Preliminary data on the feeding ecology of some selachians from the north-eastern Aegean Sea

Abstract

    The diets and comparative feeding ecologies of some selachians caught along the Turkish coast of northern Aegean Sea were determined for the first time. The diet of Scyliorhinus canicula was composed of teleosteans, crustaceans, cephalopods and polychaetes. Raja clavata fed primarily on crustaceans, with the main prey items being Parapenaeus longirostris, Liocarcinus spp., Goneplax rhomboides, Xantho spp. and Munida spp. Teleosts and cephalopods were also consumed by the thornback ray.
