Which of the following is an effect of increased water conductivity on electrofishing?

Increased water conductivity has significant implications for electrofishing, particularly regarding the behavior of electric current in water. As conductivity rises, the water becomes a better conductor of electricity, which influences how the electric field behaves.

When conductivity is high, the current tends to flow more readily away from the fish rather than concentrating around them. This occurs because the electric field disperses more efficiently in conductive water, making it harder for the current to effectively penetrate and surround the fish. This can lead to less effective stunning as the electrical energy intended to immobilize the fish does not reach them adequately.

Therefore, the correct understanding of the effects of increased water conductivity on electrofishing reveals that the current can indeed flow away from the fish, affecting how well electrofishing can achieve its intended results in terms of capturing or stunning fish.
