Scientific Name
Arripis trutta

Common Name
Australian salmon

Biology
Inhabit continental shelf waters including estuaries, bays and inlets (Ref. 6390). Found between depths of 30 m (Ref. 33616) and 39 m (Ref. 58489). They enter rivers (Ref. 9002). Juveniles form school in shallow coastal bays and estuaries; adults move in large schools along shores (Ref. 9002), and can move over reefs in depths just sufficient to cover their bodies (Ref. 6390). They form large surface aggregations in deep water (Ref. 6390). Feed mainly on fishes but also on pelagic crustaceans, especially krill (Nyctiphanes australis). Take also food from the seabed. Fish smaller than 10 cm feed predominantly on copepods (Ref. 9072). Utilized fresh, canned and frozen; can be steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988).
