Abstract
The composition of body and visceral fats from rohu (Labeo rohita) and nain (Cirrhina mrigala) were studied. Preliminary separations of the fatty acids into groups differing in unsaturation were carried out using the Li and Pb salts in acetone and ethanol, respectively. Their compositions were studied by the ester-fractionation procedure. The fishes rohu and nain belong to different genera, and significant differences were found in the proportions and degree of unsaturation of their C16, C18, C20 and C22 groups of unsaturated acids, and also in the amounts of total saturated acids and of stearic acid. The high saturated acid content of the fats is remarkable, especially in fats from rohu. The increase in the percentage of stearic acid seems to have been at the cost of unsaturated C18 acids, and thus may indicate bio-hydrogenation. The fat content of the viscera of these fish is about 45%.
