    Nutritional Profile and Heavy Metal Content of Cultured Milkfish (Chanos chanos)
    (Society of Fisheries Technologists(India), 2016) Murthy, L.N.; Padiyar, P.A.; Rao, B.M.; Asha, K.K.; Jesmi, D.; Girija, P.G.; Prasad, M.M.; Ravishankar, C.N.
    Nutritional profile of fresh cultured milkfish (Chanos chanos) revealed that the fish had good quantity of protein, amino acids and poly-unsaturated fatty acids. Essential amino acids formed 49.49% of the total amino acids of milkfish meat. Leucine (8%), lysine (7.3%), phenyl alanine (6.7%) and histidine (6.1%) were the predominant essential amino acids. Glutamic acid (18.2%) was the dominant nonessential amino acid. The fish was rich in unsaturated fatty acids (50.74%) of which mono unsaturated fatty acids (MUFA) and poly unsaturated fatty acids (PUFA) constituted 34.47 and 16.27%, respectively. The predominant MUFA, PUFA and saturated fatty acids were oleic acid C18:1 (26.1%), linoleic acid C18:2 (10.9%) and palmitic acid C16:0 (29.82%). Heavy metals such as zinc, copper, cadmium, cobalt, mercury and lead in different body organs of cultured milkfish were within the acceptable limit. The cultured milkfish can be considered as important fish for human nutrition.

    Organochlorine Pesticides, Polychlorinated Biphenyls and Heavy Metals Residues in Myctophids off South West Coast of India
    (Society of Fisheries Technologists(India), 2016) Sankar, T.V.; Baby, L.; Anandan, R.
    Though myctophids are widely distributed in the Indian oceanic waters and contribute to a large proportion of the deep-sea fish biomass, the information regarding the presence of lipophilic chemical contaminants and heavy metals in these lipid-rich lantern fishes are relatively scanty. Analyses on the occurrence of heavy metals, organochlorine (OCPs) and polychlorobiphenyls (PCBs) in myctophids from Indian waters showed presence of organochlorine pesticides in Diaphus watasei, Diaphus luetkeni and Myctophum obtusirostre. The prominent pesticides detected in the fish tissue include endrin, dieldrin, heptachlor epoxide, α-BHC and heptachlor. Dieldrin and heptachlor epoxide were detected in M. obtusirostre while DDT isomers in D. luetkeni. The total PCB levels followed the order D. luetkeni> D. watasei>M. obtusirostre and 2, 2’, 3’, 4, 5 – pentachlorobiphenyl and 2, 3, 3’, 4’, 6- pentachlorobiphenyl. Trace metals (Fe, Zn, Cu and Mn) Composition is comparable with other fish species reported and followed the order D. luetkeni> M. obtusirostre> D. watasei. Results showed that POPs and heavy metal levels in myctophid species studied were much below the regulatory limits.
