Title:Upper Mississippi River fish population monitoring and sport fish assessment in west-central Illinois, 2020
Author(s):DeBoer, Jason A.; Lamer, James T.
Subject(s):large river monitoring
Geographic Coverage:Upper Mississippi River
Abstract:This report presents a summary of data collected during segment 07 (2020-2021) of the Upper Mississippi River fish population monitoring and sport fish assessment in west-central Illinois, an annual survey by staff of the Illinois Natural History Survey, with funds administered by the U.S. Fish and Wildlife Service and the Illinois Department of Natural Resources. Sampling for the program was conducted on 6 navigational pools of the Upper Mississippi River. All fishes collected were accurately identified, counted, measured, and weighed. The catch rates of several key species were calculated as the number of individuals collected per hour (CPUE ± standard error). Proportional size distribution (PSD) was also calculated for several key species. Catch rates and species varied among all sampling locations and sampling periods. Emerald Shiner and Gizzard Shad comprised most the individuals caught, and Common Carp and Channel Catfish accounted for the greatest proportion of the biomass collected.
