What is the purpose of using a voltage meter during electrofishing?

Using a voltage meter during electrofishing is crucial for ensuring both the safety and effectiveness of the fish capture process. The primary role of the voltage meter is to monitor and adjust the voltage output of the electrofishing equipment. This is essential because the appropriate voltage level is needed to effectively stun the fish without causing significant harm.

Maintaining the right voltage ensures that the process is efficient, allowing for a proper catch of target species while minimizing the stress and potential injury to the fish. If the voltage is too low, fish may not be effectively stunned; if it is too high, it can lead to injury or death, which goes against ethical practices in fisheries management. Thus, the voltage meter is an important tool for managing these factors properly in the field.
