Adults inhabit continental shelf and slope waters (Ref. 6390). Reported from depths between 22 m (Ref. 58489) and 400m (Ref. 30458). They are schooling species, usually aggregating close to the sea bed (Ref. 26498) although there is some evidence that they move into the middle water column at night (Ref. 30459). Juveniles recorded offshore to a depth of 100 m and sometimes entering estuaries, often in association with jellyfish (Ref. 9563) and schooling close to the surface. Feed mainly on salps but also takes euphausiids, krill, crabs and small squid (Ref. 9072). Marketed fresh and frozen; eaten steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988).
Determinate annual fecundity. Females spawn three batches of eggs in a season (Ref. 86821).
