Abstract

The Ohio River Basin, including the Ohio, Cumberland, and Tennessee rivers, and the contiguous Tennessee - Tombigbee Waterway are under threat due to the ongoing invasion of bigheaded carps. In the Tennessee River, bigheaded carps were first documented in Kentucky Lake in 2004. I tested whether there were differences in abundance of Gizzard Shad, a competitor, before and after the bigheaded carps invasion, but no effects were detected. I also surveyed bigheaded carps colonization of Bay Springs Lake in the Tennessee - Tombigbee Waterway. Catch rates with gillnets were low and conformed with those documented elsewhere in the Ohio Basin considering distance from the Mississippi River.
