Interaction of the midgut gland and the ovary in vitellogenesis and consequences for the breeding success: a comparison of unablated and ablated spawners of Penaeus monodon
(European Aquaculture Society, 1989)
The midgut glands and ovaries of unablated and ablated females of Penaeus monodon were examined before and after spawning by light and electron microscopy to elucidate the role of the midgut gland during vitellogenesis. ...
Effect of feeding regimes on growth and survival of bighead carp (Aristichthys nobilis Richardson) fry
(Asian Fisheries Society, 1989)
Two five-week feeding trials were undertaken to evaluate growth and survival of bighead carp (Aristichthys nobilis ) fry of 1.9-2.4 mg mean weight reared on various feeding regimes. In Treatment 1, the carp fry were fed ...
Culture of grouper, sea bass and red snapper
(University of the Philippines Aquaculture Society, Inc., 2001)
Marine fish production has increased dramatically in the past ten years and majority of the cultured species were produced in Asia in 1992. Increase in production was accompanied with concerns on increasing outbreak of ...
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. ...
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 ) ...
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, ...
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 ...
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, ...
Urease activity in soybean meal: effect on its nutritional quality and on growth and survival of Penaeus monodon juveniles.
(International Foundation for Science, 1998)
Based on the results of a survey conducted on the urease activity (UA) in commercial shrimp feed containing soybean meal (SBM) (0.00-29. 70 ppm UA), a study was carried out to determine the effects of different heat ...
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 ...
