| Remarques | Occur inshore (Ref. 75154). There is little information on the life cycle movements of threadfin salmon. Tagging programs (Ref. 28741) have shown that adult blue threadfin move long distances along the coastline for at least 150 km. Blue salmon form large schools in feeding and spawning habitats in coastal shallows (Williams 1997). 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). |
