Which technique is NOT recommended to minimize the "fright zone" during electrofishing?

The technique of using the anode to point at habitats is not recommended for minimizing the "fright zone" during electrofishing. The "fright zone" refers to the area surrounding the electrofishing unit where fish may be startled or disturbed by the electric field generated. Employing the anode to focus on specific habitats can inadvertently increase the intensity of the electric field in certain areas, making fish more likely to be frightened and flee from the targeted location.

Minimizing the fright zone involves techniques that promote a less aggressive interaction with fish. Gentle movement, avoiding quick actions, and repositioning the crew before turning on the electrofishing equipment help in creating a more serene environment. These strategies allow fish to adjust gradually rather than being startled by sudden changes or aggressive movements, thereby improving capture efficiency and reducing stress on the fish population being studied.
