Daily amount of rotifers taken by a sea bass Lates calcarifer larvae
(Science and Technology Information Institute, 1990)
The amount of rotifers consumed by a single sea bass Lates calcarifer larva per day (R) was examined by both the direct and by the satiation-digestion methods. In the direct method, R is estimated by the number of rotifers ...
Increasing milkfish (Chanos chanos) yields in brackishwater ponds through increased stocking rates and supplementary feeding
(Asian Fisheries Society, 1990)
Brackishwater milkfish culture in the Philippines is normally practiced at fish stocking rates of 2,000-3,000 ha<sup>-1</sup> with fertilizers as the sole nutrient input. Supplementary feeding is not common. We stocked two ...
Mercury levels in the sediment, water, and selected finfishes of Laguna Lake, the Philippines
(Elsevier, 1990)
Monthly samples of sediment, water and commercially important species of fish, primarily Oreochromis niloticus and Chanos chanos , plus a few other species, were collected from the West Bay area of Laguna Lake, The Philippines ...
Organic pollution resulting from excess feed and metabolite build-up: Effect on Penaeus monodon postlarvae
(Elsevier, 1990)
Penaeus monodon postlarvae, PL, with mean weight and mean total length of 0.57 mg and 6.5 mm respectively, were stocked in aerated aquaria at 20 litre<sup>−1</sup> of seawater. They were fed minced shrimp meat at rates of ...
Improved larval survival at metamorphosis of Asian seabass (Lates calcarifer) using ω3-HUFA-enriched live food
(Elsevier, 1990)
Asian seabass (Lates calcarifer) larvae were fed Brachionus cultured on Chlorella and, as soon as ingestin was possible, different types of Artemia, i.e., nauplii of the San Francisco Bay (SFB) strain, Great Salt Lake (GSL) ...
Studies on the digestive lipases of milkfish, Chanos chanos
(Elsevier, 1990)
Milkfish grown on two natural foods were examined to determine the distribution pattern of the digestive lipases along the digestive tract and to identify the optimum condition for lipase activity. One food consisted of a ...
Survival of young rabbitfish (Siganus guttatus Bloch) under simulated transport conditions
(Blackwell Publishing, 1990)
The effect of loading density, transport duration, water temperature, and salinity on survival of young rabbitfish (Siganus guttatus Bloch) under simulated transport conditions was investigated. The rocking motion of ...
Studies on the chemical control of luminous bacteria Vibrio harveyi and V. splendidus isolated from diseased Penaeus monodon larvae and rearing water
(Inter Research, 1990)
The minimum inhibitory concentrations (MICs) and minimum bactericidal concentrations (MBCs) of 24 drugs for luminous bacteria Vibrio harveyi and V. splendidus were determined. Only chloramphenicol, sodium nifurstyrenate ...
Tissue distribution of mercury and selenium in minnows, Phoxinus phoxinus
(Springer Verlag, 1990)
The protective effect of selenium against mercury toxicity has been extensively demonstrated in a number of studies (Burke eta]. 1977; Kasuya 1976). Since mercury uptake is not always diminished by the presence of selenium ...
Interaction between test and reference populations when tilapia strains are compared by the “internal control” technique
(Elsevier, 1990)
Several strains of Oreochromis niloticus, O. mossambicus and their hybrids occur in the Philippines, and others are likely to be introduced or developed locally in the near future. Our objective was to study biological ...
