Gutreuter, S., R. W. Burkhardt, M. Stopyro, A. Bartels and E. Kramer (1998). Annual Status Report, 1991. A Summary of Fish Data in Six Reaches of the Upper Mississippi River System. Long Term Resource Monitoring Program. United States Geological Survey, Report LTRMP-98-P001.
The Long Term Resource Monitoring Program (LTRMP) completed 2,053 collections of fishes from permanently fixed sampling locations in six study reaches of the Upper Mississippi River System during 1991. 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 La Grange Pool of the Illinois River. For each of the six LTRMP study areas, this report contains summaries of: (1) sampling efforts in each combination of gear types and aquatic area class, (2) total catches of each species from each gear type, (3) mean catch-per-unit of gear 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.
