    Culture of grey mullet, Mugil cephalus, Linnaeus in brackishwater ponds at two stocking densities 

    DD Baliao, EM Rodriguez & DD Gerochi - SEAFDEC Aquaculture Department Quarterly Research Report, 1981 - Aquaculture Department, Southeast Asian Fisheries Development Center
    The culture potential of hatchery-produced grey mullet (Mugil cephalus , Linnaeus) stocked with average weight of 3.7 g and at 2,500 (treatment I) and 3,000 (treatment II) fingerlings/ha in six 350m brackishwater ponds following the lab-ab method of culture was studied.

    Effects of increased stocking density and supplemental feeding on the production of milkfish fingerlings 

    CT Villegas & I Bombeo - SEAFDEC Aquaculture Department Quarterly Research Report, 1981 - Aquaculture Department, Southeast Asian Fisheries Development Center
    Experiments were conducted to determine the effects of increased stocking density and supplemental feeding on survival and growth of milkfish (Chanos chanos) fry to fingerling stage and also to evaluate the profitability of supplemental feeding in the milkfish fry nursery. Results showed that increased stocking density from 50 to 75 fry/m2 increased net income and is profitable. Survival was further increased through supplemental feeding with rice bran, which is cheap and easily obtainable.

    Effects of temperature on behavior, growth, development and survival of young milkfish, Chanos chanos Forsskal 

    AC Villaluz & A Unggui - SEAFDEC Aquaculture Department Quarterly Research Report, 1981 - Aquaculture Department, Southeast Asian Fisheries Development Center
    The effects of 3 temperature treatments on activity, feeding, growth, development and survival of young milkfish (Chanos chanos) were investigated under laboratory conditions. It is believed that the results may be applied to develop a land-based mass production technology in rearing milkfish fry to fingerlings.

    Gill lesions associated with acute exposure to ammonia 

    ER Cruz & GL Enriquez - SEAFDEC Aquaculture Department Quarterly Research Report, 1981 - Aquaculture Department, Southeast Asian Fisheries Development Center
    Histopathological effects of ammonia on the gills of milkfish (Chanos chanos) fingerlings were examined qualitatively.

    Effects of exogenous hormone injections on milt consistency in newly caught, wild milkfish 

    JV Juario, GF Quinitio, J Banno & M Natividad - SEAFDEC Aquaculture Department Quarterly Research Report, 1981 - Aquaculture Department, Southeast Asian Fisheries Development Center
    A study was conducted to determine the effects of single injections of human chorionic gonadotropin (HCG) and Durandron Forte 250 on sperm motility, vitality and density and also on the consistency of milt in newly caught, wild, mature milkfish (Chanos chanos). In contrast to HCG, single injections of Durandron Forte 250 were effective not only in inducing spermiation but also in maintaining newly caught mature males in good running condition for a maximum of 7 days, despite daily handling and collection of approximately 3ml milt.
