(1987)
An account is given of fish disease problems facing the aquaculture industry in the Philippines. The Laguna de Bay fish kills that occurred in December 1985 and February 1986, involving epizootic ulcerative syndrome of ...
Selection, transport and acclimation of prawn fry
(U.P. Aquaculture Society, 1988)
The most important criterion among many used by operators for choosing poostlarvae to stock in ponvds, is the stage of development. THe stages considered suitable for stocking (about PL<sub>20</sub>) can be identified by ...
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, ...
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 ...
An integrated semi-intensive shrimp and livestock system in the Philippines.
(Asian Fisheries Society, 1986)
The development of shrimp (Penaeus monodon) production system integrated with livestock was undertaken at the Sycip Plantation Inc., Negros Orienta, Philippines, as a result of crop diversificstion efforts in the province. ...
