    COMMERC[AL STUDIES ON RADIATION PRESERVATION OF FISH AND SHELL-FISH IN CANADA
    (Society of Fisheries Technologists (India) Cochin, 1975) Savagaon, K. A
    Considerable work has been carried out at Fisheries Research Board Laboratory, Halifax on radiation preservation of certain species of fish and shell-fish, on laboratory scale, results showing promise (Power e . a! 1964 A & B). These studies were followed up by testing the results under commercial conditions with the coop: ration of a local fish producer and the Atomic Energy of Canada Ltd. Haddock, two varieties of flounders (Yellow Tail flounder and American Plaice) and scallop were chosen for these experiments.

    STUDIES ON MATURATION ,SPAWINING ,FECUNDITY AND SEX RATIO IN BARBUS (PUNTIUS) SARANA (HAMILTON-BUCHANAN ) FROM LAKE KOLLERU , ANDRA PRADESH.
    (Society of Fisheries Technologists (India) Cochin, 1975) MURTY, V. SRIRAMACHANDRA
    Barbus sarana contains only one batch of mature ova in the mature ovaries to be spawned in one spawning act. It spawns during July-September. The fecundity ranges from 11,201 to 224,248 ova. There is a positive curvilinear correlation between total length and fecundity, the latter increasing with length at a rate of less than cube of length. The stock of this species from lake KoUeru appears to be more fecund than that inhabiting Loni reservoir. The sex ratio indicates that females outnumber males in all months and in larger length groups. Females appear to reach a larger length than males.

    EFFECT OF STARVATION ON THE BIOCHEMICAL COMPOSITION OF CLARIAS BATRACHUS(LINN.)
    (Society of Fisheries Technologists (India) Cochin, 1975) BANO, YAGANA
    Marked changes were observed in different chemical constituents of Clarias batrachus during starvation. The nitrogen and protein fractions showed a definite pattern of variations. The highest values of these were recorded on lOth day of starvation and thereafter values declined gradually. On the other hand, the acid soluble phosphorus exhibited a reverse trend, increasing graduaUy from the first to the 30th day of starvation. These changes have been attributed mainly to the energy and metabolic demands of the starving fish.
