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 ... -
Electrophoretic studies on induced gynogenetic diploids and triploids in tilapia (Oreochromis niloticus and O. aureus)
Romana, Maria Rowena R.
(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 ... -
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 ... -
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 ... -
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 ... -
Current fish disease problems in the Philippines and their economic impact
(1987)An account is given of fish disease problems facing the aquaculture industry in the Philippines. The Laguna de Bay fish kills that occurred in December 1985 and February 1986, involving epizootic ulcerative syndrome of ... -
Releasing hormones as an effective agent in the induction of spawning in captivity of sea bass (Lates calcarifer)
(Australian Centre for International Agricultural Research, 1987)A study was conducted to evaluate the effectiveness of luteinising-hormone releasing hormones in the induction of spawning of Lates calcarifer using different administration techniques: pellet implantation, Chinese analogue ... -
Milkfish culture and artificial propagation
(Marine Science Research Laboratory, Memorial University of Newfoundland, 1987)Milkfish (Chanos chanos Forsskal) is widely distributed in the Indo-Pacific region and one of the most extensively cultured fish in Southeast Asia. In the Philippines, Indonesia and Taiwan, over 400,000 hectares of ... -
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 ... -
Constraints and prospects in aquaculture development.
(Nagoya University Corporation, 1987)The development of aquaculture in developing countries of the Asia-Pacific region is constrained by inadequate seeds, diseases and other causes of mortality, lack of effective natural food and formulated feeds, problems ... -
Nutrient flow and physicochemical profile studies of an integrated poultry-salt-Artemia-milkfish-sea bass-shrimp pond production system
(Wetteren, Belgium: Universal Press, 1987)The physicochemical and biological parameters of an integrated flow-through poultry-salt-Artemia-milkfish-sea bass-shrimp pond production system were monitored for 6 months to determine the pattern of nutrient changes and ... -
Commercial production of Artemia in the Philippines
(Universal Press, 1987)This paper summarizes experiences and findings in the development of a tidal saltpond system, integrated for commercial Artemia production. The basic rules of successful pond production of fish and shrimp, which are the ... -
Tilapia hatchery and nursery systems: Operation and management
(Philippine Council for Agriculture, Forestry and Natural Resources Research and Development; Bureau of Fisheries and Aquatic Resources; Aquaculture Department, Southeast Asian Fisheries Development Center, 1987)The successful and profitable production of Tilapia nilotica in ponds or cages is predominantly influenced by the environment and hereditary traits of the stock. Therefore, stocking of high quality fingerlings is a major ... -
