Spotted Sucker

Spotted Sucker

The Spotted Sucker is a native Minnesota fish species found in the lower Great Lakes and Mississippi River basins from Pennsylvania to Minnesota.

In Minnesota, they're considered functionally extirpated from much of their historic range, particularly in the Minnesota River basin where they were once present but may now be functionally gone along with other large river species like River Redhorse and Western Sand Darter.

Scientific Name: Minytrema melanops

Physical Characteristics:

These medium-sized suckers are distinguished by 8-12 parallel rows of dark spots at the base of each scale, giving them their characteristic spotted appearance. They can reach up to 19 inches and live approximately 6 years, maturing at age 3.
