Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Found in neritic waters close inshore (Ref. 13628). This schooling species is an opportunistic predator which feeds on virtually everything within its range, i.e. crustaceans, fishes (mainly clupeoid), squids, heteropods and tunicates. Eggs and larvae are pelagic (Ref. 6769). Specialized traps (madragues) are used in Tunisia and Morocco. Diving bird flocks may indicate large schools (Ref. 9710). Utilized fresh, dried-salted, smoked, canned and frozen (Ref. 9987). A popular game fish (Ref. 9710).
