Problems encountered in the implementation of a community-based fishery resources management project
(International Center for Living Aquatic Resources Management, 1994)The article highlights the SEAFDEC Aquaculture Department's (Philippines) Community-based Fishery Resource Management Project activities. Several problems encountered in project implementation and the suggested ways in ... -

(The Economic Society of Thailand, 1993) -
Hormonal, environmental, and dietary manipulation of milkfish broodstock to enhance egg production
(International Foundation for Science, 1993)The insufficient supply of milkfis fry severely limits the expanion of milkfish aquaculture. While natural spamning and hatchery production of milkfish fry have been attained recently, there is sitll a need to incease egg ... -
Pond culture of mud crab (Scylla serrata): an economic analysis.
(1992)The study compares the profitability of mud crab pond culture with existing crab fattening practices in Iloilo, Philippines. Monoculture of Scylla serrata at stocking densities of 5,000, 10,000, 15,000 and 20,000 pcs/ha ... -
Metabolism of cysteine to taurine by rat hepatocytes.
(Plenum Press, 1992)During the past two decades, many investigators have assumed that the major locus of regulation of cysteine catabolism is the partitioning of cysteinesulfinate between its decarboxylation and transamination pathways. Hepatic ... -
Studies on the sources of luminescent Vibrio harveyi in Penaeus monodon hatcheries
(Asian Fisheries Society, Fish Health Section, 1992)One of the major problems in the otherwise highly successful Penaeus monodon hatchery industry in the Philippines is the occurrence of luminescent bacterial disease due to Vibrio harveyi. The possible sources of the bacteria ... -
Mangrove conversion and brackishwater pond culture in the Philippines
(Asian Wetland Bureau; Protected Areas and Wildlife Bureau, 1992)Around 50% of mangrove loss in the Philippines can be traced to brackishwater pond construction. The decrease in mangroves from 450 000 ha in 1920 to 132 500 ha in 1990 has been accompanied by expansion of culture ponds ... -
Aeromonas hydrophila in the epizootic ulcerative syndrome (EUS) of snakehead, Ophicephalus striatus, and catfish, Clarias batrachus: quantitative estimation in natural infection and experimental induction of dermo-muscular necrotic lesion
(1992)Snakehead (Ophicephalus striatus) and catfish (Clarias batraclus) with the Epizootic Ulcerative Syndrome (EUS) were sampled for bacteria. Total bacterial counts of skin and muscle/dermal lesions revealed mean colony forming ... -
Prawn/shrimp culture industry in the Philippines
(Elsevier, 1992)The Philippines is an archipelago of more than 7,100 islands with 17,460 km of coastline, including mangrove forests which covered about 450,000 ha in the 1920s. Coastal aquaculture began a few centuries ago when earthen ... -
The use of chemotherapeutic agents in aquaculture in the Philippines
(Asian Fisheries Society, Fish Health Section, 1992)Chemotherapeutants are widely used to treat diseases of fish, specifically shrimp and aquarium fishes in the Philippines. The most commonly treated diseases are luminous vibriosis, filamentous bacterial disease, shell ... -
Toxicity of rotenone to milkfish, Chanos chanos, and tilapia, Oreochromis mossambicus
(Asian Fisheries Society, Fish Health Section, 1992)Milkfish (Chanos canos) and tilapia (Oreochromis mossambicus) were exposed to varying concentrations of rotenone (95-98% active ingredient) to determine the median lethal concentration (LC50). The 1, 6, 12, 24, ... -
Fate and effects of water-borne heavy metals in Penaeus monodon
(European Aquaculture Society, 1991)Heavy metals impair the aquaculture of shrimps and the quality of shrimp products. Some heavy metals occur in high amounts particularly in the hepatopancreas and the antennal gland (Gibson and Barker, 1979). This study was ... -
Modular method of rearing milkfish with artificial feed.
(Asian Fisheries Society. AFS Spec. Publ. 5, 1991)The study was conducted to determine the effectiveness of a practical diet, the profitability of feeding during 2 seasons, and the effect of a diet with coconut oil on the fatty acid profile of milkfish (Chanos chanos ) ... -
Growth response and carcass composition of red tilapia fry fed diets with varying protein levels and protein to energy ratios
(Asian Fisheries Society, 1991)An 8-week feeding experiment was conducted with red tilapia (Oreochromis ) fry of 0.160 plus or minus 0.035 g initial weight. Twelve diets of 4 protein levels (25, 30, 35 and 40%) and 3 protein to energy (P/E) ratios (111, ... -
Survival of yolk-sac larvae of grouper (Epinephelus suillus) under simulated transport conditions.
(European Aquaculture Society. EAS Special Publication No. 15, 1991)Transport of live fish is a routine activity in aquaculture. Various transport techniques have been reported by Berka. Transport of grouper eggs (Epinephelus suillus) between fisheries stations in Thailand is being conducted. ... -
Mariculture techniques for Epinephelus sp. in the Philippines
(Philippine Council for Aquatic and Marine Research and Development; French Embassy in the Philippines, 1991)This paper reviews the status of different techniques that are presently practiced for Ephinephelus sp. culture in the Philippines. Constraints and problems encountered as well as possible solutions are also discussed. -
Microbound larval feed as supplement to live food for milkfish (Chanos chanos Forsskal) larvae
(European Aquaculture Society, 1991)Highly variable results using Brachionus as food for milkfish (Chanos chanos) larvae may be related to: (1) relatively low content of highly unsaturated fatty acids (HUFAs) in Brachionus and (2) inability of first feeding ... -
An artificial diet for larval rabbitfish Siganus guttatus Bloch.
(Asian Fisheries Society. AFS Spec. Publ. 5, 1991)A 21-day feeding trial was conducted to determine growth, survival and metamorphosis of larval rabbitfish (Siganus guttatus ) fed artificial diets containing approximately 40, 45, 50 and 55% crude protein. Artemia nauplii ... -
