On-Going Improvements in the Sport Fish of the Illinois River

Research output: Chapter in Book/Report/Conference proceedingConference contribution


The fish community in the Illinois River has been monitored from 1957 to the present, yielding a unique opportunity to examine trends in fish populations across six decades. One of the most prominent trends shown in the long-term monitoring is a strong increase in sport fish populations along the length of the Illinois River. Although sport fish demonstrated an overall increase throughout the river, there were differences in both the strength of the improvement and its timing. The greatest improvements in sport fish occurred in the more upstream reaches of the river, which occurred as water quality improved.
