    Fatty Acid Profile of Yellowfin Tuna Eye (Thunnus albacares) and Oil Sardine Muscle (Sardinella longiceps)
    (Society of Fisheries Technologists(India), 2016) Renuka, V.; Anandan, R.; Suseela, M.; Ravishankar, C.N.; Sivaraman, G.K..
    In the present study, fatty acid profile of yellowfin tuna eye (YFTE) was investigated. Proximate analysis of YFTE revealed the presence of high fat content (12.0%) and moderate protein content (10.2%). A comparison was made between the fatty acid composition of YFTE and sardine oil. Higher poly unsaturated fatty acid content was found in YFTE (48.8%) compared to oil sardine (30.0%). Ratio of docosahexaenoic acid (DHA) content to the total fatty acids of YFTE was 36.72% which was higher compared to oil sardine (8.67%). However, EPA content of oil sardine was higher (16.8%) than YFTE (7.07%). DHA/EPA ratio and n-3/n-6 ratio of YFTE were 5.25 and 8.97 respectively. Palmitoleic acid was the principal mono unsaturated fatty acid (MUFA) present in YFTE and oil sardine. The present study revealed that yellow fin tuna eye could be a potential source of omega-3 fatty acids.

    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.
