ABSTRACT

A 12-week feeding trial was conducted to determine the effects of a commercial and a crab meal-supplemented diet on sensory properties of southern flounder ( Paralichthys lethostigma). Proximate analysis, color, fatty acid composition, texture and sensory analyses were performed on the fillets. A significant difference in flavor was found between fillets fed on a commercial or a crab-meal supplemented diet. No significant difference was found between the fish fillets when comparing fat, protein, fiber content and texture. However, fatty acid composition and color were significantly affected by dietary treatment. The data suggest that crab-meal supplemented finishing diets could be utilized to enhance final product quality.
