What can be a consequence of using inappropriate voltage levels in electrofishing?

Using inappropriate voltage levels in electrofishing can indeed lead to fish mortality or stress. When voltage levels are set too high, they can cause significant harm to fish, including physical trauma and death. High voltage can disrupt the normal functioning of fish's nervous systems and lead to overexertion or even cardiac arrest.

Additionally, even if the voltage is not lethal, it can still cause stress to the fish, which may affect their health and behavior in the long term. Stress can lead to changes in feeding patterns, increased susceptibility to disease, and impaired reproductive success. Therefore, managing voltage levels carefully is essential for the welfare of the fish population and the overall ecological balance in the area where electrofishing is conducted.
