Abstract
Atomic absorption spectrophotometery showed significant levels of contamination by Cd, Hg, Cu, Mn, Zn, Pb, Cr and Sn in fish habitats. Fatty acids from meat were detected by gas chromatography. C12:0, C20:0, C16:1(n-7), C16:1(n-9), C18:1(n-9), C20:1(n-9), C18:2(n-6), C18:4(n-3), C22:4(n-6), C20:5(n-3) and C22:4(n-6) fatty acids were found missing in fish obtained from area of higher pollution when compared to farmed fish.C16:1(n-7), C20:1(n-9), C20:2(n-6), C22:4(n-6) and C22:5(n-3) were found missing in the fish collected upstream to the areas of high intensity pollution. Loss of these important fatty acids indicates the sensitivity of the fish even in response to the lower intensity of pollution. Farmed fish showed optimal concentration of each fatty acid. Significant differences (p<0.05) were observed in fatty acid profiles of different species when each was compared in relation to their own habitats. Habitat of even lower intensity pollution confiscates fatty acids of omega series and lower down the

In comparison with terrestrial animal meat, Bottom feeder Cirrhinus mrigala (Indian major fish lipids are beneficial to human health by reducing carps) collected from highly polluted areas, less polluted areas and farmed fish were analyzed for the estimation of fatty acids profile
The data shown for individual fatty acid of total lipids are limited to, fish flesh of two category habitats
