Tanzania modern freshwater aquaculture started back in 1949 when the rainbow trout (Onchorynchus mykiss) were introduced in the Northern and Southern Highland regions by missionaries. This was followed by experimental culture of Tilapia at Korogwe and Malya in Tanga and Mwanza regions respectively, during which ponds were constructed (Balarin, 1985). In this regard, the government and Non-Government Organizations (NGO´s) assisted the communities through provision of fingerlings, technical and financial assistance.
