Regarding fishing lines, what supervision is required in Maine?

In Maine, the regulation regarding fishing lines emphasizes that all lines must be under the immediate supervision of the person who set them. This requirement is in place to ensure responsible fishing practices and to protect the fish population as well as the environment. Immediate supervision helps prevent overfishing and minimizes the chances of fish being caught unnecessarily or outside of legal regulations.

Additionally, it ensures that any fish caught are handled properly and that the lines are not left unattended for prolonged periods, which could lead to complications such as entanglement of non-target species or loss of gear. This regulation reflects a broader commitment to sustainable fishing practices and responsible stewardship of natural resources, making option B the most appropriate answer.
