Warmouth can live in warmer, shallower areas than most other sunfish. These fish are mostly populated in the southeastern part of the U.S. They are not as common as other sunfish because of their low reproductive rates. Because of its coloring, many anglers confuse warmouth with rock bass. Warmouth will average 7 to 8 inches, although 10 to 11 inch fish are not uncommon. A two pound fish would be close to the world record. They feed on insects, crayfish and tiny bait fish.
Everything we cover in our sunfish section as far as catching sunfish will work with the warmouth. These fish do have a decent-sized mouth which allows them to each some bigger baits than some sunfish would, so don’t be shocked if you catch one of these fish while using a tube or small bass jig.
