(5) Gillnet floats or buoys. When a gillnet is deployed in the water, the floats or buoys attached to the gillnet (head rope or float line) must maintain contact with the surface at all times, and the gillnet must not be used within 20 ft (6.1 m) of the bottom and must not be anchored to the bottom.
