CPUEfj was only 1 .80 Common carp ranked third with a CPUEf, of 36.36 (1 1.5% of 

 the total). Carp have ranked 1-3 in La Grange Reach during every segment of 

 project F-101-R except 1991. 



Peoria (middle river). Eleven species accounted for 95.0% of the total catch 

 in Peoria Reach (Tables 6 and 7). Overall, CPUE.j was 249.88 in 1996. This catch 

 rate is the second highest observed at this reach since 1 989 (CPUE^j was 291 .00 in 

 1995) (Lerczak et al, 1994, 1995, and 1996). In 1995, the highest CPUE^j for all 

 species was 1 50.75 for gizzard shad, which made up 60.3% of the total fish 

 collected in this reach. The gizzard shad catch rate of Peoria Reach was higher 

 than that of all other reaches and was also relatively high in 1995 (CPUEfj was 

 125.86). Bluegill ranked second with a CPUE,.j of 23.75 (9.5% of the total), and all 

 other species made up only 6% or less of the total catch in Peoria Reach. The 

 bluegill catch rate was slightly lower than in other recent years. (CPUEfj has been 

 31.94 or greater since 1992). 



Starved Rock (upper river). Six species accounted for 96.5% of the total 

 catch in Starved Rock Reach (Tables 6 and 7). Overall, CPUE^j was 148.50 in 1996. 

 This catch rate is much lower than the overall CPUEfj of 867.50 observed in 1995, 

 but is higher than all other years of project F-1 01 -R for StaPv'ed Rock Reach 

 (Lerczak et al, 1994, 1995, and 1996) High CPUEfj in 1995 was primarily due to 

 gizzard shad and an abundance of emerald shiner and several other cyprinids. In 

 1996, the highest CPUE,, for all species was 109,00 for gizzard shad, which made 

 up 73.4% of the total fish collected in this reach. Emerald shiner ranked second by
