Although popular within its native range, the black crappie is unwelcome in Maine waters. It is now established in parts of three major river drainages .
Profits have overcome the consciences of a number of Maine bait dealers in recent years. Three new species of shiners have been found - probably smuggled in as baitfish .
THE FRESHWATER FISHES OF MAINE-1982 UPDATE Despite tough laws to the contrary, introductions of non-native fish species have increased in recent years. Department biologists have identified no less than five new species in Maine's inland waters since 1977. Here is a list of the freshwater fishes presently known to be firmly established in the state. Not included are anadromous, catadromous, and brackish water species which spend at least part of their lives in salt water or estuaries. KEY:

*The anadromous alewife (Alosa pseudoharengus) is a native Maine species. A landlocked strain of this species was introduced to several Maine lakes from New York by Department biologists in the 1960s and 1970s as a forage species for salmon and trout.
