What must be done to cusk lines set through the ice at night?

Cusk lines set through the ice at night must be checked at least once every hour to ensure safety and compliance with regulations regarding fishing practices. This frequency helps prevent overfishing and ensures that any potential issues, such as entangled fish or changing ice conditions, can be addressed promptly.

Monitoring cusk lines includes making sure that fish are not left unattended for too long, which can lead to stress or death of the fish, as well as ensuring that the lines themselves remain in good condition. While continuous monitoring would provide the best oversight, hourly checks strike a practical balance between diligence and feasibility for night fishing.

Other options suggest either less frequent checks or continuous monitoring, which may not be necessary or practical for maintaining cusk lines effectively. Leaving the lines unattended until morning is unsafe and does not conform to best practice for ethical and responsible fishing.
