Ecology Summary - Euthynnus alletteratus

Langue:

Réf. Princ.	Collette, B.B. and C.E. Nauen, 1983
Remarques	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. School by size together with other scombrids but have a tendency to scatter during certain periods of the year. Varied diet and target in all prey although with a certain preference for pelagic species (Ref. 28173).
