Abstract:
In freshwater RAS fish farming, water conditions are crucial and must be taken into account for sustained output. According to APHA (2017) regular operating procedures, assessments of the water quality parameters at three distinct freshwater RAS fish farms in the Varanasi district were made (2017). Temperature of the water is between 25.6 and 26.0 °C, dissolved oxygen concentration is between 6.22 and 7.8 mg/l, total alkalinity is between 136 and 142 mg/l, and total dissolved solids is between 229.72 and 313.67 mg/l. The Varanasi district's recorded water parameter values fall within the optimum suggested limits, indicating a very high potential for the establishment of sustainable freshwater fish farming in the area.
