The muskrats, beavers, or parts thereof taken under the authority of such permit shall not be sold or used unless the permitholder also possesses a fur-harvesting permit that is current or valid at the time of the sale or use. The commission may adopt and promulgate rules and regulations in connection with the issuance of such permits. Any person violating this section shall be guilty of a Class III misdemeanor and shall be fined at least fifty dollars.
