Fatty Acid Composition of Channel Catfish (Ictalurus punctatus) Fed Diets Containing Dried Waste Eggs

Fingerling and adult channel catfish (Ictalurus punctatus) were fed diets containing 14.25% and 28.5% spray-dried waste egg product for three and four months, respectively. The fatty acid profiles of the fish reflected those of their respective diets. Catfish fed egg diets had significantly lower (p < 0.05) levels of long-chain polyunsaturated fatty acids and significantly higher amounts of medium-chain polyunsaturated fatty acids than fish fed the control diet. Incorporation of eggs into the fish diets had no detrimental effect on fish growth or product quality.
