Details

The Stone Cat, together with the other madtoms, represents the smallest fish in the catfish family. The Stone Cat spawns in spring and, like all catfish, builds a nest and guards the eggs and young. Madtoms show nocturnal behavior and probably spawn in areas of darkness, like under rocks or in bank hides. The Stone Cat is the largest of the madtoms and lays between 500 and 1,000 eggs at a time. It prefers stream riffle habitats, but is also found under rocks or weedy shorelines of lakes and ponds.

Like most catfish, they are omnivorous and extremely adaptable in seeking food items in ponds and lakes.

Recent stream sampling information is available from Iowa DNR's biological monitoring and assessment program.
