If you are out fishing or boating on the Great Lakes, you may encounter commercial trap nets, gill nets and hook lines in most Michigan waters. All state-licensed or Native American commercial equipment are required to be marked with floats or staff/flag combinations. You should stay at least 250 feet away from buoys, since anchor lines may extend several hundred feet in any direction from the floats or flags and along the length of the gear.
Tampering with commercial fishing gear is illegal. Removal or destruction of marker buoys and flags or other disturbance of gear often results in the waste of a valuable resource, since the nets continue to catch fish. They also can create safety problems for others on the water.
