- ItemStudies On Radiation Pasteurisation Of Medium Fatty Fish III. Storage Properties Of White Pomfret(Stromateus Cinereus ) Fillets(Society of Fisheries Technologists (India) Cochin, 1972)White pomfret fillets packed under aerobic conditions had a limited shelf life of 8 days as against 10 days for samples packed under vacuum and stored at 0~2°C. Irradiation and subsequent storage of the fillets under vacuum at 0-2°C exhibited shelf lives of 30, 50 and 60 days for radiation doses of 0.1, 0.3 and 0.5 Mrad respectively in contrast to aerobically packed fillets which showed only 20, 35 and 50 days of storage life for the same levels of radiation doses and developed yellow discolouration and rancid odours.
- ItemSome Bacteria Isolated From Marine Plankton And Mud(Society of Fisheries Technologists (India) Cochin, 1972)Fiftyseven bacterial strains isolated from marine plankton and mud from the inshore waters of Cochin are described. The flora of the plankton was dominated by chromogens while mud sample& failed to produce chromogens. The different strains are divided into five arbitrary groups for the convenience of description. The flora is similar to that of Mandapam (east ccast) while it differed from the flora of Calicut (west coast) in tlic paucity of Baci!Tus· sp and other sporeformers.
- ItemSequential Analysis For Testing Quality Standard Of Fish Ham And Sausage(Society of Fisheries Technologists (India) Cochin, 1972)Fish sausages are finely ground fish flesh, either of a single species or mixed, homogenised with starch, sugar, fat, spices and preservatives, generally filled in cylindrical synthetic or natural casings and pasteurised. Similar products containing small pieces of quality fish and lard are termed "fish ham". They are highly relished products in Japan, annual consumption exceeding 2 lakh tonnes. Preliminary studies in our college have shown that they can catch a lucrative market in our country. In accepting or rejecting any lot of finished product presented for inspection usually a single sampling procedure is followed where a random sample of prescribed size from the lot is taken and analysed. If the products are mass produced, single (random ) sampling is most suitable. But when the production is on small scale, lot by lot acceptance by sequential analysis is the most convenient. This plan is economical in the sense it avoids excessive sampling losses; and is superior to any other sampling method now available since it gives the largest number of correct decisions with the smallest amount of information.
- ItemA New Observation On Large Scale Disintegration Of Eggs Of Indian Major Carps During Development(Society of Fisheries Technologists (India) Cochin, 1972)Mysterious disappearance of carp eggs from the happa in large scale during development caused considerable loss of spawn raised by induced breeding technique (Chaudhuri and Alikunhi, 1957). Panicker et a! (1969) have observed such large scale destruction of fertilised eggs by common carp, Cyprinus carpio, rupturing the egg shells by sucking from outside the happa containing eggs. But mass scale disintegration of eggs in happas within a few hours has been reported by other workers in ponds devoid of common carps indicating that some other factors are also responsible for untimely rupture of egg shells leading to disintegration of eggs in a short time. Fertilisation of eggs is accompanied by hydration of oocytes and movement of ions across the egg membrane from the surrounding media.
