| Abstract |
The stomach contents of 308 adult amberjack, Seriola dumerili (Osteichthyes, Cararrgidae) were analysed to investigate the food and feeding habits of this species. Fish occurred in 79.7% of non-empty stomachs, accounting for 79.5% of prey in number and 71.0% in weight; cephalopods occurred in 26.8% of non-empty stomachs, accounting for 20.5% of preys in number and 29.0% in weight. The prey items occurring most frequently were Boops boops, Loligo spp., Sardinella aurita, Sardina pilchardus and Sepia officinalis. Pelagic preys occurred overall less frequently and in lesser amounts than demersal ones; moreover males fed much more intensely on demersal preys than females. The amberjack is an essentially piscivorous predator. Though commonly considered a "pelagic" species, it does not seem dependent on pelagic food sources in the central Mediterranean, at least during the spawning season. |
