An investigation about the physico-chemical and biological parameters, management practices and production potential of kua fisheries of Raktodaha beel, Bogra, Bangladesh was carried out in three stations viz., station A (shallow), station B (medium deep) and station C (deepest). The physico-chemical parameters of the kuas, such as water depth, water temperature, turbidity, dissolved oxygen, pH and total alkalinity were found to range between 0.38-1.44 m, 20.1-28.7<sup> 0</sup>C, 52.1-86.0 ppm, 3.7-5.2 ppm, 5.5-6.4 and 55.7-97.0 ppm respectively among three stations. The abundance of phytoplankton and zooplankton varied between 28,000-58,000/l and 210-325/l respectively. The average fish production in the kuas of three stations was found to range from 300.6-459.6 kg/ha with the highest production in deeper region and the lowest production in shallow region. Out of 24 species recorded in the kuas, Mastacembelus spp. and Heteropneustes fossilis showed higher contribution to the total production.
