The species taken and their relative abundances based on five seine hauls at each station are shown in Table 7. At the uppermost pool (G-17) only small green sunfish were found. At G-16, next downstream, this species was joined by large numbers of black bullheads and a few redfin shiners and red shiners. G-13 was similar to G-16, but two additional species occurred there. G-12 was a clear, deep pool much larger than any at the stations upstream. Here, seven species were added to the fauna, and the percentages of _Ictalurus melas_ and _Lepomis cyanellus_ were much less. At G-10 _Fundulus notatus_, _Labidesthes sicculus_, and _Minytrema melanops_ appeared. Nevertheless, fewer species (10) were captured here than at station G-12 upstream.
