ENVIRONMENTAL FACTORS AFFECTING FISH SPECIES AND POND WATER IN BANGLADESH (Pages : 22 - 27)
M.G. HOSSAIN, J.M.A. HAQUE AND M. WAHIDUZZAMANStudies were conducted on environmental factors affecting fish species and pond water to know the vital parameters of pond water environment required for agro-technology adoption, and to identify the fish input utilization for improved technologies involving profitable species. The studies were conducted in different Agro-Ecological Zones (AEZ) of Bangladesh river systems. The variables were AEZ sites and response of different categories of farmers, fishers and stake holders. The results obtained showed that the size of ponds were within 30-50 decimal range. The local carps were the main species. Seasonal fishes should also get more priority for development with government support. Rearing of fingerlings is practiced mostly in Atrai Korotoa Zone. Locally mixed farming materials were mostly used in Meghna Zone (Comilla-Brahmanbaria). Meghna river system has more potentials for aquaculture followed by Atrai- Korotoa river system. Atrai-Korotoa Zone retains higher percentage for seasonal and cat fishes, specially Shing (Heteropneustis fossilis), and seasonal species in Barind areas. So the bigger size ponds should be considered as a favourable system considering environmental concerns. It was recommended that the river systems and bigger size ponds have more potentials for fish and fisher developments in Bangladesh. This set of recommendations have been made involving maintenance of water quality, propagation of high value fishes, enforcing legal monitoring and introduction of microfinance based on the present research findings.
