Summary for Chanos chanos Larvae
Milkfish

Chanos  chanos  (Forsskål, 1775)
Family:	Chanidae (Milkfish)
Order:	Gonorynchiformes
Class:	Actinopterygii (ray-finned fishes)
English name:	Milkfish
Distribution:	Indo-Pacific: along continental shelves and around islands, where temperatures are greater than 20°C. Red Sea and South Africa to Hawaii and the Marquesas, north to Japan, south to Victoria, Australia. Eastern Pacific: San Pedro, California to the Galapagos.
Adult biology:	Found in offshore marine waters and shallow coastal embayments, but also frequently enter estuaries and occasionally penetrate freshwater streams (Ref. 44894). A marine species which enters estuaries and rivers (Ref. 52331). Adults occur in small to large schools near the coasts or around islands where reefs are well developed. Eggs and larvae are pelagic up to 2-3 weeks. Older larvae migrate onshore and settle in coastal wetlands (mangroves, estuaries) during the juvenile stage, or occasionally enter freshwater lakes. Juveniles and sub-adults return to sea where they mature sexually. Spawn only in fully saline water. Larvae eat zooplankton; juveniles and adults eat cyanobacteria, soft algae, small benthic invertebrates, and even pelagic fish eggs and larvae. Larvae are collected from rivers and are grown in culture ponds into juveniles, which are marketed fresh, smoked, canned and frozen. Brood stocks can be raised and spawned in captivity to produce larvae in the hatchery (Ref. 12868). Can thrive and grow in water as hot as 32° C (Ref. 9987).
Diagnosis:	Yolk is completely absorbed on the 3rd day. Eyes well pigmented. Functional mouth with an opening present. At flexion, body becomes transparent and stomach contents visible. Larvae (and adults) lack teeth. Pigmentation: Pigments scattered over the upper half of the body and on peritoneal wall. Mediolateral pigment on the caudal region proceeding anteriorly. Pigmentation on head region increases. Sequence of fin development: pectoral, caudal, dorsal and anal, pelvic. See also LARVAE table.
Climate Zone:	tropical; 15 - 43°C; 46°N - 52°S
