Any species of fish not listed above may not be used as bait (live or dead) for fishing in inland waters.
Baitfish traps to be marked
All baitfish traps and baitfish holding boxes must be marked with the name and address of the person who is taking or holding the baitfish.
Importation of baitfish prohibited
It is unlawful to import any live baitfish or smelts into Maine.
Bait Dealer’s license
It is unlawful for any person to deal in live baitfish or live smelts without first obtaining a valid dealer’s license. For further information, contact IF&W. (Note: A person may take live baitfish for their own use, by the use of hook and line or bait trap only, if that person holds a valid fishing license.)
Permit to take baitfish from closed waters
Any person (except licensed bait dealers who receive a permit upon issuance of a license) who wishes to take live baitfish from inland waters which are not currently open to fishing must first obtain a written permit from regional biologist or game warden. There is no charge for this permit. (Note: No permit is required to take baitfish from inland waters open to fishing.) Issuance of a permit does not allow permittee to trespass on private property.
Checking baitfish traps
All baitfish traps must be checked at least once every 7 calendar days by the person who set them.
Storing live baitfish
Live baitfish may not be stored or held in any waters where the use or possession of live fish as bait is prohibited during the entire ice fishing or the entire open water fishing season. This includes waters restricted to the use of artificial lures only, waters restricted to fly fishing, and where there are other prohibitions on the use of live fish as bait. To obtain a list of Maine waters where baitfish cannot be stored please contact IFW’s Augusta Office, or visit IFW’s website: mefishwildlife.com.
Marking holes
When using drop nets to fish through the ice for baitfish/smelts, all holes made in the ice must be marked either by evergreen boughs placed around the hole, or by suspending at least 1 strand of fluorescent biodegradable tape at least 3 feet above the ice around the entire perimeter of the hole so that the tape is visible from all sides.
