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. ...
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 ...
Tilapia (T. nilotica) and Azolla (A. pinnata) cage farming in Laguna Lake
(Fisheries Research Society of the Philippines, 1986)
Four batches of Azolla were grown in cages in Laguna lake between 1981 to 1983. Percent increase in weight per day ranged from 35% (Feb. 24 - March 2, 1981) to 5% (May 8 - May 12, 1983.) Best growth was attained during the ...
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. ...
Occurrence of milkfish, Chanos chanos (Forsskal) eggs around Panay Island, Philippines
(The Faculty of Fisheries, Nagasaki University, 1980)
A total of 551 milkfish eggs was collected by horizontal tows with a fish larval net in the waters around Panay island during the period from April 1976 to June 1979. The maximum number obtained by a single tow was 33 eggs. ...
Influence of feeding rate and diet form on growth and survival of Nile tilapia (Oreochromis niloticus) fry
(Elsevier, 1987)
Young Nile tilapia (12 mg mean body weight and 11 mm total length) were stocked at a density of 5 fish/l in twelve 50-l aquaria filled with 30 l of tap water. They were fed pellet crumbles containing 35% crude protein at ...
Year-round spawning and seed production of the rabbitfish, Siganus guttatus
(Elsevier, 1986)
A series of experiments on the spawning and larval rearing of Siganus guttatus was conducted during a 14-month period in 1984–1985. Spawning occurred every month throughout the year, without hormonal treatment, between the ...
