Fatty Acids Composition of Someselected Indian Fishes

Abstract

A comparative study on the fatty acids content of four Indian fishescatla (Catlacatla), rohu (Labeorohita), magur (Clariusbatrachus) and pangas (Pangasianodonhypophthalmus) were carried out in the present study. The proximate analysis revealed that the protein content of catla, rohu, magur and pangaswas 10.11%, 9.53%, 14.87% and 13.6%(% of wet weight), respectively. The total lipid content was generally high, ranging from 1.2 % to 7.9 % and crude ash ranged from 1.25% to 2.7%. Saturated fatty acids (SFA) were most abundant in catla(60.92%) while in rohu(52.28%),pangas (47.15%) and magur (39.85%) respectively. Magurwas rich in polyunsaturated fatty acids (PUFA)(25.56%) than pangas (23.37%), rohu (15.84%) and catla (12.5%). The omega 3 and 6 ratio ( 3/ 6) was ranging from 0.706 to 6.544 and catlashowed the highest ratio.The most abundant fatty acid in all fishes was C16:0, ranging from 32.2% to 38.23%. The other major fatty acids detected were C18:0, C18:1 and C18:3. This result clearly shows that the importance of fish nutrition in the human diet for combating the diseases like heart problems, cholesterol and many nervous related problems.
