Biochemical composition of five marine fish; grey bamboo shark, yellow margin trigger fish, paleedged stingray, laced moray and Japanese leatherjacket fish from the Gulf of Mannar, India were evaluated. Moisture, protein, lipid and ash content for the samples ranged between 75.07-76.74, 17.99-20.97, 1-3.5 and 1.46-1.93% respectively. Profiles of heavy metal, fatty acid and amino acid data were also collected. The predominant fatty acids recorded in all five species were docosahexaenoic acid (DHA), arachidonic acid (AA) and palmitic acid. All five species contain high content of different essential and non-essential amino acids namely glutamic acid, aspartic acid, arginine, serine and lysine. Significant amount of iron (13-50 ppm), zinc (2.5-10.5 ppm) and copper (0.18-4.03 ppm) were found in all the fishes. Among heavy metals, cadmium (0.05-0.1 ppm) was detected which is below permissible limit.
