Colour of upper sides of head and trunk with slight darkish silver tinge, becoming lighter in lower sides; anterior margins of first and second dorsal fins blackish, remaining parts translucent and slightly blackish, respectively; pectoral fin membranes vivid yellow in life, except in large specimens > ca 35 cm SL which is dusky yellow; pectoral filaments white; anterior margin of pelvic fin yellow and other parts white; base of caudal fin yellowish, other parts blackish (Ref. 41639, 57343).
Body shape (shape guide): elongated; Cross section: compressed.

Biología     Glosario (por ej. epibenthic)

Adults occur mainly over shallow muddy bottoms in coastal waters. Also enter rivers (Ref. 3479, 6390, 11230). Juveniles found in estuaries. During winter, adults ascend the rivers. They usually form loose schools, although larger fish are more often observed in pairs or singly (Ref. 6390). Feed on prawns and fish (largely members of Mugilidae, Engraulidae, and Sciaenidae) with occasional polychaetes. Frequency of crustaceans to fish in the diet varies seasonally. Larvae (7-30 mm TL) feed mainly on copepods and mysids but also take shrimps and prawn larvae (Ref. 57343). Juveniles (31-60 TL) feed on prawns shrimps and mysids (Ref. 57343). Protandrous hermaphrodites. Marketed fresh, frozen, and dried or salted.

Ciclo vital y comportamiento de apareamiento Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

In Australia, fish are males at 24-47 cm FL, hermaphrodites at 25-46 cm FL and females at 28-72 cm FL. On the northeast Queensland coast, most blue threadfin are females by 45-50 cm FL. Hermaphroditic blue threadfin develop fom 1-2-year-old fish, and females first appear as 2-3-year-old individuals (Ref. 28736). Male fish probably commence sex reversal immediately after spawning (ie about April-May) and this condition may persist until after the next spawning period (Ref. 28736). The progression from hermaphrodites to females is complete by the following season. There is little information on the larvae, although nursery areas are known to be lower estuaries, tidal swamps and lagoons, and shallows along the foreshores (Williams 1997).
