| This study explores the use of an electric field to aggregate freshwater fish, focusing on the species Rohu. Experiments were conducted on fish to see how different voltage levels (100V, 150V, and 200V) affect fish length, weight, stunning time, and recovery time. At 100V, Rohu had an average length of 9.26 cm, a weight of 7.81 g, took 11.97 seconds to be stunned, and 15.26 seconds to recover. When the voltage was increased to 200V, the time taken to stun the fish decreased significantly to 3.87 seconds, with only a small increase in recovery time to 16.22 seconds. These results suggest that using higher voltages can make stunning more efficient while having a minimal effect on recovery time, showing the potential of electric fields for aggregating fish in freshwater.
