Abstract
Preliminary data on the diet and trophic competition between Scyliorhinus canicula and Raja clavata, caught in the seas surrounding Sardinia (central-western Mediterranean),during trawl surveys carried out from 2005 to 2008 are given. The low values of Levin and Shannon-Weaver indexes showed that these two species are specialized predators. The ontogenetic analysis of the diet showed different predatory patterns.Items in DSpace are protected by copyright, with all rights reserved, unless otherwise indicated.
