    Effect of oxidation of dietary fish lipids on the quality of proteins in diet
    (Socity of Fishery Technologists (India), 1985) Devadasan, K.; Nair, P.G.V.; Antony, P.D.
    The paper reports results of a study on the effect of oxidized fish oil in the diet on the quality of dietary fish proteins. With increased oxidation of oil, digestibility and utilization of the protein registered a decrease. Oxidation of fish oil beyond a stage was found to affect the intake of diet itself and rats lost weight rapidly.

    Lipid breakdown in oil sardine (Sardinella longiceps) during frozen storage
    (Society of Fisheries Technologists (India), 1978) Nair, P.G.V.; Antony, P.D.; Gopakumar, K.; Nair, M.R.
    Sardines with (i) 6% and (ii) 10% fat content were frozen at -40 degrees C, stored at -18 degrees C after wrapping in polyethylene sheets for 180 days, and analysed at regular intervals for phospholipid breakdown, production of free fatty acids, and changes taking place in unsaturated fatty acids. Free fatty acid production was faster in (ii) as the neutral lipids contributed substantially to the production of free fatty acids, which was not the case in (i). Fatty acids most affected during storage were C20:5 and C22:6. The polyene indices decreased during storage. Both these effects were more pronounced in (ii).

    Nutritional evaluation of fish solubles
    (Society of Fisheries Technologists (India), 1986) Ammu, K.; Stephen, J.; Antony, P.D.
    this paper reports the results of a preliminary study on the biochemical composition and nutritional charactersitics of fish solubles from oil sardines (Sardinella longiceps) and white tailed pink perch (Nemipterus japonicas) ., The nutritional quality of sardine solubles has been evaluated by feeding trials using albino rats also . The studies have shown that compared to a control group of rats whose diet had casein as the sole source of protein, a group of rats in whose diet dried sardine solubles replaced half of the casein, had a noticeably higher growth rate . This higher growth rate was not prominent in the early stages of growth (4-7 weeks) . But, during later stages (7-10 weeks), solubles incorporated diet supported a distinctly higher growth rate . This effect was more pronounced in female rats (17% over the control group) compared to the male rats (4% over the control group) . Fish solubles are found to be poor sources of essential amino acids . Thus, the observed increase in growth rate is higher than the rate expected from the amino acid make up. This probably supports the view expressed by workers elsewhere that fish solubles contain some unidentified growth factors .
