Table 1. Comparison of species richness and Alternate Index of Biotic Integrity (AIBI) values from fish samples collected in
Middle Kaskaskia River watershed, 1983 and 1997. All mainstream river sites sampled with boat electrofishing.* Tributary sites
sampled with rotenone in 1983 and electric seine in 1997.**

*Numbers in parentheses include additional spp taken in 1997 with minnow seine hauls (seine not used in 1983 sampling).
** Big Ck (OP-01) and Wolf Ck (OPC-01) were sampled entirely with minnow seine in 1997 due to high conductivity.
