Hundreds of thousands of seasonal ponds and ditches in rural Bangladesh are mostly derelict or underutilized, due to lack of appropriate aquaculture technologies. On-station and on-farm research undertaken by the Fisheries Research Institute resulted in development of management practices ior culture of silver barb (Puntius gonionotus) which can be grown to market size in short periods in such waters. These research results were disseminated to a large number of farmers throughout the country by various extension agencies during 1991. Two hundred fifty-three farmers in different parts of the country, to whom the technology was extended by a nongovernmental organization, the Bangladesh Rural Advancement Committee (BRAC), were surveyed before and after adoption of the technology, to evaluate the socioeconomic viability and farmers' assessment of the technology in different agro-climatic zones.
