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 ...
Investment Appraisal of Genetic Improvement Programs in Nile tilapia (Oreochromis Niloticus)
Type: Journal Article
The economic benefit derived from a genetic improvement program with Nile tilapia (Oreochromis niloticus) was examined from a national perspective. An industry structure was assumed whereby the genetic improvement program ...
Population structure and genetic variability of six bar wrasse (Thallasoma hardwick) in Northern South China revealed by mitochondrial control region sequences
Type: Journal Article
The genetic relationships among northern South China Sea populations of the six bar wrasse (<i>Thallasoma hardwicki</i>) were investigated. Fish collected from the Solomon Islands were used for geographic comparison. In ...
The impact of genetically improved farmed Nile tilapia in Asia
Type: Journal Article
The International Center for Living Aquatic Resources Management (ICLARM) and its research partners have recently developed a genetically improved Nile tilapia strain. This paper analyzes the potential impact of culturing ...
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 ...
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 ...
Genetic enhancement and conservation of aquatic biodiversity in Africa
Type: Journal Article
There is a pressing need to enhance fish production in Africa through improved farm management and the use of improved fish breeds and/or alien species in aquaculture while at the same time conserve the aquatic genetic ...
Performance and nature of genetically improved farmed tilapia: a bioeconomic analysis
Type: Journal Article
The International Center for Living Aquatic Resources Management (ICLARM), in collaboration with its partner organizations, has developed an improved strain of Nile tilapia (known as the GIFT strain) which shows superior ...
