Reply from test 04/04/2001 10:05 PM: test Reply from Rainer 07/03/2001 03:01 AM: The method of choice to catch larvae just prior to settlement would be light traps, not barrier nets. Light traps can be built from cheap material and are successfully used in the Great Barrier Reef and also in the Caribbean. Reply from Chromileptes 07/03/2001 04:58 AM: Thank you for responding to my message Rainer. It is true that I have omit to mention light traps. Light traps are very cheap but are not widely use (for my knowledge) in S.E. Asia. These two methods should have the same impact on the ecosystem. What are the impacts on the ecosystem? Regards, Chromileptes Reply from Rainer 09/03/2001 04:24 AM: Light traps have no known environmental impact and very high survival rates of post larvae, so I think they are the method of choice. As mortality at and after settling is extremely high, I don't think the larvae captured by light traps play any role. I am not sure how survuval rates etc. and environmental impact are with barrier nets. I suggest you study the respective literature on light traps. Doherty, Munro, and Bell, for example, have published on the subject. Reply from eli 13/03/2001 06:24 PM: test

[474.] 11/03/2001 08:38 AM {Thread ID: 935} chinook1   Pacific Northwest fisheries   I am involved in salmon conservation out here on the west coast in Oregon. After browsing this forum I have come to the conclusion that it is full of very knowledgable individuals. My question is this, does anyone know where I could find information on the ability or inability of hatchery raised adult salmon and steelhead to spawn naturally and successfully in Northeaastern US streams, or western streams for that matter? The recent debate suggests that the single most important factor limiting wild stocks in the west from a comeback is the presence of hatchery fish which are unable to successfully reproduce, supposedly. The argument goes that these hatchery fish attempt to spawn with wild fish, but when breeding is unsuccessful the population is extremely impeded. I am looking for infoirmation that would support this argument. Any help is gratly appriciated.

[476.] 11/03/2001 01:49 PM {Thread ID: 937} Mike   Piranhas in the former Soviet Union???   I was watching some quiz show on TV the other day, and the contestants were to say if a given statement was true or false. One was that there are piranhas in the (I think) Caucasus region in the former Soviet Union, and the guy said "No" (cause that makes sense to me as well). But to my (and the guy's) surprise, they said it's TRUE, that there ARE piranhas there! That sounds like a joke to me but that's what they said! Can anyone here confirm that it's really true, and if so, where do they come from? How can a South American species live there? I still won't believe it until someone can confirm this. Reply from Rainer 12/03/2001 12:22 AM: Piranhas are often released when they get too big and boring for home aquariums. If they are put in, e.g., a lake warmed by cooling water outflow, they will survive until the factory has a longer breakdown. In warm countries, however, these releases by aquarists are a major threat to native species (such as in Hawaii).

[478.] 12/03/2001 09:27 PM {Thread ID: 941} CHRIS   ID for strange pacific north west fish   Hi guys/gals, Was night diving near Vancouver, BC Canada yesterday and came across a very strange eel/snake like fish. It was free-swimming about 5 feet below surface in about 20 feet of water but close to some large rock pilings. The fish was 2 to 3 feet long and very skinny - very much like a compressed garden snake in both shape and movement with a dorsal fin running the length of the fish - was balck with while/dull grey stripes (horizontal)in colour. The strangest thing about it was it's thin elongated mouth (3 to 4 cm long) where the upper lip/jaw curved gently upwards while the lower jaw curled gently downwards. Haven't been able to figure out what this fish was but we got a very good look at it for several minutes - probably because of our bright lights. Any help with this ID or where I might look for further info much appreciated.Thanks in advance. chris Reply from Thorke 13/03/2001 06:39 AM: How about a snipe eel?

Reply from corey 26/03/2001 08:20 PM: merlucious has 2 dorsal fins, and 1 anal fin, whereas the true cods will have 3 dorsal fins, and 2 anal fins. merlucious usually refers to the family of hakes whereas the gadidae are the true cods ( not the false cods ie lingcod or rock cod - these are the hexangrammidae and the scorpaeniformes. Hakes have frontal bones of the head seperate and the ribs are attached to the anterior vertebrae whereas the cod frontal bones are joined and the ribs begin at the fifth or sixth vertebrae.

So it seems that the biting behaviour of "your" Balistapus undulatus is a common occurrence, perhaps related to their territoriality(?)

I can find 2 filefish species (Aluterus scriptus & Cantherhines dumerili) and 8 triggerfish species (Balistes polylepis, Canthidermis maculatus, Melichthys niger, Melichthys vidua, Pseudobalistes naufragium, Sufflamen verres, Xanthichthys lineopunctatus & Xanthichthys mento).
