Growing as large as five feet and over 100 pounds, flathead catfish are one of North America’s largest fresh water fish. Their preferred habitats are deep pools, lakes, and large slow-moving rivers. Within these waters they prefer submerged cover such as logs. Good flathead spots typically include structure, located in relatively deep water ideally with moderate current, and access baitfish. Flatheads typically prey only on live fish.
As their name suggests, they have flat heads, yet they looks similar to other catfish. They come equipped with a smooth, scaleless skin, barbels, and spines on the dorsal and pectoral fins. Flathead are typically yellowish to light brown on the back and sides, with a yellowish to cream belly.
Reaching sexual maturity in three to six year, spawning occurs from late May through August, when the water temperatures reach 75 degrees or better. Flatheads prefer to nest in areas with submerged logs and other debris. Females lay approximately a 1,000 eggs per pound of body mass. After four to six days, the eggs hatch and the fry school together at the nest for several days, where the males guard them aggressively.
