Heterosis, direct and maternal genetic effects on body traits in a complete diallel cross involving four strains of red tilapia Oreochromis spp
Type: Conference Paper
Heterosis, direct additive genetic and general reciprocal effects were estimated from a complete diallel cross involving four strains of red tilapia Oreochromis spp from Malaysia, Stirling, Taiwan and Thailand. The mating ...
Potential applications of reproductive and molecular genetic technologies in the selective breeding of aquaculture species
Type: Conference Paper
The use of reproductive and genetic technologies can increase the efficiency of selective breeding programs for aquaculture species. Four technologies are considered, namely: marker-assisted selection, DNA fingerprinting, ...
Genetic improvement programs for aquaculture species in developing countries: prospects and challenges
Type: Conference Paper
Aquaculture in developing countries is largely based on unimproved fish strains. There is ample evidence indicating the potential of genetic improvement programs and a range of selection methods may be used. Examples of ...
Importance and implementation of simple and advance selective breeding programs for aquaculture species in developing countries
Type: Conference Paper
Aquaculture is predicted to play a major and ever increasing role in meeting human needs for protein. In terrestrial animal and plant species genetic improvement programs have made a substantial contribution to productivity ...
Genetic improvement programs for red tilapia Oreochromis spp in Asia
Type: Conference Paper
Red tilapia (Oreochromis spp) has become popular in Asian countries due to its greater economic value relative to Nile tilapia. As there is a growing demand for quality seed of this species, the WorldFish Center has initiated ...
Genetic analysis of the GIFT strain (Nile Tilapia, Oreochromis niloticus) in Malaysia
Type: Conference Paper
The Genetically Improved Farmed Tilapia (GIFT) strain is well known worldwide because of its high performance. A first phase of the project ended in 1997 after five generations of selection. In 2002, the GIFT population ...
Establishment of a satellite nucleus of the GIFT strain at Rajiv Gandhi Center for Aquaculture (RGCA) to support tilapia production in India
Type: Conference Paper
Rajiv Gandhi Center for Aquaculture (RGCA), India was interested in obtaining the Genetically Improved Farmed Tilapia (GIFT strain) for aquaculture in the country. Discussions were made and joint proposal was developed ...
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 ...
Estimation of genetic change in the GIFT strain by comparing contemporary progeny produced by males born in 1991 or 2003
Type: Conference Paper
During the development of the GIFT (Genetically Improved Farmed Tilapia) strain in Philippines sperm was frozen from a sample of males from founder stocks and subsequent generations. In this paper a comparison of progeny ...
Mass selection for increased body weight at harvest over five generations in silver barb, Puntius gonionotus
Type: Conference Paper
Silver barb (Puntius gonionotus Bleeker 1850) is an Asian carp that is popular as a food fish. It is distributed throughout Thailand in rivers, canals, reservoirs and swamps. It is also cultured in ponds and paddy fields. ...
