Status of shrimp nutrition and feed development in Southeast Asia.
(Asian Fisheries Society. AFS Spec. Publ. 4, 1989)World demand for shrimp has increased significantly in the last decade. Of the 32 species investigated, the most commonly cultured in Southeast Asia is the Penaeus monodon . Formulated feed constituted around 50% of the ... -
Larval rearing of Penaeus monodon: Feeds and feeding techniques
(Philippine Council for Aquatic and Marine Research and Development, 1989)Larval rearing of P.monodon requires mass culture of selected phytoplankton and zooplankton species. In the protozocal stage, Skelatonoma; Chaetoceros or Tetraselmis is given singly or in combination. The rotifer Brachionus ... -
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 ... -
Amino acid and fatty acid profiles in aquaculture nutrition studies
(Asian Fisheries Society, 1989)The amino acid profile is an important parameter in the evaluation of protein quality and in requirement studies. Amino acid profiles are usually determined in 2 steps: hydrolysis of the protein to constituent amino acids ... -
Milkfish nutrition: A review
(Philippine Council for Aquatic and Marine Research and Development, 1989)This paper reviews recent work on milkfish nutrition. Substantial progress had been made towards understanding the digestive physiology of milkfish. Major enzaymes envolved in the digestions of carbohydrates, protein and ... -
Finfish nutrition in Asia: A review
(Philippine Council for Aquatic and Marine Research and Development, 1989)This review paper highlights counry reports presented at the Workshop on Asian Finfish Nutrition Sponsored by the International Development Research Center of Canada in 1983. Result of researches on the amino acid, lipid, ... -
Electrophoretic studies on induced gynogenetic diploids and triploids in tilapia (Oreochromis niloticus and O. aureus)
(Department of Fisheries; International Center for Living Aquatic Resources Management. ICLARM Conference Proceedings 15, 1988)Preliminary electrophoretic screening of laboratory maintained tilapia stocks revealed enzyme polymorphism at 3 co-dominantly inherited loci--adenosine deaminase (Ada), aminopeptidase (Ap) and malic enzyme (Me-2). Oreochromis ... -
Response of Nile tilapia (Oreochromis niloticus) fry to diets containing Azolla meal
(Department of Fisheries, Bangkok, Thailand; International Center for Living Aquatic Resources Management, 1988)Sun-dried Azolla pinnata was ground and incorporated into experimental diets at various levels (8.50, 17.00, 25.46, 34.00 and 42.45% of the diets) to replace fish meal in a control diet isonitrogenously. All feeds contained ... -
Trace analysis of nitrite ion in seawater using ion chromatography
(Kyoto University, 1988)An ion chromatographic method of separating and detecting nitrite in sea water is described. The system includes precolumn, new hydrophilic separation column, suppressor and two-valve system. Nitrite was diverted, trapped ... -
Cannibalism among different sizes of tilapia (Oreochromis niloticus) fry/fingerlings and the effect of natural food
(Department of Fisheries, Bangkok, Thailand; International Center for Living Aquatic Resources Management, Manila, Philippines, 1988)Experiments were conducted in jars, tanks and aquaria to determine the occurrence of cannibalism among 7 different size groups of Nile tilapia (Oreochromis niloticus ) fry and fingerlings. Cannibalism became more intense ... -
Polyculture of the tiger shrimp (Penaeus monodon) with Nile tilapia (Oreochromis niloticus) in brackishwater fishponds
(1988)A study was conducted in fifteen 500-m2 ponds to determine the growth, survival and production of Penaeus monodon (Fabricius) in polyculture with Oreochromis niloticus (Linnaeus) and the extent of competition ... -
Hematological and histopathological changes in Oreochromis mossambicus after exposure to the molluscicides Aquatic and Brestan
(Department of Fisheries; International Center for Living Aquatic Resources Management, 1988)Duplicate static 96-hour bioassays were conducted to determine the median lethal concentration for Oreochromis mossambicus (LC50) of two organostannous molluscicides, commonly used in fishponds: Aquatin and ... -
Problems of diseases in prawn projects.
(1988)A major factor that influeces the success of production in the prawn industry is the occurrence of disease. Early stage of prawn in hatchery-nursery systems are subject to attacks of viruses, bacteria, fungi and protozoan ... -
Hormonal changes accompanying sexual maturation in milkfish Chanos chanos Forsskal
(Nagoya University Corporation, 1987)In spite of the economic importance of milkfish to the Southeast Asia, relatively little information is available on its reproductive biology and physiology. Milkfish has a prolonged juvenile phase undergoes first sexual ... -
