Opencast mining is a common practice, after the termination of the mining activities, a mine pit is developed filled up with water. The Physico-chemical parameters of mine water have been analysed in view for the development of fish culture. The necessary measures were taken to make the water conducive for fish culture. The Physicochemical parameters were studied on monthly intervals and sample netting was done to assess the average growth of the fish. It was found that cattle manure's application improved the production of fish food, and the fish grows up to 1.5kg in eighteen months. The growth of Rohu and Mrigal was not satisfactory may be due to the desired food. The use of a submersible pump aerator has increased the dissolved oxygen concentration in different depths of the void. The coal void may be developed for fish culture by simple modification i.e., flooding with surface water, which will improve the water quality, submersible pump aerator, and application of organic and inorganic manures as per need.
