With an estimated 90% of baitfish sales occurring during winter, it’s important for anglers to be aware of Maine’s live-bait regulations. Because of the importance of our freshwater ecosystems, we walk a fine line trying to prevent the illegal introduction of harmful fish species while allowing anglers to continue Maine’s cultural tradition of using live baitfish where appropriate. Maine’s native salmonids (landlocked salmon, brook trout, and whitefish) evolved in an environment with very little competition from other fish species for resources. Many Maine anglers have observed the impacts of species like smallmouth bass, largemouth bass, northern pike, and black crappie on native salmonid fisheries firsthand. Moreover, since our river basins drain directly into the Atlantic Ocean, our native fish were likely not exposed to many of the diseases present in the country’s larger drainages (e.g., Mississippi River).
Maine recognized the external threats early on and made it illegal to import live baitfish from other states. In fact, Maine’s ban on baitfish importation was upheld by the United States Supreme Court in 1986 (Maine v. Taylor) which recognized the ecological need to limit introductions of noxious species. Maine has a long history of protecting individual populations with regulations like “Use or possession of live fish as bait is prohibited” or “Artificial lures only”. Recently we went a step further and MDIFW initiated a general law ban on using live fish as bait in Maine’s North Zone, which is the stronghold of brook trout in the eastern United States. However, walking the fine line, the use of live baitfish is still permitted in some waters within the North Zone.
There are 17 species of fish that are legal to use as live bait in Maine shown in the table below. The majority, 11, of these fish are from the minnow family (Cyprinidae) and the remaining species include two suckers (Catostomidae), two killifish (Fundulidae), the American eel (Anguillidae), and rainbow smelt (Osmeridae). Most baitfish are harvested by licensed wholesalers and, as previously stated, these fish must be harvested from Maine waters. Harvested baitfish are sold to anglers by wholesalers and licensed retailers. Recreational anglers are also allowed to harvest their own live baitfish for personal use with standard minnow traps as defined in Maine’s Fishing Laws.
Fish species eligible to use as live baitfish in Maine’s inland waters:
|Common Name||Family||Latin Name|
|American Eel||Anguillidae||Anguilla rostrata|
|Longnose Sucker||Catostomidae||Catostomus catostomus|
|White Sucker||Catostomidae||Catostomus commersonii|
|Blacknose Dace||Cyprinidae||Rhinichthys atratulus|
|Common Shiner||Cyprinidae||Luxilus conutus|
|Creek Chub||Cyprinidae||Semotilus atromaculatus|
|Eastern Silvery Minnow||Cyprinidae||Hybognathus regius|
|Fathead Minnow||Cyprinidae||Pimephales promelas|
|Finescale Dace||Cyprinidae||Chrosomus neogaeus|
|Golden Shiner||Cyprinidae||Notemigonus crysoleucas|
|Lake Chub||Cyprinidae||Couesius plumbeus|
|Northern Redbelly Dace||Cyprinidae||Chrosomus eos|
|Pearl Dace||Cyprinidae||Margariscus margarita|
|Banded Killifish||Fundulidae||Fundulus diaphanus|
|Rainbow Smelt||Osmeridae||Osmerus mordax|
It is illegal to harvest, sell, or use fish species not on the list of eligible species for live bait.
Anglers baiting their hooks are the last line of defense stopping the spread of unwanted species. Therefore, educated anglers can play a large role in preventing the spread of unwanted species:
- One of the easiest things to check is spines. All of the legal baitfish species have soft flexible rays in their fins. If a fish has hard spines in their fins it is not a legal species and cannot be used as bait. Examples of fish with spines include yellow perch, largemouth bass, smallmouth bass, black crappie, and brown bullhead. The spread of species like northern pike and muskellunge (which do not have spines) is also of great concern. While young pike and muskie can be difficult to tell apart from native chain pickerel, none of these closely related fish (in the family Esocidae) are legal to use as bait.

If you are interested in learning more about identifying fish species, detailed identification characteristics for most Maine fish can be found using Wisconsin’s fish identification tool, found here https://www.seagrant.wisc.edu/fish-id/.
Another critical practice to employ that prevents spreading species is to never dump your bait bucket where fish could get into the water. MDIFW suggests that anglers always dispose of unwanted baitfish on land or in the trash.
Lastly, we try to make our fishing regulations as easy to access as possible. Law books are available at many licensing locations throughout the state. We also produce an online regulation mapping tool of Maine’s special fishing laws and the law book is available online.
You can contact a regional Fisheries Biologists or district Game Warden for help or to report regulation violations.
