Areas with suitability for small-scale fish farming were derived from the combined suitability of four land-quality factors important for fish farming development and operation; net annual water requirement for shallow ponds, soil and terrain suitability for the construction of fish ponds, potential livestock wastes and agriculture by-products as feed and fertilizer inputs, and potential for farm-gate sales. Predictions of growth were based on water temperature, in turn predicted from air temperature and wind velocity data. Gridded values of mean monthly daily minimum and maximum temperatures were obtained from the Centre for Resource and Environmental Studies (CRES) at the Australian National University. Mean annual wind velocity was obtained from UNEP/DEIA/GRID-Geneva. The main objective was to map and estimate the areal expanses having suitable to optimum potential for subsistence and commercial warm water fish farming in ponds. A secondary objective was to encourage countries with relatively large potentials for warm water fish farming development to undertake more detailed, national-level studies as a step towards formulating or refining an aquaculture policy and to improve planning for aquaculture development. s_smallc_s.gif thumbnail gif s_smallc.gif large_thumbnail gif Africa Fishery Fish farming Small-scale farming Yield Aquaculture CIFA Technical Paper 32 Africa eng farming 1997-01-01 1998-01-01 -17.3 51.1 -34.6 38.2 This map derives from a wider study that evaluates inland fish farming potential at a continental-level, published by J.Aguilar-Manjarrez and S. S. Nath with the title "A strategic reassessment of fish farming potential in Africa" . CIFA Technical Paper. No. 32. Rome, FAO. 1998. 170p. This study is a follow-up of an earlier assessment of warm-water fish farming potential in Africa by Kapetsky (1994) with the objective to assess locations and areal expanses that have potential for warm-water and temperate-water fish farming in continental Africa.
