An economic analysis of the modular pond system of milkfish production in the Philippines
(Elsevier, 1989)
In 1980, the annual yield of milkfish ponds in the Philippines was 800 kg/ha while the potential yield is estimated to be 2000 kg/ha. The modular pond system analyzed in this study can largely close the gap between actual ...
Acute toxicity of potassium permanganate to milkfish fingerlings, Chanos chanos
(Springer Verlag, 1989)
Potassium permanganate (KMnO<sub>4</sub>) is a strong oxidizing agent and is commonly used in aquatic systems to improve available oxygen, treat infectious diseases and parasites, detoxify fish poisons, and control algae. ...
Comparison of various water replenishment and fertilization schemes in brackishwater milkfish ponds
(Blackwell Publishing, 1989)
The study was undertaken to determine the optimum combination of the frequency of water replenishment and fertilization that can yield the highest growth, survival, and gross production of milkfish. Results indicated that ...
Tolerance level and histopathological response of milkfish (Chanos chanos) fingerlings to formalin
(Elsevier, 1989)
Static 96-h bioassays were conducted on milkfish (Chanos chanos ) fingerlings with formalin at concentrations ranging from 50 to 500 ppm. The 24-, 48-, 72-, and 96-h median lethal concentration values (LC50) were 322, 260, ...
Food preference of wild milkfish juveniles in connection with habitat and food availability
(Taylor & Francis, 1989)
Through quantitative determination of the gut content of wild milk fish (Chanos chanos) juveniles, the study aimed to evaluate the food preference of the fish in relation to its availability in the pond so that necessary ...
