Description :
The important objective of this communication to explain the abundance as well as the status of fish fauna and impact of water pollution on fish production in Bori Dam and Khandala Dam, in Osmanabad District, Maharashtra. For the investigation of this problem the data of total fish production form last 7 years was collected by survey from fishermen societies of dam. For investigation ecological aspects of the dam water samples were collected and evaluate in the research laboratory. After the investigation the results observed that the pH of ranged from 8.3-9.2 and 8.4-9.8, the D.O. was observed 2.2-4.4 mg/lit and 2.3-3.3 mg/lit. The B.O.D. values 2.7-6.4 mg/lit and 2.9-6.3 mg/lit; T.D.S. values are 79-87 mg/lit and 82-92 mg/lit and 103-178 mg/lit the calcium ranges between 126 to 154 mg/lit and 54-127 mg/lit; Magnesium is ranges between 41-47 mg/lit and 31-38 mg/lit ; The chloride content was 34.2-43.1 mg/lit and 35.1-41.4 mg/lit ; The nitrate content was 0.04-0.05 mg/lit and 112 mg/lit; the total alkalinity content was ranges between 48-131 mg/lit and 74-143 mg/lit respectively observed in Bori dam and Khandala dam of Osmanabad district. The result values showed that the domestic activity, industrial effluents or wastes, agriculture waste etc. are the main source of pollutants of water. Other secondary natural causes are biodegrading portion of plants as well as animal waste and siltation by erosion of soil in the study area. Key-words: Ecological aspects – Fish production water quality – pollution.
