A schooling species (Ref. 9563). Reported from between depths of 86 m (Ref. 58489) and 500 m (Ref. 5325). Juveniles occur near the surface, often with schools of clupeids while adults are found near the bottom in deeper water (Ref. 3394). Adults feed mainly on larger zooplankton (Ref. 3394). An excellent food fish; marketed fresh or frozen (Ref. 3394).
Asynchronous batch spawner with indeterminate fecundity (Ref. 115109). Spawns once every 3-5 days (Ref. 115109).
