Land use and cover changes in the Likangala catchment of the Lake Chilwa basin, Malawi: implications for managing a tropical wetland
Type: Journal Article
This 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 ...
Weed control by adult and juvenile tilapia Tilapia rendalli in rainfed ponds
Type: Journal Article
Two studies were conducted in consecutive years over the time period 14 January to 1 July to determine whether labor-savings and fish growth enhancement could be achieved by stocking Tilapia rendalli directly into ponds ...
Can water productivity metrics guide allocation of freshwater to inland fisheries?
Type: Journal Article
Water productivity (WP) metrics have proven useful in comparing production efficiency of various crops. Recently, it has also been proposed to facilitate more equitable allocation of scarce freshwater resources between ...
Stream degradation, fish abundance and the potential viability of ornamental fisheries in south-western Cameroon
Type: Journal Article
Fifteen sites on nine second- and third-order streams in the Mount Cameroon area, with varying degrees of human disturbance, were sampled during wet and dry seasons over 21 months in 2003–2005 to estimate their potential ...
Feasibility of fisheries co-management in Africa
Type: Journal Article
The current, highly centralized approach to fisheries management seems to be incapable of coping with escalating resource depletion and environmental degradation. Co-management has been identified as an alternative. This ...
Functional aquatic ecosystems, inland fisheries and the Millennium Development Goals
Type: Journal Article
Freshwater allocation in an environment of increasing demand and declining quality and availability is a major societal challenge. While biodiversity and the needs of local communities are often in congruence, the over-riding ...
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 ...
Factors influencing fish prices in Southern Malawi
Type: Journal Article
Nine markets in the Southern Region of Malawi were studied. The prices of 79 separate purchases were compared for market type, species, form of preservation, total length, distance of retail market from the capture fishery ...
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 ...
