On the visual feeding of milkfish larvae and juveniles in captivity
(The Japanese Society of Scientific Fisheries, 1980)
Feeding of milkfish (Chanos chanos) larvae and juveniles on Artemia nauplii in captivity was observed. The retinae of the larvae were observed histologically. Milkfish larvae could not take food in the dark. The juveniles ...
Changes in the length and weight of milkfish, Chanos chanos, larvae preserved in formalin
(Fisheries Research Society of the Philippines, 1980)
Shore-caught milkfish fry (late postlarvae) and artificially-bred, laboratory-reared larvae (0-to 20-day old) were preserved in 5% and 10% freshwater-and/or seawater-formalin solutions after measuring their initial weights ...
Acute toxicity of un-ionized ammonia to milkfish (Chanos chanos) fingerlings
(Fisheries Research Society of the Philippines, 1981)
The acute toxicity of un-ionized ammonia to milkfish (Chanos chanos) fingerlings was determined using a static bioassay system. The 24-, 48-, 72-, and 96-hr LC<sub>50</sub> values were calculated at 25.74 ppm NH<sub>3</sub>-N ...
Effects of increased stocking density and supplemental feeding on the production of milkfish fingerlings
(Fisheries Research Society of the Philippines, 1982)
Experiments were conducted in twelve 144 sq. m. brackishwater ponds at Leganes Research Station, SEAFDEC, to determine the effect of increased stocking density and supplemental feeding on milkfish fingerling production. ...
Some histological observations on the opaque eyes of milkfish Chanos chanos Forskal
(Fisheries Research Society of the Philippines, 1983)
In a study on energy-protein requirements of milkfish fingerlings using semi-purified diets, several gross observations were made on individual milk-fish such as fin and tail rot, yellowish coloration of the abdomen, opacity ...
Culture experiments on the harpacticoid copepod, Tisbintra elongata Mori, and evaluation of that species as a food organism for milkfish larvae
(Faculty of Fisheries, Kagoshima University, 1980)
The mass culture of the harpacticoid copepod, Tisbintra elongata, indigenous to Panay Island were conducted, feeding them on several kinds of food materials. Salinity tolerance as physiological parameter was also examined. ...
The skull of milkfish, Chanos chanos Forsskal
(Japanese Society of Systematic Zoology, 1980)
The skull of the milkfish, C. chanos, is described so that it may be used as a tool in identifying the effect of artificial propagation in terms of skeletal malformations.
Feed preference of milkfish (Chanos chanos Forsskal) fry given different algal species as natural feed
(Elsevier, 1986)
Acclimated milkfish fry (mean wet weight, 6.0 mg) were fed with unialgal cultures of five species of freshwater algae: Oscillatoria quadripunctulata, Chroococcus dispersus, Navicula notha, Euglena elongata and Chlorella ...
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. ...
A collecting gear for naturally-spawned milkfish (Chanos chanos Forsskal) eggs in circular floating net cages
(Elsevier, 1988)
A collecting gear for naturally-spawned milkfish (Chanos chanos Forsskal) eggs in circular floating net cages is described. The gear has been shown to be effective in collecting large numbers of eggs. The collecting gear ...
