Abstract: The effect of dietary inclusion of two type of crab meal on growth, feed utilization and skin coloration performance was investigated in a growth trial with red porgy (Pagrus pagrus) of 233g initial body weight, during 6 month feeding period. High quality fish meal and fish oil diet was used as a control (Diet C). Protein of fish meal in the control was replaced by increasing dietary levels of protein derived from a river crab meal (Procamburus clarkii) (CR) and a marine crab meal (Chaceon affinis) (CM) at 10% and 20% each of them. Regarding growth results, fish fed the CM20 diet showed the highest values in absolute final weight and percent of the initial weight. For animals fed the crab meal based diets, the colour result was better than that of fish fed the control one, showing skin redness similar to that of the wild specimens. For both ingredients, increasing dietary inclusions were accompanied for an increment of the colour saturation, being in this case the obtained value for the CR meal higher than those for the CM meal. Present results indicate that crab meals used in this study are suitable as partial replacers for fish meal in diets for the red porgy.
