Concepts, alternatives, and environmental considerations in the development and use of improved strains of tilapia in African aquaculture
Type: Journal Article
The status of African populations of farmed tilapia is reviewed and discussed in light of the need for improved strains for commercial aquaculture. Many tilapia populations currently held on African fish farms have been ...
Variable number of tandem repeats in the mitochondrial DNA of Dascyllus trimaculatus
Type: Journal Article
The primary structure of the Dascyllus trimaculatus mitochondrial (mt) control region was determined, and conserved features were identified based on sequence comparisons to other teleostean fish species. Three ...
Aquaculture and the poor: Is the culture of high-value fish a viable livelihood option for the poor?
Type: Journal Article
This study evaluates the role of high-value fish culture in the livelihoods of coastal households in southern Thailand. The study shows that grouper culture, promoted as an alternative to destructive fishing practices, can ...
Genetic characterization of the Aphyosemion calliurum species group and description of a new species from this assemblage: A. campomaanense (Cyprinodontiformes: Aplocheiloidei: Nothobranchiidae) from Southern Cameroon
Type: Journal Article
The Aphyosemion calliurum species group is poorly diagnosed by chromatic and meristic characteristics leading various authors to propose different species as members. We used partial sequence of the mitochondrial cytochrome ...
Perspectives from Agriculture: Advances in livestock breeding-Implications for aquaculture genetics
Type: Journal Article
In this paper we present livestock breeding developments that could be taken into consideration in the genetic improvement of farmed aquaculture species, especially in freshwater fish. Firstly, the current breeding objective ...
Investing in Africa: the WorldFish Center's African strategy in summary
Type: Journal Article
Across much of Africa, freshwater and coastal fisheries provide an important source of food and livelihood for many millions of people. In addition, the aquaculture potential of the continent has only recently begun to be ...
