Comprehensive Assessment of Water Quality Parameters at Jirimukh: Evaluating Its Sustainability for Pisciculture

Abstract

The present study investigates the suitability of Jirimukh as an optimal site for sustainable and advanced fish culture. The research specifically focuses on the water quality parameters at Jirimukh, located at the confluence of the Jiri and Barak Rivers in Manipur. The key physicochemical parameters assessed to determine the optimal conditions for fish growth and survival include chloride ion concentration (Cl⁻), total dissolved solids (TDS), total alkalinity (TA), pH, turbidity, total hardness (TH), dissolved oxygen (DO), biochemical oxygen demand (BOD), temperature (Temp), and flow rate. The results indicate a sub-alkaline pH range (6.9–7.5) throughout the year, with dissolved oxygen (DO) levels being highest during the winter months, exhibiting minimal seasonal variations. All recorded values fall within the ideal ranges for aquaculture, supporting the survival of oxygen-demanding fish species. However, increased BOD levels during the monsoon season, primarily due to runoff from agricultural and livestock activities, pose a challenge by promoting eutrophication. Additionally, seasonal fluctuations significantly impact stream flow rates and other water quality parameters. The findings underscore the importance of maintaining water quality within the optimal ranges for sustainable fish farming. The study highlights the need for an integrated aquaculture management approach, alongside continuous monitoring of water quality, to ensure the sustainability of fish culture in Jirimukh, Jiribam.
