Potential yield (crops/y) of carp fed at 75% satiation and harvested at 600 g

Spatial distribution of potential yield (crops/y) of pacu fed at 75% satiation and harvested at 600g. Yield estimations for pacu were based on water temperature which in turn were predicted from air temperature. Mean maximum and minimum monthly air temperatures grids were provide by FAO's Agrometeorology group. In order to explore a range of commercial aquaculture possibilities by the use of the growth model, simulations were conducted for pacu, assuming two different feeding levels and two harvesting weights (600 and 1,000 g). Feed application rates corresponding to 50% and 75% satiation were assumed to represent commercial aquaculture operations with low and high feeding rates, respectively. **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.

Spatial distribution of potential yield (crops/y) of Nile tilapia with a CFB of 0.075 kg/m3 and harvested at 150g. Yield estimations for carp were based on water temperature which in turn were predicted from air temperature. Mean maximum and minimum monthly air temperatures grids were provide by FAO's Agrometeorology group. In order to explore a range of small-scale aquaculture possibilities by the use of the growth model, simulations were conducted for Nile tilapia, assuming a harvesting weight of 150g. Natural food availability was modelled as a function of fish biomass and approach that requires definition of the critical standing crop (in kg/ha) or critical fish biomass (CFB; in kg/m3). For tilapia, ponds that are not heavily fertilized or fed, a CFB of about 0.075 kg/m3 (equivalent to a fish biomass of 750 kg/ha) was considered reasonable. **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.

Map derived from the combined suitability of areas apt for commercial fish farming development and operation with areas with potential yield (crops/y) of Nile tilapia, African catfish and Common carp for small-scale 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. 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.
