Studies on semi-intensive seed production of grouper (Epinephelus coioides)
(Australian Centre for International Agricultural Research, 2004)
This study was conducted to improve the hatchery survival of <i>Epinephelus coioides</i> by verifying and incorporating laboratory-scale experimental results to a hatchery-scale operation. Nine units of 200 m<sup>2</sup> ...
Molluscicidal activity of tobacco dust against brackishwater pond snails (Cerithidea cingulata Gmelin)
(Elsevier, 1998)
Toxicity tests on the effect of tobacco dust against brackishwater pond snails (Cerithidea cingulata Gmelin) of various stages or size ranges were conducted under controlled laboratory conditions. The 72-h LC<sub>50</sub> ...

Digestive enzyme activity in developing grouper (Epinephelus coioides) larvae
(Australian Centre for International Agricultural Research, 2004)
This study was undertaken to determine the activities of alkaline and acid type proteases [proteinases], α-amylase, lipase [triacylglycerol lipase], trypsin, chymotrypsin, leucine aminopeptidase [cytosol aminopeptidase], ...

Development of formulated feeds for grow-out culture of grouper (Epinephelus coioides) - tank and field studies
(Australian Centre for International Agricultural Research, 2004)
The objectives of this study were to compare the performance of a Southeast Asian Fisheries Development Centre (SEAFDEC) formulated diet with a commercial feed for growout culture of grouper and to transfer technology on ...
Susceptibility of hatchery-reared snubnose pompano Trachinotus blochii to natural betanodavirus infection and their immune responses to the inactivated causative virus
(Elsevier, 2011)
Mass mortality of snubnose pompano Trachinotus blochii fry exhibiting dark coloration, anorexia, and abnormal swimming behavior was recently documented at the hatchery of the Aquaculture Department of the Southeast Asian ...
Culture of invertebrates as food organisms for village-level fish hatcheries
(South China Sea Fisheries Development and Coordinating Programme, 1982)
A review is presented of some practical methods that may be applied by fish farmers in producing food organisms for fish and prawn hatcheries. Organisms involved in the discussion include Moina, chironomid larvae, mosquito ...
The length-weight relationship, food habits and condition factor of wild juvenile milkfish in Sri Lanka
(Elsevier, 1986)
Wild juvenile milkfish (Chanos chanos) were obtained from Negombo lagoon in September 1984. Thirty-one specimens (92–186 mm FL) had a fork length-body weight relationship of log W = −5.6083 + 3.2598 log L. These fish were ...
Collection of naturally-spawned milkfish eggs in floating cages
(Asian Fisheries Society, 1986)
Natural spawnings of milkfish from floating cages were obtained from different stocks of 5-7 year-old milkfish in 1980, 1981, 1983 and 1985. The maximum number of eggs collected in 1980, using a series of 1-m diameter ...
Seminal plasma composition, sperm motility, and milt dilution in the Asian catfish Clarias macrocephalus (Gunther)
(Elsevier, 1999)
Ionic composition of the seminal plasma and factors that initiate sperm motility in the freshwater Asian catfish Clarias macrocephalus, were examined to develop an artificial seminal plasma (ASP) that can be used to dilute ...
The effects of water hardness on the hatching and viability of silver carp (Hypophthalmichthys molitrix) eggs
(Elsevier, 1987)
An investigation was conducted to establish water hardness concentration for optimum hatching of silver carp (Hypophthalmichthys molitrix) eggs. Eggs were incubated for 19 h at 26.5°C at six levels of water hardness: 100, ...
