Egg size and larval size among teleosts: implications to survival potential
(Asian Fisheries Society, 1986)
A survey of the early life history characteristics of 135 teleost fishes from freshwater, marine, tropical, temperate and boreal habitats show the influence of egg size and larval size on survival potential. Marine species ...
Aeration system at the Tigbauan Research Station of the Southeast Asian Fisheries Development Center, Aquaculture Department (SEAFDEC/AQD)
(ASEAN/UNDP/FAO Regional Small Scale Coastal Fisheries Development Project, 1986)
Roots blowers are used to meet aeration requirements at the Tigbauan Research Station (TRS) of the SEAFDEC Aquaculture Department in Iloilo. Air is delivered through a system of PVC pipes and plastic tubing attached to air ...
Effects of storage on the microbial quality of slipper oysters, Crassostrea iredalei
(Asian Fisheries Society, 1986)
The effects of storage on the microbial quality of slipper oysters, Crassostrea iredalei, were examined. Oysters were stored at room temperature (24°C), under a blanket of ice (3-4 C), chilled (4-C) and frozen (-25°C) until ...
Hormonal changes accompanying sexual maturation in milkfish Chanos chanos Forsskal
(Nagoya University Corporation, 1987)
In spite of the economic importance of milkfish to the Southeast Asia, relatively little information is available on its reproductive biology and physiology. Milkfish has a prolonged juvenile phase undergoes first sexual ...
The larval and juvenile fish community in Pandan Bay, Panay Island, Philippines
(Ichthyological Society of Japan, 1986)
Long-term (1975-1977) collections of larval and juvelnile fish were made from 1) onshore, a sandy beach flanked by a coral terrace and a river mouth, and 2) 500m offshore in 30 m deep water in Pandan Bay. About 70 species ...
Typical prawn diseases - causes, prevention, and treatment
(U.P. Aquaculture Society, 1988)
Diseases of prawn in ponds are caused by microorganisn like viruses, bacteria fungi and protozoans as well as factors such as nutritional deficiency, poor pond conditions and environmental pollutants. Most of these may be ...
Prawn health in aquaculture
(U.P. Aquaculture Society, 1988)
Disease management of intensively-cultured prawns requires an understanding of physiology and disease causation. Maladies result from an interaction of the prawn, disease agents and their environment. In intensive culture, ...
Acceptability of five species of freshwater algae to tilapia (Oreochromis niloticus) fry
(International Development Research Centre, 1985)
Unialgal cultures of Oscillatoria quadripunctulata, Chroococcus dispersus, Navicula notha, Euglena elongata, and Chlorella ellipsoidea were fed to tilapia fry for 30 days. Mean weights and survival rates of the fry were ...
Nutrient flow and physicochemical profile studies of an integrated poultry-salt-Artemia-milkfish-sea bass-shrimp pond production system
(Wetteren, Belgium: Universal Press, 1987)
The physicochemical and biological parameters of an integrated flow-through poultry-salt-Artemia-milkfish-sea bass-shrimp pond production system were monitored for 6 months to determine the pattern of nutrient changes and ...
Constraints and prospects in aquaculture development.
(Nagoya University Corporation, 1987)
The development of aquaculture in developing countries of the Asia-Pacific region is constrained by inadequate seeds, diseases and other causes of mortality, lack of effective natural food and formulated feeds, problems ...
