Abstract : The Long Term Resource Monitoring Program (LTRMP) completed 2,221 collections of fishes from stratified random and permanently fixed sampling locations in six study reaches of the Upper Mississippi River System during I 992. 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 areas 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 LAS Grange Pool of the Illinois River. A total of 56-70 fish species were detected in each study area. For each of the six LTRMP study areas, this report contains summaries of: (1) sampling efforts in each combination of gear type and aquatic area class, (2) total catches of each species from each gear type, ) mean catch per-unit of gear effort statistics and standard errors for common species from each combination of aquatic area class and selected ear type and (4) length distributions of common 5 species from selected gear types.
