The influence of broodstock nutrition on the reproductive performance and egg and larval biochemical composition of the mangrove red snapper, Lutjanus argentimaculatus, for its sustainable aquaculture production
(Japan International Research Center for Agricultural Sciences, 2002)
Induction of sex inversion in juvenile grouper, Epinephelus malabaricus, (Bloch and Schneider) by bi-weekly injections of 17 alpha-methyltestosterone
(Society for the Study of Endocrinology, Metabolism and Reproduction, University of Hong Kong, 1989)
Groupers (Family Serranidae) are protogynous hermaphrodites. Natural sex inversion of different species occurs at 2-11 years of age . The scarcity of wild mature males and the length of time to change sex underline the ...

Evaluation of different live food organisms on growth and survival of river catfish, Mystus nemurus (C&V) larvae
(European Aquaculture Society, 2001)
Mystus nemurus is one of the most commercially important freshwater fish in Malaysia. Even though artificial breeding or reproduction of M. nemurus is done in private hatcheries around Peninsular Malaysia, inadequate seed ...
Food consumption of seaperch, Lates calcarifer, in captivity.
(Pudoc, 1989)
In the Philppines, feeds and constitutes some 70% of the total capital cost in aquacultural, which illustrates the central ipmortance of such inputs and at the same time justifies a major research effort to study the field ...
Status of breeding and larval rearing of groupers
(Network of Aquaculture Centres in Asia-Pacific, 2002)
Attempts to breed groupers in captivity started about four decades ago. Ukawa et al. (1966) described the successful fertilization and embryonic development of the red grouper Epinephelus akaara. Fueled by the high market ...
Growth and survival of Nile tilapia fingerlings in net cages without supplemental feed in Laguna Lake, Philippines
(Asian Fisheries Society, 1986)
Oreochromis niloticus fingerlings were stocked at densities of 50, 100, 150 and 200 fish/m super(2) in fixed net cages in Laguna Lake, Philippines. These were reared without supplemental feed on 1 April-30 July 1980, 5 ...
Toxicity of four botanical insecticides to fingerlings of Nile tilapia and common carp
(Asian Fisheries Society, 1994)
Static bioassay test was done to determine the toxicity of four botanical insecticides (BI) - Blumea balsamifera leaves, Vitex negundo leaces, Azadirachta indica seeds, Tinospora rumphii stems to fingerlings (0.8 - 1.5g) ...
The effect of various levels of protein, fat carbohydrates and energy on growth, survival and body composition of Chanos chanos fingerlings
(Center for Agricultural Publishing and Documentation, Pudoc Wageningen, 1989)
Rice and fish are staple foods in the Philipines as well as in other parts of Southeast Asia, where calorie/protin malnutrition is a serious probem. Milkfish, (Chanos chanos) is well-liked by the masses and, therefore, ti ...
Use of internal reference population for growth rate comparison of tilapia strains. I. In a crowded environment
(1990)
This paper reports an experimental design in which reference fish are included in each replicate to provide internal statistical control over environmental variation. Growth of 10 full-sib families from each of 3 strains ...

Improved hatchery rearing techniques for the Asian catfish, Clarias macrocephalus (Gunther)
(European Aquaculture Society, 1995)
The Asian catfish, Clarias macrocephalus, is a popular freshwater foodfish in the Philippines. However, grow-out farming of this species is hampered by the lack of juveniles for stocking. A series of experiments on zooplankton ...
