Development of broodstock for small-scale shrimp hatchery (with particular reference to Penaeus monodon)
(South China Sea Fisheries Development and Coordinating Programme, 1982)
To be self-sufficient in spawner/larval supply, a small-scale Penaeus monodon hatchery should have the following: 1) broodstock tanks or pens depending on location and other factors; 2) pond sources of broodstock of ...
Prawn nutrition, feed development and feeding techniques for grow-out and broodstock
(Philippine Council for Aquatic and Marine Research and Development, 1989)
Knowledge on nutritional requirements of prawn juveniles and broodstock are scanty. However, relatively more information is now available with regard to requirements of juveniles compared to that of broodstock.
Many ...
Studies on broodstock of sugpo Penaeus monodon Fabricius and other penaeids at the SEAFDEC Aquaculture Department
(Cochin, India: The Marine Biological Association of India, 1982)
For hatchery production of Penaeus monodon and other penaeid fry, the SEAFDEC Aquaculture Department is dependent mainly on captive broodstock in the form of ablated females, using up to 1,500 spawners in one year. The ...
Nutrition and feeds of Nile tilapia broodstock and fry
(Philippine Council for Aquatic and Marine Research and Development, 1989)
Studies on some aspects of tilapia and feed formulation conducted at BRS are reviewed in this paper.
The effect fo varying dietary crude protien on growth and spawning frequency of tilapia was determined under laboratory ...
A comparison of two prawn (Penaeus monodon ) brood stock systems—land–based tanks and marine pens
(World Aquaculture Society, 1981)
The paper compares two prawn (Penaeus monodon) brood stock systems—land-based tanks and marine offshore pens. Construction costs and annual maintenance and operating costs total US\$1,430 and \$2,550 for the tank and \$1,500 ...
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 ...
Spawner size and the biological components of the reproduction process in Penaeus monodon Fabricius.
(1986)
The biological components of the reproduction process of Penaeus monodon spawners collected from the wild along Tigbauan-Guimbal coastal area, Philippines, were evaluated. Data were collected on wet body weight, eggs per ...
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 ...
Hatchery production of Oreochromis niloticus L. at different sex ratios and stocking densities
(Elsevier, 1988)
The influence of various sex ratios and stocking densities on hatchery production of Nile tilapia, Oreochromis niloticus L., was studied in land-based (concrete tanks) and lake-based (hapa nets) systems. In both hatchery ...
The effect of stress on spawning of brood fish and survival of larvae of the rabbitfish, Siganus guttatus (Bloch)
(Elsevier, 1989)
The effects of stress due to handling, and repeated sham and human chorionic gonadotropin (HCG) injections on spawning and survival of the rabbitfish, Siganus guttatus were studied. Results showed that stress significantly ...
