Abstract

The muscle lipid, fatty acids and total cholesterol profiles of the spiny cheek grouper, Epinephelus diacanthus, collected from south-west (Arabian Sea) and south-east coasts (Bay of Bengal) of India were evaluated over four years (2008-2011) with regard to three seasons (pre-monsoon, monsoon and post-monsoon). Fatty acids were correlated with chlorophyll-a concentration and sea surface temperature. Lipid content, total polyunsaturated, eicosapentaenoic and docosahexaenoic fatty acids of the samples from the south-west coast showed positive correlation with chlorophyll-a concentration during the monsoon (r(2) = 0.93, 0.97, 0.97 and 0.99, respectively). Higher hypocholesterolaemic/hypercholesterolaemic ratio (>1.0) and low atherogenic (<1.2), thrombogenicity (<= 0.6) indices make the groupers collected from the coast of the Arabian Sea a valued candidate species for human nutrition. High levels of n-3 fatty acids (>19% during post-monsoon), important in the human diet for their platelet anti-aggregating and blood pressure-reducing properties, for groupers collected from the south-west coast, with higher n-3/n-6 fatty acid ratio (>5.1) proved this species from the coast of the Arabian Sea to be a desirable item in the human diet.
