  Flathead 
              catfish are typically pale yellow to light brown on the back and 
              sides, and highly mottled with black and/or brown. The belly is 
              usually pale yellow or cream colored. The head is broadly flattened, 
              with a projecting lower jaw. The tail fin is only slightly notched, 
              not deeply forked as is the case with blue and channel catfish. 
              Young fish may be very dark, almost black in appearance.
 The 
              native range includes a broad area west of the Appalachian Mountains 
              encompassing large rivers of the Mississippi, Missouri, and Ohio 
              basins. The range extends as far north as North Dakota, as far west 
              as New Mexico, and south to the Gulf including eastern Mexico.  Fishermen 
              began catching flatheads in the Ocmulgee River near Macon in the 
              early 1970s. Since then, they have spread down the Ocmulgee and 
              Altamaha rivers and upstream on the Oconee River to the Lake Sinclair 
              dam at Milledgeville. Voracious feeders, flatheads have decimated 
              the populations of redbreast sunfish, and have almost wiped out 
              the bullhead catfish.  In 
              1988, state researchers caught an average of 44 pounds of flathead 
              catfish an hour on the Altamaha River; in 1996, that average was 
              594 pounds, at an average of 8 pounds per fish. In 1988, researchers 
              caught an average of 105 redbreast sunfish an hour on the Altamaha 
              compared with 1996 when they averaged 70 per hour.  |
