During 1990, the fisheries component of the Long Term Resource Monitoring Program (LTRMP) conducted standardized sampling in Pools 4, 8, 13, and 26 of the Upper Mississippi River and La Grange Pool of the Illinois River. Fixed sampling sites from up to nine habitat classes were surveyed by seining, small 'minnow' fyke netting, electrofishing, fyke netting, and hoop netting during two fish community sampling time periods (June 25 to August 3 and August 1 to September 17) and three special efforts to sample black crappie (Pomoxis nigromaculatus), channel catfish (Ictalurus punctatus), and sauger (Stizostedeon canadense). Differences in fish community structure across pools and habitat classes were tested using multivariate analysis of variance models fitted to data from each sampling gear
