An individual shall not have in his or her possession any net, set lines, jack or other artificial light of any kind, dynamite, giant powder, or other explosive substance or combination of substances, hook and line, or any other contrivance or device to be used for the purpose of taking fish in violation of this part or any other act or part. Any such property, contrivance, or device found in the possession of an individual or found in a boat, boathouse, or any other place on any of the waters of this state or along the shores of the waters of this state must be confiscated and disposed of in the manner provided by law. An individual shall not have a gaff in his or her possession on or along any trout stream in this state or use, except from June 1 to Labor Day, on any trout stream a single hook of any kind that is more than 3/8 inches between the point of the hook and the shank. This section does not prohibit the use or possession of minnow seines, minnow traps, or dip nets as provided in section 48730 or the use and possession of seines, nets, spears, or artificial lights for the use of which a lawful permit or license has been issued by the department. Commercial anglers who have licenses to take fish in the Great Lakes may have in their possession nets or hook lines for that purpose only. In prosecutions for the violations of this section, and in proceedings for the confiscation of the property described in this section, the possession of any such property, contrivance, or device or, when not found in possession of any individual, the presence of any such property in a boat, boathouse, or any other place on the waters of this state or along the shores of the waters of this state is prima facie evidence that the property is owned, possessed, or used for the purpose of violating this part. The possession of any such property, contrivance, or device on the waters of this state that are closed to all fishing during the closed season on or along those waters is prima facie evidence that the property is owned, possessed, or used for the purpose of violating this part. This act or any other act does not apply to the department in its program in fisheries management or in the control of aquatic vegetation by individuals under permit issued by the department when, in the opinion of the department, that control is not inimical to the public interest.
