Effect of varying dietary crude protein levels on spawning frequency and growth of Sarotherodon niloticus breeders
(Fisheries Research Society of the Philippines, 1983)
Four-month-old S. niloticus breeders were fed with dry pellets containing 20 to 50% crude protein in two separate experiments. Their frequency of spawning and their growth in length and weight were determined over a 16-week ...
Spawning behavior and early life history of the rabbitfish, Siganus guttatus, in the laboratory
(Elsevier, 1986)
The spawning behavior and embryonic and larval development of Siganus guttatus are described from laboratory observations. Characteristic prespawning behavior began 4 h before actual spawning: the female touched the anal ...
Effect of various salinity levels and stock manipulation methods on the survival of milkfish fry (Chanos chanos) during storage.
(Fisheries Research Society of the Philippines, 1980)
The survival and growth of milkfish (Chanos chanos ) fry stored in plastic basins at different salinity levels and stock manipulation methods without aeration and fed with hard-boiled chicken egg yolk over a period of 14 ...
Effects of temperature on behavior, growth, development and survival in young milkfish, Chanos chanos (Forskal)
(Elsevier, 1983)
Effects of three temperature treatments on activity, feeding, growth, development and survival of young milkfish (Chanos chanos) were investigated. Low temperature (<22.6°C) and hypoxial condition (<1 ppm O2) decreased ...
Biological evaluation of phytoplankton (Chlorella sp., Tetraselmis sp. and Isochrysis galbana) as food for milkfish (Chanos chanos) fry.
(Elsevier, 1984)
Phytoplankton cultures of Chlorella sp., Tetraselmis sp. and Isochrysis galbana were used alone as feed to rear separate batches of newly caught milkfish (Chanos chanos) fry (about 21 days old). Ultrastructural studies of ...
Fry-to-fingerling production of Tilapia nilotica in aquaria using phytoplankton as natural feed
(University of the Philippines at Los Baños, 1982)
Two experiments were conducted to demonstrate the efficiency of phytoplankton as natural feed in fry-to-fingerling production of Tilapia nilotica . In the first experiment, growth and survival rates of fry given a sustained ...
Effects of food ration on growth, condition factor, food conversion efficiency, and net yield of estuary grouper, Epinephelus salmoides Maxwell, cultured in floating net-cages
(Elsevier, 1982)
The effects of food ration on the growth and yield of the estuary grouper raised in floating net-cages were investigated. The optimum ration given on alternate days was 5% body weight (wet) which gave the best mean fish ...
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 ...
Dietary crude protein requirement of Tilapia nilotica fry
(University of the Philippines at Los Baños, 1982)
Tilapia fry were stocked at three per liter in wooden tank compartments or glass aquaria filled with 50 or 35 l of fresh water in three separate feeding trials. The fry were fed isocaloric practical diets containing 20, ...
Larval rearing of bighead carp, Aristichthys nobilis Richardson, using different types of feed and their combinations
(Blackwell Publishing, 1988)
The effects of different types of feed, given singly or in combination, on the growth and survival of bighead carp, Arislichlhys nobilis Richardson, larvae reared for a period of 12 weeks were determined. Growth was highest ...
