Warmouth

Warmouth (Lepomis gulosus) in Arkansas are stocky, bass-like sunfish belonging to the Centrarchidae family. These fish are native to Arkansas and found throughout the Mississippi River drainage system.

They are remarkably hardy, surviving in low-oxygen, polluted waters where other sunfish cannot, making them common in muddy bottom environments.

  • Typically range from 4-10 inches long but can exceed 12 inches and reach 2.25 pounds.
