Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations Spring Electrofishing TN

IIRC e-shock surveys sample about 10% of the total fish population. Water clarity and temp plays a HUGE role in success rates. Even if it was during the BG spawn, you can turn off the juice and motor around the BG spawning areas. Shocking part of an area would be a good indicator of BG size, and because of their fecundity, I don't think that it would make much of an impact on that years spawn. There would be so many fish stunned that you couldn't scoop them all before you ran out of room in the boat.
