Genetic quality of cultured tilapia stocks in Africa
(2008)Type: Journal ArticleAfrican 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 ... -
Heavy metal and faecal bacterial contamination of urban lakes in Yaounde, Cameroon
(2003)Type: Journal ArticleThe 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. -
How can research best serve the needs of aquaculture in subsaharan Africa?
(1994)Type: Journal ArticleDiscussion on whether research is the answer to best serve the needs of aquaculture in SubSaharan Africa is presented. New methods of user-participatory, on-farm research being tested by ICLARM and other agencies in Asia ... -
Indigenous species for African aquaculture development
(2007)Type: Book ChapterFrom 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 ... -
Inland fisheries and aquaculture
(2007)Type: Book ChapterThis review showed that the contributions from inland fisheries and aquaculture in economic and social development are undervalued and warrant integrated water management approach to address the various challenges presented ... -
Integrated resources management, integrated agriculture-aquaculture and the African farmer
(1995)Type: Journal ArticleDespite the expenditure of huge amounts of money and human effort, the Green Revolution has largely failed to benefit the vast majority of the rural poor in Africa: those smallholding farmers who sell little, if any, of ... -
Intensity and profitability of Clarias nursing systems in periurban Yaoundé, Cameroon
(2006)Type: Journal ArticleTo target development efforts, the technological options for investments in Clarias gariepinus hatchery systems were compared for cost, average weight, number of fingerlings harvested, survival and profitability in periurban ... -
Land use and cover changes in the Likangala catchment of the Lake Chilwa basin, Malawi: implications for managing a tropical wetland
(2003)Type: Journal ArticleThis study analyses land use and cover changes in the Likangala River catchment of Lake Chilwa, Malawi, an endorheic tropical African lake. It also examines how land use-related physico-chemical and hydrological parameters ... -
Making experiment station results more useful to African fish farmers
(1998)Type: Journal ArticleRather than using more or less ideal conditions for setting experimental controls, the use of conditions similar to those likely to be encountered by farmers should produce research results which are realistically achievable ... -
On-farm and on-station comparison of wild and domesticated Cameroonian populations of Oreochromis niloticus
(2004)Type: Journal ArticleWild (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 ... -
Participatory research boosts catfish egg, fry production in Cameroon
(2007)Type: Journal ArticleThe omnivorous African sharptooth catfish is a valuable species suitable for culture by smallholder farmers in Cameroon. A five-year research project that brought farmers together with research interests established simple, ... -
Production parameters and economics of small-scale tilapia cage aquaculture in the Volta Lake, Ghana
(2010)Type: Journal ArticleTo calculate the potential for cage aquaculture to create economic opportunities for small-scale investors on the Volta Lake, Ghana, a local NGO with technical support from the Government of Ghana ran two trials (one of ... -
Production priorities overshadow genetic quality at African fish hatcheries
(2004)Type: Journal ArticleBased 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, ... -
Protocols for the development of indigenous species: polyculture of indigenous species under Malawian smallholder conditions
(1996)Type: Journal ArticleShire tilapia, Oreochromis shiranus shiranus (Boulenger 1897), was grown in monoculture and polyculture with either straightfin barb, Barbus paludinosus (Peters 1852), or threespot barb, Barhus trimaculatus (Peters 1852), ... -

Relative Importance of Various Predators in Clarias gariepinus Fry Mortality in Cameroon
(2006)Type: Journal ArticleTo estimate the relative importance of the most common predators of Clarias gariepinus fry, increasing levels of protection were afforded to exclude amphibians, aquatic arthropods and birds. At a stocking density of 10 ... -
Response of two generations of selection to increased body weight in channel catfish, Ictalurus punctatus, compared to hybridization with blue catfish, I. furcatus, Males
(1999)Type: Journal ArticleTwo 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. ... -
Rivers of the Lower Guinean rainforest: biogeography and sustainable exploitation
(2003)Type: Book ChapterThe Lower Guinean rainforest of Southern Cameroon, continental Equatorial Guinea, Gabon and the People's Republic of the Congo and its associated biodiversity is being destroyed at a rate of 1 million ha per year by poorly ... -
Role of aquaculture in increasing water productivity
(2006)Type: BookThe objective of this review is to compare aquaculture to other food production strategies in terms of freshwater use, and demonstrate how aquaculture can be made to have positive impacts on food supply, economic growth ... -
Seasonality, labor and integration of aquaculture into southern African smallhold farming systems
