Abstract: The inclusion of two different crab meals in diets on fillet quality parameters was investigated in a six month growth trial with red porgy (Pagus pagrus). A high quality fish meal and fish oil diet was used as a control (Diet C). Fish meal protein in the control diet was replaced by increasing levels of protein from a river crab meal (Procamburus clarkii) (CR) and a marine crab meal (Chaceon affinis) (CM) at 10% and 20% each of them. The inclusion of both crab meals in diets, either at 10% and 20% substitution levels, did not affect the texture quality parameters of flesh except for the adhesiveness, where animal fed on CR20 showed the smallest value respect to those fed the Diet C. Compared to the control fish, a reduction of the fillet lipid oxidation indicated by the Tbars index was observed for fish fed both crab meal based diets, at the higher inclusion level (20%). Increasing dietary levels of the marine crab meal showed an increment of the monoenoicos, n-9 and oleic fatty acid content in the fillets. Results indicate that both crab meals used in present study are suitable as alternative ingredients for red porgy diets in terms of fish flesh quality.
