Effect of salinity on the osmotic, chloride, total protein and calcium concentrations in the hemolymph of the prawn Peneaus monodon (Fabricius)
(Elsevier, 1986)1. Osmolality and chloride concentrations in the hemolymph of Penaeus monodon became stable 1 day after molting in 32 ppt, while total protein and calcium concentrations remained stable throughout the molting cycle. When ... -
Digestibility in milkfish, Chanos chanos (Forsskal): Effects of protein source, fish size and salinity
(Elsevier, 1986)The true digestibility of casein, gelatin, fish meal, defatted soybean meal and Leucaena leucocephala leaf meal was measured in 60- and 175-g milkfish (Chanos chanos Forsskal) in fresh- and seawater. The diets contained ... -
Effects of salinity on egg development and hatching of Siganus guttatus
(University of San Carlos, 1986)Experiments were conducted to determine the tolerance of Siganus guttatus eggs to salinity changes. In the first run, the female was induced to spawn spontaneously by using human chorionic gonadotropin. The fertilized eggs ... -
Biological evaluation of three phytoplankton species (Chlorella sp., Tetraselmis sp., Isochrysis galbana) and two zooplankton species (Crassostrea iredalei, Brachionus plicatilis) as food for the first-feeding Siganus guttatus larvae
(University of San Carlos, 1986)First-feeding Siganus guttatus larvae were given different species of phytoplankton (Chlorella, Tetraselmis, Isochrysis) and zooplankton (oyster trochophores, Brachionus) or a combination of both on the first day when they ... -
Effect of stocking density and duration on stunting milkfish fingerlings in ponds
(Taylor & Francis, 1986)The paper discusses the effect of stocking density and holding periods in stunting milkfish fingerlings in brackishwater ponds using twelve units of 144m2 earthen ponds. With 15, 20, and 25 fingerlings/m2 ... -
An incidence of swimbladder stress syndrome in hatchery-reared sea bass (Lates calcarifer) larvae
(Elsevier, 1986)This paper describes an incidence of swimbladder malfunction causing high positive buoyancy and mass mortality in 2-week-old sea bass (Lates calcarifer) larvae reared in an outdoor hatchery tank under conditions of high ... -
Yolk resorption, onset of feeding and survival potential of larvae of three tropical marine fish species reared in the hatchery
(Springer Verlag, 1986)This paper provides basic early life-history information on milkfish (Chanos chanos), seabass (Lates calcarifer) and rabbitfish (Siganus guttatus) which may explain in part the observed differences in their survival ... -
Immuno-response in tilapia Sarotherodon niloticus vaccinated with Edwardsiella tarda by hyperosmotic infiltration method
(Elsevier, 1986)Sarotherodon niloticus with average weight of 28.42 ± 1.87g were immunized with formalin-killed Edwardsiella tarda using the hyperosmotic infiltration method. Test fish maintained in 30 l aquaria were grouped into four ... -
Histopathological response of milkfish Chanos chanos Forsskal fingerlings to potassium permanganate
(Japanese Society of Fish Pathology, 1986)Static 96 h bioassays were conducted on milkfish fingerlings at concentrations ranging from 1.00 to 1.80 mg/l KMnO4. Histopathological analyses of gills, liver, and kidney tissues revealed significant changes ... -
The ultrastructure of the hepatocytes of the giant seaperch, Lates calcarifer (Bloch) (Pisces: Centropomidae), during starvation and refeeding with different diets.
(The Marine Biological Association of Hongkong, 1986)Three groups of immature seaperch acclimated in the laboratory on a mixed commercial pellet and minced trashfish diet were starved for 30 days. Thereafter, the first group was starved for 7 more days, the second was refed ... -
Evaluation of practical diets in the culture of the rabbitfish, Siganus guttatus (Bloch) (Pisces: Siganidae) using liver ultrastructural methods
(Elsevier, 1986)The starvation-induced ultrastructural modifications in the hepatocytes were reversed when Siganus guttatus resumed feeding on a suitable feed. The liver cells regained their structural integrity soonest when the fish was ... -
Midgut gland as monitor organ for the nutritional value of diets in Penaeus monodon (Decapoda)
(Elsevier, 1985)Midgut gland cells of Penaeus monodon postlarvae were investigated by electron microscopy after starvation and refeeding with different diets. Well nourished postlarvae could be starved for 5 days without irreversible ... -
A histological study of the hypophysial-gonadal system during sexual maturation and spawning in the milkfish, Chanos chanos (Forskal)
(Wiley-Blackwell, 1985)The pituitary gland of the milkfish, Chanos chanos, was studied at different stages of sexual maturation and spawning. Consecutive median sagittal sections were treated with a range of stains to demonstrate the different ... -
Uptake and depuration of mercury in the green mussel, Perna viridis Linnaeus (Bivalvia: Mytilidae)
(Science and Technology Information Institute, 1985)P. viridis were exposed to 3.6 ppb, and 100 ppb mercury. The mussels were also fed with algae that had been precontaminated with mercuric acetate to give a final mercury concentration of 10 ppb. Mercury bioaccumulation ... -
An evaluation of three annelids as feed ingredients in formulated diets for juvenile Penaeus monodon
(Fisheries Research Society of the Philippines, 1985)The nutritive value of two species of earthworms, Eisenia foetida and Eudrilus euginae and the marine annelid, Nereis sp. in P. monodon juvenila diets was determined in two separate experiments. Percentage weight gain and ... -
In vitro effects of fungicides on Haliphthoros philippinensis
(Blackwell Publishing, 1985)Pure cultures of the fungus Haliphthoros philippinensis isolated from infected Penaeus monodon larvae were exposed for 24 h to varying concentrations of the antifungal agents Benlate, calcium hypochlorite, clotrimazole, ... -
International study on Artemia. XXV. Factors determining the nutritional effectiveness of Artemia: The relative impact of chlorinated hydrocarbons and essential fatty acids in San Francisco Bay and San Pablo Bay Artemia
(Elsevier, 1985)Different Artemia cyst samples harvested from the San Francisco and the San Pablo Bay regions (California, U.S.A.), and suspect because of their poor nutritional performance in fish and crustacean farming, have been analysed ... -
Effect of thyroxine on growth and development in post-yolk-sac larvae of milkfish, Chanos chanos
(Elsevier, 1985)Post-yolk-sac larvae of milkfish, Chanos chanos (commonly referred to as “fry”) were collected along the shore in the Philippines. Treatment of these long, slender and transparent larvae with L-thyroxine-sodium (Eltroxin, ... -
Growth of juvenile milkfish Chanos chanos in a natural habitat
