ABSTRACT
The aim of this study was to evaluate the performances and the flesh quality of Pagellus bogaraveo fed with diets containing rice protein concentrate [RPC, 70% crude protein (CP) and 10% ether extract]. Three isoproteic and isoenergetic (CP 47%, 22 MJ/kg DM) diets were formulated with an increasing level of RPC 0%, 20% and 35%. The fish (mean weight 75 g) from the Messina Straits were randomly distributed in 12 tanks (3 diets x 4 replications, 10 fish/tank). The daily ratio (1.5% of the fish biomass) was updated every 15 days. Biomass gain showed an opposite trend to the RPC diet inclusion. No differences appeared in the somatic indexes. Differences appeared between fatty acid profiles of the dorsal muscle. Fatty acid of series n-6 increased and fatty acid of series n-3 decreased in fillets of fish fed with increasing levels of RPC. The inclusion of RPC in the diets, as a partial replacement of fish meal (20%), is possible without affecting the growth performance and fillet quality.
