Genetic diversity in wild stocks of the giant freshwater prawn (Macrobrachium rosenbergii): implications for aquaculture and conservation
(2003)Type: Journal ArticleThe giant freshwater prawn (Macrobrachium rosenbergii) is cultured widely around the world but little is known about the levels and patterns of genetic diversity in either wild or cultured stocks. Studies have suggested ... -
Response to three generations of selection for increased body weight in channel catfish, Ictalurus punctatus, grown in earthen ponds
(2003)Type: Journal ArticleSelection response for body weight at marketable size was measured for channel catfish, Ictalurus punctatus, grown in earthen ponds at 7500 fish/ha. Three generations of mass selection for increased body weight in Kansas ... -
Breeding and culture of the sea cucumber Holothuria scabra in Vietnam
(2003)Type: Journal ArticleThe sea cucumber Holothuria scabra (sandfish) has been commercially exploited over a wide tropical and subtropical range for centuries. It can produce a high-value grade of beche-demer if processing is carried out well. ... -
Potential for the development of aquaculture in Africa
(2003)Type: Journal ArticleAquaculture production in Africa has remained low despite the huge potential that exists on the continent. In order for this potential to be realized, it is necessary to refocus the direction of aquaculture development. ... -
Genetic make up of exotic catfish Clarias gariepinus in India
(2003)Type: Journal ArticleTwelve enzymes were assayed in Clarias gariepinus collected from India and Thailand. Genetic variation was observed at eight loci, viz EST-1* and 2*, AAT*, ODH*, MDH* GPI* L, GPI-1*M and HK*. Observed heterozygosities were ... -
Pawpaw seed as fertility control agent on male Nile tilapia
(2003)Type: Journal ArticleTo find out if pawpaw (Carica papaya) seeds can induce sterility in male Nile tilapia (Oreochromis niloticus) and to determine if sterility so induced is reversible or otherwise, mature male tilapia of mean weight 40 g ... -
Genetic improvement of the herbivorous blunt snout bream (Megalobrama amblycephala)
(2003)Type: Journal ArticleSelection experiments with the herbivorous blunt snout bream or Wuchang bream (Megalobrama amblycephala) were started in 1985. Mass selection for size and length/depth ratio resulted in a significant increase in growth and ... -
Catching and rearing postlarval cleaner shrimp for the aquarium trade: results from a WorldFish Center project in Solomon Islands
(2004)Type: Journal ArticleBetween 1999 and 2003, the WorldFish Center in Solomon Islands conducted research into the feasibility of a new fishery based on the capture and culture of postlarval coral reef fish for the live fish trade. The work was ... -
The financial feasibility of small-scale grouper aquaculture in the Philippines
(2004)Type: Journal ArticleThis paper presents the results of an economic analysis of the aquaculture of two species of grouper: E. coioides (orange-spotted grouper, green grouper, red-spotted grouper) and E. malabaricus (malabar grouper, black-spotted ... -
GIFT technology manual: an aid to tilapia selective breeding
(2004)Type: ManualThis manual is intended as an aid in the transfer of the selective breeding technology developed by the WorldFish Center and its partners. It was based upon experience and material accumulated during the ‘Genetic Improvement ... -
On-farm and on-station comparison of wild and domesticated Cameroonian populations of Oreochromis niloticus
(2004)Type: Journal ArticleWild (Sanaga River) and domesticated populations of Oreochromis niloticus were compared onfarm and on-station in the Central Province of Cameroon to determine the degree to which genetic deterioration of stocks may have ... -
Size dependent cannibalism in juvenile Nile tilapia (Oreochromis niloticus)
(2004)Type: Conference ProceedingsCannibalism among tilapia fry and fingerlings has been identified as one of the major problems by small-scale hatchery operators (Pantastico et at., 1988). Despite the increasing interest in this species, cannibalism among ... -

Dietary Phytase: an ideal approach for a cost effective and low-polluting aquafeed
(2004)Type: Journal ArticleGlobal fishmeal production from wild-catch sources cannot continue to increase indefinitely; suitable alternatives have to be found for sustainable aquaculture. Plant-based aquafeed seems to be the ideal alternative to ... -
Preservation of genetic diversity in restocking of the sea cucumber Holothuria scabra investigated by allozyme electrophoresis
(2004)Type: Journal ArticlePopulation genetics analyses should be considered when releasing hatchery-produced juveniles of the sea cucumber Holothuria scabra when spawners from nonlocal populations are used. In New Caledonia, within-region genetic ... -
