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 fed at 75% satiation and harvested at 600g. Suitable areas 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 loss from ponds through evaporation and seepage; soil and terrain suitability for ponds; potential for agriculture by-products and fertiliser inputs; potential for farm gate sales; and potential market demand. Yield estimations for Nile tilapia 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 Nile tilapia, 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.
