Fatty acid metabolism in the freshwater shrimp, Macrobrachium rosenbergii

Typescript (photocopy).Freshwater shrimp, Macrobrachium rosenbergii, were fed experimental diets containing no fat, purified fatty acids (linoleate, linolenate, palmitate) and lipids of plant and animal origin. Gas chromatographic analysis of lipid extracts from the hepatopancreas, cephalothorax and abdominal tissues of animals treated for 35, 65 and 100 days revealed 23 identifiable fatty acids. Major components of the fatty acid profile were 14:0, 16:0, 18:0, 16:1n-7, 18:1n-9, 16:2n-4, 18:2n-6, 18:3n-3, 20:4n-6, 20:5n-3 and 22:6n-3. Minor components (those with individual concentrations
