Genetic improvement programs for aquaculture species in developing countries: prospects and challenges
(2009)Type: Conference PaperAquaculture 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 ... -
Genetic improvement programs for red tilapia Oreochromis spp in Asia
(2011)Type: Conference PaperRed 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 ... -
