Aquaculture and society in the new millennium
Type: Journal Article
Aquaculture as we know it at the beginning of the 21st century is a consolidation of more or less independent experiences. Carvings indicate that the Egyptians were cultivating fish at least 2,500 years ago. The Chinese ...
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 ...
On-farm and on-station comparison of wild and domesticated Cameroonian populations of Oreochromis niloticus
Type: Journal Article
Wild (Sanaga River) and domesticated populations of Oreochromis niloticus were compared onfarm and on-station in the Central Province of Cameroon to determine the degree to which genetic deterioration of stocks may have ...
Heavy metal and faecal bacterial contamination of urban lakes in Yaounde, Cameroon
Type: Journal Article
The objective of this study was to measure the concentration of indicator bacteria and heavy metals in fish, mud and water of the two largest urban inland valleys in Yaounde.
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 ...
Collective marketing may help small-scale fish farmers in Africa
Type: Journal Article
Studies in Cameroon have found that aquafarmers with closer access to urban markets were able to sell much higher quantities of fish at higher prices. In recent research on collective marketing involving 32 rural fish ...
Seasonality, labor and integration of aquaculture into southern African smallhold farming systems
Type: Journal Article
Fish production on Malawian smallholdings is generally limited by the quantity and quality of inputs to the pond (Brummett and Noble 1995). The timing of labor availability and other farm activities limit the amount farmers ...
Ornamental Fishes: a Sustainable Livelihoods for Rainforest Communities
Type: Journal Article
The ornamental fish sector is an extensive and global component of international trade, fisheries, aquaculture and development. However, the scope of this sector and the impact on human and aquatic communities are often ...
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, ...
