Family:  Chanidae (Milkfish)
Max. size:  180 cm SL (male/unsexed); 124 cm SL (female); max.weight: 14 kg; max. reported age: 15 years
Environment:  benthopelagic; depth range 1 - 30 m, amphidromous
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.
Diagnosis:  Dorsal spines (total): 2-2; Dorsal soft rays (total): 13-17; Anal spines: 2-2; Anal soft rays: 8-10; Vertebrae: 46-46. This species is characterized by the following: body elongate and somewhat compressed; mouth small and toothless; single dorsal about mid-level of the body; pectoral fins falcate; caudal fin large and deeply forked; no scutes on belly; branchiostegal rays 4. Colour of the body olive green dorsally; flanks silvery; unpaired fins with dark margins (Ref. 49, 117228).
Biology:  Adults are found in offshore marine waters and shallow coastal embayments, but also frequently enter estuaries and occasionally penetrate freshwater streams (Ref. 44894, 52331). They 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. Mature adults 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 or frozen. Brood stocks can be raised and spawned in captivity to produce larvae in the hatchery (Ref. 12868). This species can thrive and grow in water as hot as 32° C (Ref. 9987).
