Farm-economics of genetically improved carp strains in major Asian countries and carp seed price policy model
Type: Journal Article
The study has conducted the micro level analysis of hatchery operators, fishseed-rearing farmers and carp farmers with respect to their socio-economic characteristics, infrastructural development, husbandry practices and ...
Genetic improvement of carp reduces poverty, hunger in Asia
Type: Journal Article
Breeding programs for carp species carried out in a number of Asian countries have delivered genetically fast growing strains to farmers and producers. The economic benefits resulting from the programs are substantial. The ...
Estimation of genetic change in the GIFT strain of Nile tilapia (Oreochromis niloticus) by comparing contemporary progeny produced by males born in 1991 or in 2003
Type: Journal Article
Genetic change in the Genetically Improved Farmed Tilapia (GIFT) Nile tilapia (Oreochromis niloticus) was estimated by comparing the performance of the progeny produced from cryopreserved spermatozoa from the base population ...
Accounting for genotype by environment interaction in economic appraisal of genetic improvement programs in common carp Cyprinus carpio
Type: Journal Article
In this study we examine effects of genotype by environment (G×E) interaction due to re-ranking and scaling effects on economic benefit (EB) and benefit to cost ratio (BCR) from a genetic improvement program in common carp ...
Genetic improvement of Nile tilapia (Oreochromis Niloticus): present and future
Type: Conference Paper
We mainly (but not exclusively) draw upon research and development work carried out by The WorldFish Center (WorldFish). We review the current state of development of selection programs that have had a main focus on growth ...
Transgenic fish: risks and benefits
Type: Journal Article
Advocates of transgenesis consider it an effective means of improving the productivity of aquatic animals. Opponents see it as a threat to both the environment and human health. This is a challenging area because important ...
Aquaculture development 3. Genetic resource management
Type: Report
These Technical Guidelines have been developed to support sections of the FAO’s Code of Conduct for Responsible Fisheries on aspects of genetic resource management in aquaculture. Guidance is provided on broodstock management ...
Adoption and farm-level impact of genetically improved farmed tilapia (GIFT) in the Philippines
Type: Conference Paper
Over the last four decades, the aquaculture sector especially in developing countries has experienced dramatic growth. The increase in aquaculture production is a combination of area expansion and technological change ...
