Effects of dietary l-tryptophan on the agonistic behavior, growth and survival of juvenile mud crab Scylla serrata
(Elsevier, 2010)
The reduction of the survival of mud crab during culture has been largely attributed to aggressive encounters and cannibalism. In some crustaceans, suppressed aggression is linked to increased concentration of circulating ...
Use of metaldehyde as a molluscicide in semi-commercial and commercial milkfish ponds
(Elsevier, 1998)
The effect of metaldehyde on brackish water pond snails, Cerithidea cingulata, was tested in 250 m2 ponds, and in semi-commercial and commercial milkfish ponds. The field trials were conducted at three locations, namely ...
Growth of juvenile Asian seabass, Lates calcarifer, fed varying carbohydrate and lipid levels
(Elsevier, 1997)
Growth performance of juvenile seabass (initial mean body weight, 0.90 ± 0.04 g) fed varying carbohydrate and lipid levels were determined using practical diets in a 2 × 3 factorial experiment. Two carbohydrate levels (15 ...
Enhancing nonspecific immune response of grouper, Epinephelus coioides using levamizole as immunostimulant
(University of the Philippines in the Visayas, 2008)
The use of levamisole as an alternative approach to disease prevention and control has been resorted to in aquaculture. Its immunomodulatory effect in several fish species is well documented but its effect on grouper, ...
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.
Induction of sex inversion in juvenile grouper, Epinephelus suillus, (Valenciennes) by injections of 17α-Methyltestosterone
(The Ichthyological Society of Japan, 1994)
Four groups of two-year old juvenile groupers (Epinephelus suillus), each with 8-9 individuals of mean body weight (BW) 1.2 kg, were treated with 17α-methyltestosterone (MT). MT was injected intramuscularly within the range ...
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 ...
