Drift detection system for floating floating and mid floating fish reef

摘要

PROBLEM TO BE SOLVED: To enable the drift to be detected by an electric wave transmitter while solving the problem that the electric wave transmitter 11 requires time and labor for managing the power source and is easily damaged in an midwater fish bank moored in a floating state in the midwater in the sea through a mooring rope to an anchor part 4 sunk on the sea bottom 3. SOLUTION: The electric wave transmitter 11 not carrying out the transmission when the midwater fish bank is moored in the midwater in the sea, and carrying out the transmission of the electric wave transmitter 11 when the fish bank is floated up by the release of the mooring is installed.
