This volume report is the findings of the ICLARM-BMZ/GTZ Africa Aquaculture Project (1986-1994). This project studied the smallholder farming systems and developed integrated aquaculture technologies in collaboration with the Malawian Department of Fisheries, the University of Malwai and the Ministry of Research and Environmental Affairs. The traditional farming methods were found to be increasing unproductive and inadequate. New technologies were developed at Malawi National Aquaculture Center and were demonstrated to extension agents and packaged into booklets for farmers. Besides farmers were approached for feedback. The project found that constraints to adoption were best dealt by letting the farmers to decide on the adoption of technology they like. All these aspects helped to adopt new aquaculture technologies for fishery development.
