    (Central Institute of Fisheries Technology, Cochin, India, 2015) Ajeeshkumar, K.K.; Visnu, K.V.; Remyakumari, K.R.; Navaneethan, R.; Asha, K.K.; Ganesan, B.; Chatterjee, N.S.; Anandan, R.; Suseela Mathew
    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.

    Protective Effects of Echinorhinus brucus Liver Oil against Induced Inflammation and Ulceration in Rats
    (Central Institute of Fisheries Technology, Cochin, India, 2015) Vishnu, K.V.; Ajeeshkumar, K.K.; Asha, K.K.; Remyakumari, K.R.; Ganesan, B.; Anandan, R.; Chatterjee, N.S.; Suseela Mathew
    Anti-inflammatory and anti-ulcer activities of Bramble shark (Echinorhinus brucus) liver oil were examined in rats. The oil showed significant proportion of n-3 polyunsaturated fatty acids (PUFAs), the percentages of EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) being 16 and 18% respectively. The study also revealed that liver oil had a very favourable n3:n6 ratio of 4.7. Oral administration of shark liver oil at 1g kg-1 concentration significantly attenuated the formalin-induced paw edema in experimental rats. It exerted potent anti-ulcer effect against acid-ethanol mixturemediated lesion formation in the rat gastric mucosa.
