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 ...
Hormone-induced spawning of cultured tropical finfishes
(IFREMER, 1990)
Commercially important tropical freshwater and marine finfishes are commonly spawned with pituitary homogenate, human chorionic gonadotropin (HCG) and semi-purified fish gonadotropins. These preparations are often administered ...
Optimum stocking density and tank size for larval rearing of the grouper, Epinephelus coioides
(Asian Fisheries Society, 1997)
The effect of stocking of stocking density and tank size on early growth and survival of grouper, Epinephelus coioides (=suillus) larvae were determined. In one experiment, larvae were stocked in 500L tanks at densities ...
Successive spawning of grouper, Epinephelus suillus (Valenciennes), in a tank and a floating net cage
(Elsevier, 1993)
Wild Epinephelus suillus (Valenciennes) were collected in 1989 to early 1990. To monitor natural spawning in captivity, 6 mature females (3.5–5.0 kg) and 4 mature males (7–12 kg) were transferred to a 4.6×4.6×2 m concrete ...
Leaf meals as protein sources in diets for milkfish Chanos chanos (Forsskal)
(Asian Fisheries Society, 1994)
The protencial of partial replacement of fish meal protein with protein indigenous leaf meals in practical diets for milkfish, Chanos chanos (Forsskal) was studied. Five isocaloric (375 kcal/100 g diet), isonitrogenous ...
Effect of season on oocyte development and serum steroid hormones in LHRHa and pimozide-injected catfish Clarias macrocephalus (Günther)
(Japanese Society of Fisheries Science, 1999)
Oocyte and blood samples were taken from gravid female catfish Clarias macrocephalus at 4-h intervals to monitor the stage of oocyte development and serum steroid hormone profiles after injection of luteinizing hormone-releasing ...
Growth and survival of Oreochromis niloticus, O. mossambicus and their F1 hybrids at various salinities
(Asian Fisheries Society, 1990)
Growth and survival of Oreochromis niloticus, O. mossambicus, and their F<sub>1</sub> hybrids were studied at various salinities (0-32 ppt) in net cages inside 12-tonne concrete tanks after acclimation. Growth, measured ...
Growth response and carcass composition of red tilapia fry fed diets with varying protein levels and protein to energy ratios
(Asian Fisheries Society, 1991)
An 8-week feeding experiment was conducted with red tilapia (Oreochromis ) fry of 0.160 plus or minus 0.035 g initial weight. Twelve diets of 4 protein levels (25, 30, 35 and 40%) and 3 protein to energy (P/E) ratios (111, ...
Enrichment of live food with essential fatty acids and vitamin C: effects on milkfish (Chanos chanos) larval performance
(Elsevier, 1998)
The effects of essential fatty acids (EFA) and vitamin C-enriched live food on growth, survival, resistance to salinity stress and incidence of deformity in milkfish larvae reared in tanks were investigated. Larvae were ...
Studies on the nursery rearing of seabass, Lates calcarifer (Bloch) fry in illuminated floating net cages
(Ministry of Agriculture and Water; King Abdulaziz City for Science and Technology; Riyadh Chamber of Commerce and Industry, 1994)
The feasibility of rearing seabass, Lates calcarifer, fry for fingerling production in illuminated floating nursery cages was determined. In experiment 1, seabass fry of 20.0 mm mean TL were stocked at 600 and 1200 in 1 ...
