Trappers occasionally trap nontargeted species. Because it is unlawful to possess animals out of season or those which are protected species, the following procedure allows trappers to help the DNR collect and utilize the biological data available through carcass examination and ensure that pelts are put to good use.

Trappers must:

• Immediately release live protected animals from the trap. Help may be available to advise on the release of endangered species.
   
• If the animal is dead or dies in the attempt to release it, attach a Michigan incidental seal to the animal before removing it from the trap. Then transport the carcass in an open manner to the nearest DNR office. See Furbearer Registration . The carcass must be surrendered. Michigan incidental seals are available from DNR offices. All incidental seals remain the property of the DNR and must be returned by May 1 each year.
