Biology
Adults are generally found offshore, usually near surface, in schools (Ref. 2850). Juveniles associate with drifting seaweed (Ref. 12114, 12115). Feed on small crustaceans, and eggs and larvae of fishes. May glide above the surface of the water when moving away from predators. Prey of Thunnus alalunga and other scombrids (Ref. 9339). Oviparous, with larvae neustonic (Ref. 36573). Eggs are attached to one another and to floating objects via filaments on the shell surface (Ref. 36573). Utilized dried or salted, canned and frozen; also used for fishmeal and pet food; can be pan-fried and broiled (Ref. 9988).
