WebCathode: anode surface area ratios of as large as 30:1 have been quoted in the literature but there is a limit to the practicality of such configurations. Long narrow cathodes such as copper braids give a better surface area: resistance ratio than metal plates or mesh grids. However braids produce more intense cathode fields in the immediate ... Web7) If electrofishing deemed successful, then reduce voltage and make another run. Repeat until applied voltage and power are too low to result in successful electrofishing. 8) If unsuccessful, increase applied voltage and repeat observations. 9) Upon finding the threshold settings for successful electrofishing, record all outputs
