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 ... -
Survival of newly-hatched larvae of Epinephelus malabaricus at different salinity levels.
(European Aquaculture Society. EAS Special Publication No. 15, 1991)The development of an appropriate hatchery culture-technique for grouper Epinephelus malabaricus requires knowledge on the biology of this species. The environmental requirements, a critical aspect of biology, have, however, ... -
Defatted soybean meal and Leucaena leaf meal as protein sources in diets for Penaeus monodon juveniles
(Asian Fisheries Society, 1990)Penaeus monodon juveniles, mean weight 0.38 g, were fed 12 practical diets with 30, 20 or 16% Peruvian fish meal, 15 or 35% defatted soybean meal (DSM), 10% Leucaena leucocephala , leaf meal (LM), and 15% shrimp meal with ... -
Growth and survival of Oreochromis niloticus, O. mossambicus and their F1 hybrids at various salinities
(Asian Fisheries Society, 1990)Growth and survival of Oreochromis niloticus, O. mossambicus, and their F1 hybrids were studied at various salinities (0-32 ppt) in net cages inside 12-tonne concrete tanks after acclimation. Growth, measured ... -
Milkfish fry collection and handling
(Food and Agriculture Organization of the United Nations, South Pacific Aquaculture Development Project, 1990)Milkfish fry can be collected in almost all the coastal waters of the tropical Indo-Pacific region. The fry season occurs at different times of the year in various sections of the species' geographical range. The season ... -
Mineral requirements of Penaeids
(Institut Francais de Recherche pour l'Exploitation de la Mer, 1990)Marine shrimps absorb minerals from their aquatic environment aside from the minerals that come from the food they eat. Thus, the dietary requirement of shrimps for certain minerals will depend on the amounts and availability ... -
Bacterial exoskeletal lesions of the tiger prawn Penaeus monodon
(Asian Fisheries Society, 1990)Tank- and pond-reared Penaeus monodon with exoskeletal lesions were examined. The incidence rate was up to 36% for broodstock in concrete tanks and to 20% for pond-reared prawns. The increase in disease incidence was related ... -
Hormone-induced spawning of cultured tropical finfishes
(IFREMER, 1990)Commercially important tropical freshwater and marine finfishes are commonly spawned with pituitary homogenate, human chorionic gonadotropin (HCG) and semi-purified fish gonadotropins. These preparations are often administered ... -
Heterogeneity in Philippine milkfish populations
(Asian Fisheries Society, 1990)Twelve milkfish (Chanos chanos ) populations from 6 coastal areas in the Philippines, collected at the fry stage and reared until fingerling size, were analysed for electrophoretic variation at 28 presumptive loci. Seven ... -
Fisheries biology of milkfish (Chanos chanos Forskal)
(Food and Agriculture Organization of the United Nations, South Pacific Aquaculture Development Project, 1990)Milkfish (Chanos chanos Forskal) is one of the most important food fish species in the world. In Indonesia, Taiwan and the Philippines, more than a quarter of a million tonnes of milkfish are harvested annually in brackish ... -
Survival of larval milkfish, Chanos chanos, during changeover from endogenous to exogenous energy sources
(Asian Fisheries Society, 1990)Survival of laboratory-reared larvae of milkfish, Chanos chanos , during transition from the prelarval to postlarval stages was examined in relation to the changeover of energy sources. The prelarval and early postlarval ... -
Milkfish culture in the Philippines
(South Pacific Aquaculture Development Project, Food and Agriculture Organization of the United Nations, 1990)In the Philippines, the level of intensity of Chanos chanos culture is categorized into traditional and extensive management. Pond types for different culture systems, stocking practices, acclimation practices, water ... -
Optimized feeding strategies in the larviculture of the Asian seabass Lates calcarifer.
(Asian Fisheries Society, 1990)This paper reports on the progress made at the Tigbauan hatchery of SEAFDEC in the Philippines, with the larviculture of the Asian seabass Lates calcarifer when using w3-HUFA enriched Brachionus and Artemia . In view of ... -
Dietary manipulation to control the chronic soft-shell syndrome in tiger prawn, Penaeus monodon Fabricius.
(Asian Fisheries Society, 1990)Penaeus monodon collected from brackishwater ponds in Iloilo, Philippines, were induced to become soft-shelled in the laboratory for 3-4 weeks. Eight isocaloric and isonitrogenous diets containing 0:0; 0:1; 1:0; 1:0.2; ... -
Practical water chemistry for fishfarmers I. Teaching strategies
(Asian Fisheries Society, 1990)Years of ambitious, yet seemingly futile, efforts by the authors in the Philippines in making fishfarmers comprehend and appreciate chemical reactions the way chemists do, paved the way for the formulation of teaching ... -
A statistical procedure for using "reference fish" to compare the growth of genetic strains in aquaculture
(Asian Fisheries Society, 1990)No simple, well-accepted procedures exist for comparing the relative performance of genetic strains of fish in aquaculture environments. The major technical problem is providing adequate statistical replication of ponds ... -
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 ... -

Status of sanitation and marketing of mollusc in the Philippines
(Regional Seafarming Development and Demonstration Project; Network of Aquaculture Centres in Asia, 1989)The mollusc industry of the Philippines has contributed to the economic development of the country in terms of food production and dollar earning. The industry has continuously provided cheap but nutritious shellfishes. ... -
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 ...
