Acute toxicity of un ionized ammonia to milkfish (Chanos chanos) fingerlings
The acute toxicity of un-ionized ammonia to milkfish (Chanos chanos) fingerlings was determined using a static bioassay system. Median lethal concentrations found show that milkfish fingerlings have a high tolerance to ammonia and it is unlikely that levels as high as those employed for the acute exposure would be found to occur under natural conditions. Although the threat of acute toxicological effects induced by ammonia are remote, such conditions might be encountered in stressed natural environments or in heavily loaded aquaculture systems.

Lactate dehydrogenase isozyme patterns during the development of milkfish, (Chanos chanos (Forskal)) Requintina, Pura D.; Engle, L. M.; Benitez, Lita V. (University of the Philippines at Los Baños, 1981)Polyacrylamide disc gel electrophoresis was done to determine the lactate dehydrogenase (LDH) isozyme patterns for fry (5-3 mg), fingerling (6-12 g), pond-size (150-250 g) and adult (6-9 kg) milkfish. The patterns were ...
