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 ...
Targeting agricultural research and extension for food security and poverty alleviation: a case study of fish farming in Central Cameroon
Type: Journal Article
Over 5 years of participatory on-farm research, market access, profitability, farming systems productivity and economic sustainability were compared on 100 small-scale farms in Central Cameroon. Integration technology based ...
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 ...
Making experiment station results more useful to African fish farmers
Type: Journal Article
Rather 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 ...
Comparative analysis of the environmental costs of fish farming and crop production in arid areas
Type: Conference Paper
Using published data, 20 crop and 19 fish production systems were compared for efficiency of water and nutrient (nitrogen) use. In agriculture, rain-fed cassava was most efficient, followed by rain-fed beans, pivot-irrigated ...
Improving productivity and environmental performance of aquaculture
Type: Working Paper
Fish--including finfish and shellfish--are an important item in the human food basket, contributing 17 percent of the global animal-based protein supply in 2010. They are an especially valuable food source in developing ...
Impacts of aquaculture development projects in Western Cameroon

To measure the impact of past projects on the sustained adoption and development of aquaculture, and to assess the potential for future growth, a participatory rural appraisal (PRA) based on the Research Tool for Natural ...
Farming fish to save water
Type: Journal Article
Author's comment on the farming of fish as a efficient means in terms of water use.
Protocols for the development of indigenous species: polyculture of indigenous species under Malawian smallholder conditions
Type: Journal Article
Shire 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), ...
