    Preservation Of Fish By Freezing And Glazing: II. Keeping Quality Of Fish With Particular Reference To Yellow Discolouration And Other Allied Organoleptic Ch.Anges On Prolonged Storage
    (Society of Fisheries Technologists (India) Cochin, 1970) Jadhav, M. G.; Magar, N. G.
    Organoleptic observations of quick, slow and bloclc frozen, glazed and stored fish were recorded at regular intervals. Glazing was renewed at intervals of four weeks. Development of yellow discolouration in the case of white pomfret was followed. Keeping quality of glazed fish was better than unglazed frozen fish. Yellow discolouration could be controlled by ascorbic acid for 4~ months and by a mixture of ~odium chloride and glucose for 5t months.

    Preservation Of Fish By Freezing And Glazing 1. Bacteriology Of Fresh, Frozen And Glazed Fish
    (Society of Fisheries Technologists (India) Cochin, 1970) Jadhav, M. G.; Magar, N. G.
    Microbiological investigation of fresh and frozen fishes such as pomfret, surmai and mackerel was carried out under various conditions of preservation. Glazing, block-freezing and preservation in gunny bag were effected. Determination of bacterial load and isolation, identification and classification of the resistant bacteria were niade. Spore-formers of Subtilis mesentericus group were found to be resistant to freezing as well as glazing by ascorbic acid, citric acid and sodium nitrite except a mixture of sodium chloride and glucose. Bacterial load was reduced to a good extent and maintained low till the end of frozen storage period

    Preliminary Observations On The Effect Of Electrical Seine On Fish Catch
    (Society of Fisheries Technologists (India) Cochin, 1970) Biswas, K. P.
    Fortysix experiments were done with the electric seine in 24 tanks with A. C. and interrupted A. C. The source of electrical energy was a 3 KW A. C. generator of water-cooled diesel engine. A control seining without applying electricity was conducted for every experiment with electric ''seine,. to have a comparison for the efficiency of electric "seine'• over control ones. Electric seine was found to have an increased catch over control seining both in numbers and in weight. Electric seine with two electrodes was found to have better effect over three electrodes. Benthic fishes like Cirrhina mrigala, Notopterus notopterus, Cyprinus carpio, Glassogobius giuris, Ophicephalus sp. and Mystus sp. were found to be more sensitive in electric "seine". Increased catch of small fishes like C. mriga/a, N. notopferus and Ophicephalus sp. has been observed in electrical "seine" in addition to larger ones.

    Further Observation On Newly Located Prawn Fishery Of Saurashtra Cost
    (Society of Fisheries Technologists (India) Cochin, 1970) Gopalan, U. K.
    The abundance of prawns in a newly located ground off Saurashtra has been described. Catch composition showed that Metapenaeus a{finis formed the bulk of the catches. Previously this species was thought to be of not much commercial importance in this region. The peak of the fishery lasted from September to November. Observations on the biology of this species showed that it occurs as an independent stock in this region. The significance of the gear employed in fishing is also emphasized.

    Preservation Of Fish By Freezing And Glazing :III.Effect Of Freezing ,Glazing And Frozen Storage On The B- Vitamins And Essential Minerals Present In The Fish Flesh.
    (Society of Fisheries Technologists (India) Cochin, 1970) Jadhav, M. G.; Magar, N. G.
    The changes occurring in moisture, thiamine, riboflavin niacin, phosphorus, iron and calcium in pomfrets, surmai and mackerel frozen, glazed with ascorbic acid. citric acid, sodium chloride & glucose and sodium nitrite and kept under frozen storage were studied upto 6 months and results reported.
