The Study of Hydrobiology and Aqua Culture Production of Fishes of Mathadivagu Dam District Adilabad Telangana State

Abstract

The productivity condition of Mathadivagu Dam was determined in the current investigation, which took place from June 2017 to 2020. The lake was found to be polluted after 36 months of monitoring due to domestic animal activity and agricultural runoffs. Physicochemical characteristics, biological variables, soil analysis, and fisheries management were all investigated in this study. newlineThe productivity condition of Mathadivagu Dam was determined in the current investigation, which took place from June 2017 to 2020. The lake was found to be polluted after 36 months of monitoring due to domestic animal activity and agricultural runoffs. Physicochemical characteristics, biological variables, soil analysis, and fisheries management were all investigated in this study. The following is a summary of the significant findings. Dam water is not fit for drinking or use in the home since some of the water parameters were discovered to be in extremely high ranges when compared to WHO criteria. Water temperatures ranged from 18 to 390 degrees Celsius. It had a strong negative correlation with dissolved oxygen. The pH of dam water is slightly alkaline, with a narrow range. The turbidity of the water was found to be within acceptable limits. However, during the monsoon season, turbidity levels were higher. The concentrations of dissolved oxygen measured ranged from 4 to 11.4 mg/l. During the monsoon and winter seasons, dissolved oxygen levels were higher, while during the summer, they were lower. CO2 levels were low or non-existent in the dam because CO2 was used by phytoplankton for newlineAbstract newlineii newlinephotosynthesis. Alkalinity was higher in the range, indicating that the carbonates in the water were used due to free CO2. The dam water contains more chlorides, which gives the water a bitter flavor. The nitrogen content of dam water was below acceptable limits, indicating that the dams were not eutrophic. Increased nitrogen levels can cause problems in any water body by changing the color and odor of the water. newlineChlorophyceae populations
