Genetic quality of cultured tilapia stocks in Africa
Type: Journal Article
African aquaculture is poised for rapid expansion. However, one of the key constraints holding back growth of the sector is the poor quality of the fish stocks available for culture. The problems of declines in growth ...
Response of two generations of selection to increased body weight in channel catfish, Ictalurus punctatus, compared to hybridization with blue catfish, I. furcatus, Males
Type: Journal Article
Two generations of selection for increased body weight in Kansas (AU-KS-2) and Marion (AU-MS-2) lines of channel catfish, Ictalurus punctatus, resulted in a 12% and 11% increase in body weight at market size, respectively. ...
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 ...
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 ...
Production priorities overshadow genetic quality at African fish hatcheries
Type: Journal Article
Based largely on FAO programs that address rural poverty, small-scale hatcheries have been developed in Africa to produce catfish and tilapia fingerlings. Production practices that fail to maintain genetic diversity, ...
Exploitation and conservation of fish genetic resources in Africa: issues and priorities for aquaculture development and research
Type: Journal Article
Africa harbours a rich biological diversity of native fish resources. Recognition of the potential to use these resources to make significant contributions towards improving African food security through aquaculture has ...
Use and exchange of aquatic genetic resources for food and aquaculture: clarias catfish
Type: Journal Article
There are 58 species of Clarias recognized in FishBase (as of January 2009), 33 in Africa and 25 in Asia. Aquaculture of clariids is important with 30 countries reporting a total production of over 300 000 t worth nearly ...
