LIPID FATTY ACIDS, GROWTH AND COMPOSITIONAL CHARACTERISTICS OF FARMED COD ( GADUS MORHUA )
ABSTRACT. The effect of a formulated diet rich in lipids on the compositional characteristics and quality of cod ( Gadus morhua ) was investigated. Changes in the proximate composition of fillets and liver tissues of cod ( Gadus morhua ), fed intensively over a 20‐weekk period, was monitored. The co...

| Summary: | ABSTRACT. The effect of a formulated diet rich in lipids on the compositional characteristics and quality of cod ( Gadus morhua ) was investigated. Changes in the proximate composition of fillets and liver tissues of cod ( Gadus morhua ), fed intensively over a 20‐weekk period, was monitored. The content of lipids in the fillets increased from 0.74 to 0.94% and corresponding values for liver were 58.90 and 75.92%, respectively. Over the same period, the hepatosomatic index of fish increased from 4.41 to 12.70%, reflecting the accumulation of lipids in the liver of farmed cod. The content of omega‐3 polyunsaturated fatty acids (PUFA) in the muscle tissues changed from 52.13 to 55.82%. Corresponding change in the liver was from 17.94 to 26.12%. The major increase in the omega‐3 PUFA was due to an increase in the content of docosahexaenoic acid. |
