This is the third study that evaluates inland fish farming potential at a continental-level. The study is a follow-up of an earlier assessment of warm-water fish farming potential in Africa by Kapetsky (1994). The overall purpose is to stimulate aquaculture development.
Work began in early January 1997 and the final document was completed just over a year later, by mid March 1998.
Compared with the earlier study, made for Africa, this study is considerably more refined and sophisticated. The most significant refinement was that the new data allowed a sevenfold increase in resolution over that used in the previous Africa study. Sophistication was added by incorporating, for the first time for Africa, a growth model into the GIS to make estimates of yield potential as the number of crops per year possible for three species over the entire African continent.
The present document was made possible through a coincidence of interests. FAO needed to bring up-to-date, the earlier Africa study, to benefit from the most recent and more accurate data available and to make better predictions of fish yield estimations. On the part of the Pond Dynamics/Aquaculture Collaborative Research Support Program (PD/A CRSP) it was an opportunity to enhance existing growth models used in an earlier study of fish farming potential in Latin America by Kapetsky and Nath (1997).
