Gill lesions in Nile tilapia Oreochromis fingerling associated with acute malathion poisoning.
(Science and Technology Information Institute, 1994)
The hispathological changes in gills of Nile tilapia, Oreochromis niloticus, fingerlings exposed to 5.3 mg/l (96-h LC50) malathion are described. These changes include hypertrophy of epithelial cells after 3 h, epithelial ...
Reproductive performance of four red tilapia strains in different seed production systems
(Society of Israeli Aquaculture and Marine Biotechnology, 1996)
The reproductive efficiency of one Thai red tilapia strain (NIFI) and three genetically diverse Philippine red tilapia strains (BFS, FAC, and PF) were compared. Breeders from each strain were stocked separately in land-based ...
Utilization of feed and rice straw compost for milkfish, Chanos chanos, production in brackishwater ponds
(Blackwell Publishing, 1991)
The study was undertaken to determine the effect of 0, 25, 50 and 75% replacement of organic matter in the feed with rice straw compost on milkfish (Chanos chanos) growth and production. Treatments have similar organic ...
Physico-chemical characteristics and pathogenicity of Vibrio Parahaemolyticus-like bacterium isolated from eye lesions of Chanos chanos (Forsskal) juveniles
(Fisheries Research Society of the Philippines, 1991)
Vibrio parahaemolyticus-like bacteria were isolated from eye lesions of milkfish juveniles. The tolerance of the typical isolate to various temperature, pH and salinity levels was tested. Pathogenicity tests done via both ...
Nursery rearing of Penaeus monodon (Fabricius) using suspended (hapa) net enclosures installed in a pond
(Elsevier, 1993)
The use of suspended (hapa) nets as nursery enclosures for shrimp fry was tested. In the first trial, four stocking densities (72, 144, 288, and 432 fry m<sup>−3</sup>) of P. monodon fry (PL<sub>20</sub>, body weight = 8 ...
Gonad development of Placuna placenta Linnaeus fed Isochrysis galbana Parke, Tetraselmis tetrahele (G.S. West) Butch, or their combination
(Elsevier, 1992)
A study was conducted to determine a suitable algal diet for the window-pane oyster, Placuna placenta Linnaeus, during gonad development. Sexually immature P. placenta (70 mm shell height) were fed Isochrysis galbana Parke, ...
Suitability of different formalin-containing fixatives for the eggs of freshwater Asian catfish Clarias macrocephalus (Gunther)
(Society of Israeli Aquaculture and Marine Biotechnology, 1991)
The suitability of different formalin-containing fixatives was tested for the eggs of the catfish (Clarias macrocephalus) by comparing the osmotic pressure of several fixatives with catfish plasma and measuring the size ...
Notes on the completion of the life cycle of Penaeus japonicus in captivity in the Philippines
(Science and Technology Information Institute, 1991)
Penaeus japonicus nauplii from wild spawners were reared up to the early postlarval stage (PL20) in 12-t concrete tanks. A survival rate of 13-15% was obtained. Hatchery-reared postlarvae were restocked in concrete tanks ...
Quantitative dietary requirements of postlarval tiger shrimp, Penaeus monodon, for histidine, isoleucine, leucine, phenylalanine and tryptophan
(Elsevier, 1999)
The quantitative requirements of postlarvae Penaeus monodon for essential amino acids were determined through a series of feeding experiments. Test diets contained casein–gelatin as natural proteins supplemented with ...
Culture of finfish in netcages
(Society of Aquaculture Engineers of the Philippines, Inc., 1998)
This report consists of two parts, the first deals on the cage culture of grouper, and the second on cage culture of tilapia. The culture of groupers is done in netcages set in marine waters, while tilapia is raised in ...
