A guide to induced spawning and larval rearing of milkfish Chanos chanos (Forsskal)
(Aquaculture Department, Southeast Asian Fisheries Development Center; International Development Research Centre, 1982)
The techniques for the artificial propagation of milkfish (Chanos chanos ) developed at SEAFDEC are presented. These include: 1) capture and transport of spawners; 2) determination of sex and weight and maturity of fish; ...
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, ...

Abstracts of the 17 papers presented at the conference are cited individually in this issue.
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, ...
Acid sulfate soils and their management for brackishwater fishponds
(Aquaculture Department, Southeast Asian Fisheries Development Center; International Development Research Centre; Island Publishing House, Inc., 1984)
The major problems of fishponds build on acid sulfate soils are low pH; ionic imbalance and toxic levels of aluminum, iron, and sulfate; deficiency of phosphorus and poor response to fertilizer application; slow and poor ...
Gonadal development and induced breeding of captive milkfish in Taiwan
(Aquaculture Department, Southeast Asian Fisheries Development Center; International Development Research Centre; Island Publishing House, Inc., 1984)
The induced breeding of milkfish (Chanos chanos ) has been attempted by many institutes in the Philippines, Taiwan, Tahiti, Indonesia, and Hawaii. So far, a few successful trials have been achieved only in the Philippines ...
