A small madtom catfish of rocky streams. Found in a few river systems in southern Michigan. Nocturnal and secretive. Handle carefully — fin spines may sting.
No stocking records are on file for Margined Madtom.
This is common for several reasons: this species may reproduce naturally and not require stocking (e.g. Largemouth Bass, Northern Pike), it may be managed under a different program not tracked here, or records may predate our database. For the most current data, check the Michigan DNR Stocking Database directly.
