Summary
The Long Term Resource Monitoring Program (LTRMP) completed 2,664 collections of fishes from stratified random and permanently fixed sampling locations in six study reaches of the Upper Mississippi River System during 1998. Collection methods included day and night electrofishing, hoop netting, fyke netting (two net sizes), gill netting, seining, and trawling in select aquatic area classes. The six LTRMP study reaches are Pools 4 (excluding Lake Pepin), 8, 13, and 26 of the Upper Mississippi River, an unimpounded reach of the Mississippi River near Cape Girardeau, Missouri, and the La Grange Pool of the Illinois River.

Summary
The Long Term Resource Monitoring Program (LTRMP) completed 2,664 collections of fishes from stratified random
and permanently fixed sampling locations in six study reaches of the Upper Mississippi River System during 1998. Collection
methods included day and night electrofishing, hoop netting, fyke netting (two net sizes), gill netting, seining, and trawling in select
aquatic area classes. The six LTRMP study reaches are Pools 4 (excluding Lake Pepin), 8, 13, and 26 of the Upper Mississippi River,
an unimpounded reach of the Mississippi River near Cape Girardeau, Missouri, and the La Grange Pool of the Illinois River. A total
of 63–75 fish species were detected in each study reach. For each of the six LTRMP study reaches, this report contains summaries
of (1) sampling efforts for each combination of gear type and aquatic area class, (2) total catches of each species from each gear type,
(3) mean catch-per-unit of effort statistics and standard errors for common species from each combination of aquatic area class and
selected gear type, and (4) length distributions of common species from selected gear types.
