An electrofishing boat uses a generator to produce electricity. The electricity travels to the poles, called booms, at the front of the boat and into the water. The electric field does not kill fish but temporarily stuns or impairs those that swim within a 6- to 8-foot radius from the booms. The fish can then be scooped up and handled with ...
Electrofishing takes place in freshwater and tidal freshwater rivers and streams. Because of the high conductivity of saltwater, it is not conducive to electrofishing. Can anglers use electrofishing equipment to catch fish? No, it is unlawful for …

In addition, electrofishing, which involves fishing with prior stunning of fish by passing electricity through water, is a new phenomenon that has also resulted in reported fatalities (Bohlin et ...
Electrofishing is a common non-lethal fish sampling technique for research and management in freshwaters. Despite steady progress in areas of equipment development and fish welfare, many basic questions remain unanswered. For example, what factors affect differences among species and sizes of fish in their electrical thresholds for capture?

There are some low conductivity situations where electrofishing is going to be incredibly inefficient and frustrating. Distilled water has a conductivity range of 0.5 to 5.0 µS/cm. If typical electrofishing voltages (100 to 1,200V) are applied to water of this low of conductivity, very little current will flow.
Electrofishing acts as a deterrent by identifying these invaders but also helps monitor the expansion and contraction of their range in portions of the stream. Although electrofishing has been used to evaluate stream health for decades, there's recently been a what-if-in-the-world wonderment about another technique, and that technique is ...
