Effect of varying crude protein levels on spawning frequency and growth of Sarotherodon niloticus breeders
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)
Four-month-old S. niloticus breeders were fed with dry pellets containing 20-50% crude protein and the frequency of spawning involving removal of egg from the mouthbrooding females and growth were determined. When the diets ...
Acute toxicity of un ionized ammonia to milkfish (Chanos chanos) fingerlings
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)
The acute toxicity of un-ionized ammonia to milkfish (Chanos chanos) fingerlings was determined using a static bioassay system. Median lethal concentrations found show that milkfish fingerlings have a high tolerance to ...
Effects of 2-phenoxy ethanol and MS-222 on milkfish fingerlings (Chanos chanos) as anaesthetic agents
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)
An experiment was undertaken in order to determine an adequate anaesthetic and optimum concentrations for use in the handling of fingerling milkfish (Chanos chanos). The compounds 2-phenoxy ethanol and MS-222 were investigated. ...
Effects of exogenous hormone injections on milt consistency in newly caught, wild milkfish
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)
A study was conducted to determine the effects of single injections of human chorionic gonadotropin (HCG) and Durandron Forte 250 on sperm motility, vitality and density and also on the consistency of milt in newly caught, ...
Effects of temperature on behavior, growth, development and survival of young milkfish, Chanos chanos Forsskal
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)
The effects of 3 temperature treatments on activity, feeding, growth, development and survival of young milkfish (Chanos chanos) were investigated under laboratory conditions. It is believed that the results may be applied ...
Dietary crude protein requirement of Tilapia nilotica fry
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)
To determine growth and survival of Tilapia nilotica fry fed formulated practical dry diets with varying crude protein levels, fish were subjected to 3 seperate feeding trials. Isocaloric practical diets containing 20, 25, ...
A comparative study of various extenders of milkfish, Chanos chanos (Forsskal) sperm preservation
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
Four chemical extenders in 7 different concentrations (potassium chloride, sodium chloride, glucose, sodium citrate, Ringer s solution, cow serum and milkfish (Chanos chanos) serum) were compared in the preservation of ...
Polyculture of milkfish (Chanos chanos) and mud crab (Scylla serrata) at two stocking densities
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1980)
Mud crabs (Scylla serrata) were cultured singly and in combination with milkfish (Chanos chanos) to compare growth, survival and production rates. Net production of crab was higher in polyculture than monoculture, but the ...
Culture of grey mullet, Mugil cephalus, Linnaeus in brackishwater ponds at two stocking densities
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)
The culture potential of hatchery-produced grey mullet (Mugil cephalus , Linnaeus) stocked with average weight of 3.7 g and at 2,500 (treatment I) and 3,000 (treatment II) fingerlings/ha in six 350m brackishwater ponds ...
Effects of increased stocking density and supplemental feeding on the production of milkfish fingerlings
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)
Experiments were conducted to determine the effects of increased stocking density and supplemental feeding on survival and growth of milkfish (Chanos chanos) fry to fingerling stage and also to evaluate the profitability ...
