Lessons from established breeding programs: terrestrial and aquatic animals
Type: Book Chapter
Some relevant components of selection program theory and implementation are reviewed. This includes pedigree recording, genetic evaluation, balancing genetic gains and genetic diversity and tactical integration of key ...
Breeding program requirements in developing countries may differ depending on circumstances
Type: Book Chapter
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 ...
Current trends in the Asian tilapia industry and the significance of genetically improved tilapia breeds
Type: Book Chapter
Tilapia production is increasing rapidly in Asia, and is one of the most popular aquaculture activities in PR China, Philippines, Indonesia, Taiwan and Thailand. The most popular farmed tilapia species is still the Nile ...
Indigenous species for African aquaculture development
Type: Book Chapter
From the history of introductions and the development of successful aquaculture elsewhere, it appears that the use of exotic species to speed up the rate of aquaculture development in Africa is unlikely to be an efficacious ...
Genetic improvement and dissemination of rohu (labeo rohita, Ham.) in India
Type: Book Chapter
Experts carried out selective breeding of Rohu carp for greater harvest weight and yielded an average of 17% genetic gain per generation in 5 generations of selection.
Mass spawning of Oreochromis niloticus for fry production: threats and opportunities for small-scale aquaculture and selective breeding
Type: Book Chapter
Mass selection based on mass spawning can present a feasible and low-cost selective breeding scheme. In mass spawning, however, mating is not controlled and a small number of breeding individuals may account for a ...
Developments in the breeding of cultured fishes
Type: Book Chapter
The controlled breeding of finfish for culture is reviewed with special refer-ence to recent developments and persistent problems. Freshwater species are at present cultured on a much larger scale than brackishwater and ...
Selecting Nile tilapia (Oreochromis niloticus) for growth in low-input environments
Type: Book Chapter
This chapter presents the results from a selective breeding experiment with Nile tilapia in a low input pond environment. The environment was defined as low input as the pond only received chicken manure for fertilisation. ...
Genetic improvement and effective dissemination: keys to prosperous and sustainable aquaculture industries
Type: Book Chapter
There is an increasing demand for fish in the world due to a growing population, better economic situation in some sectors, and greater awareness of health issues in relation to food. Since capture fisheries have stagnated, ...
