Lipid profiles of Threadfin bream (<i style="">Nemipterus japonicus</i>) organs

Abstract

Present study of the lipid content in different organs of marine fish Threadfin bream (<i style="">Nemipterus japonicus</i>) indicates that a major amount of lipids are accumulated in liver (6.22%) when compared with remaining organs like muscle (2.7%) and skin (1.0%). Cholesterol studies reveal that muscle (36.2%) is having more quantities than liver (32.4%) and skin (24%). Fatty acid composition reveals that the lipids of each organ of threadfin bream are enriched in the unsaturated fatty acids and all the organs were found to be rich in linoleic (C_{18: 2}), oleic (C _18:1) and palmitic (C_{16: 0}). The present study further elucidates that a considerable amount of two physiologically important n-3 PUFAs, i.e. EPA and DHA were found more in skin (1.6% and 0.5%) and liver (1.6% and 0.6%) than in muscle (1.4% and 0.4%).
