How to fish for margined madtom

Margined madtom are a small, secretive catfish of clean, rocky streams and rivers, hiding under stones and debris by day and feeding on invertebrates at night. Like other madtoms they have venomous pectoral spines that deliver a bee-sting-like jab if handled carelessly. They aren't an angling target - they're a forage fish, prey for smallmouth bass and other stream predators, and a favorite bait among those who know to use them. On a location page, margined madtom are a forage species tied to clean, rocky-bottomed flowing water.
