Aeromonas hydrophila associated with ulcerative disease epizootic in Laguna de Bay, Philippines
(Elsevier, 1987)
Aeromonas hydrophila was consistently associated with necrotic ulcers and lesions in mudfish/snakehead (Ophiocephalus striatus), Thai catfish (Clarias batrachus), crucian carp (Carassius carassius) and goby (Glossogobius ...
Depuration of molluscs
(Philippine Council for Agriculture, Forestry and Natural Resources Research and Development; Bureau of Fisheries and Aquatic Resources, 1987)
The experimental system put up at SEAFDEC [Southeast Asian Fisheries Development Center; Philippines] consisted of six rectangular (96 x 196 x 42 cm) fiberglass-coated tanks made of marine plywood. It can depurate about ...
Tilapia hatchery and nursery systems: Operation and management
(Philippine Council for Agriculture, Forestry and Natural Resources Research and Development; Bureau of Fisheries and Aquatic Resources; Aquaculture Department, Southeast Asian Fisheries Development Center, 1987)
The successful and profitable production of Tilapia nilotica in ponds or cages is predominantly influenced by the environment and hereditary traits of the stock. Therefore, stocking of high quality fingerlings is a major ...
The effects of temperature and starvation on the ultrastructure of the hepatocytes of seaperch fingerlings, Lates calcarifer (Bloch).
(Elsevier, 1987)
The hepatocytes of seaperch fingerlings reared on trashfish at constant water temperatures of 20 and 35°C were examined through electron microscopy and compared with those of controls fed identical diet or deprived of food ...
The economics of retarding milkfish growth for fingerling production in brackishwater ponds
(Elsevier, 1987)
Two experiments were conducted to measure the economic viability of retarding milkfish growth (stunting) in brackishwater ponds. In the first experiment, 2-month-old fish were reared for 6 months in ponds with initial ...

(Springer Verlag, 1987)
The occurence and distribution of milkfish larvae (∼3–17 mm TL) off western Panay Island, Philippines are reported based on 594 plankton net tows made in April and May 1980. Forty-two tows yielded 44 larvae, together with ...
The effects of iron compounds on the virulence of Vibrio anguillarum in Japanese eels and ayu
(Japanese Society of Fish Pathology, 1987)
When Japanese eels (Anguilla japonica) were injected intramuscularly (IM) with ferric ammonium citrate (FAC) at a sublethal dose of 10 µg/g and followed by IM-injection with various doses of Vibrio anguillarum, FAC injection ...
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 ...
Responses of intermolt Penaeus indicus to large fluctuations in environmental salinity
(Elsevier, 1987)
The osmotic and chloride regulation by 5- to 10-g intermolt Penaeus indicus was investigated by abruptly changing medium salinity from seawater (32 ppt) to test salinities of 8, 20, 32 (control) or 40 ppt. Hemolymph samples ...
Carbohydrate requirements of Penaeus monodon (Fabricius) juveniles
(Elsevier, 1987)
P. monodon juveniles with an initial mean weight of 0.62 g were fed isonitrogenous (45%) and isolipidic (10%) semi-purified diets containing 10, 20 and 30% trehalose, sucrose and glucose for 56 days. Shrimp fed the diet ...
