Not Too Shocking: Your Electrofishing Questions

Electrofishing is a technique used in fisheries science to sample fish populations. Sampling is when biologists study a number of fish from a certain area, measuring and examining them and recording the statistics. When biologists electrofish, a generator or battery gives off an electrical current that runs through the water.
