Ipil-ipil leaf meal as supplemental feed for T. nilotica in cages
(Fisheries Research Society of the Philippines, 1980)
Tilapia nolotica fingerlings were grown to marketable size in cages in Laguna Lake at a stocking density of 150/m super(2). Those given supplemental feed of ipil-ipil leaf meal at varying levels showed faster growth compared ...
An incidence of swimbladder stress syndrome in hatchery-reared sea bass (Lates calcarifer) larvae
(Elsevier, 1986)
This paper describes an incidence of swimbladder malfunction causing high positive buoyancy and mass mortality in 2-week-old sea bass (Lates calcarifer) larvae reared in an outdoor hatchery tank under conditions of high ...
The milkfish seed resources survey in Sri Lanka: Status, problems and recommendations
(Ministry of Fisheries and Aquatic Resources, Sri Lanka, 1986)
A summary is provided of information concerning the milkfish (Chanos chanos) seed resources of Sri Lanka, highlighting problems related to seed collection. Various recommendations are made to overcome these problems and ...
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 ...
