Suitability for small scale fish farming (Latin America) - FAO/COPESCAL

Spatial distribution of net annual water loss from ponds through evaporation and seepage. The water balance for fishponds was calculated by estimating the deficit between precipitation and combined evaporation plus seepage. Evaporation was calculated using the Hargreaves formula (i.e. mean monthly minimum and maximum air temperature data were provided by FAO) and seepage was a constant. **Data publication:** 1997-01-01 **Supplemental Information:** This map derives from a wider study that evaluates inland fish farming potential at a continental-level, published by J.M. Kapetsky and S. S. Nath with the title "A strategic assessment of the potential for freshwater fish farming in Latin America " . COPESCAL Technical Paper. No. 10. Rome, FAO. 1997. 128p.

Map derived from the combined suitability of areas apt for small-scale fish farming development and operation with areas with potential yield (crops/y) of African catfish for small-scale farming. 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. **Data publication:** 1998-01-01 **Supplemental Information:** This map derives from a wider study that evaluates inland fish farming potential at a continental-level, published by J.Aguilar-Manjarrez and S.

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.

Map derived from the combined suitability of areas apt for commercial fish farming development and operation with areas with potential yield (crops/y) of African catfish for commercial farming. Areas with suitability for commercial fish farming were derived from the combined suitability of five 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, potential for farm-gate sales and potential market demand. Predictions of growth were based on water temperature, in turn predicted from air temperature and wind velocity data.

Areas with market potential for commercial fish farming in Latin America. Map based on urban locations and motorable roads. It identifies the extent and the location of areas influenced by a certain marketing centre taking into account the travel time and the importance of the urban market (in terms of number of people living in the urban area). Locations or urban centres were provided by ArcWorld at a 1:3 million scale. The road network was derived from the Digital Chart of the World (DCW). **Data publication:** 1997-01-01 **Supplemental Information:** This map derives from a wider study that evaluates inland fish farming potential at a continental-level, published by J.M.
