Abstract

The Long Term Resource Monitoring Program (LTRMP) completed collections of fish from stratified random sampling and permanently fixed-site sampling in six study areas of the Upper Mississippi River System. Collection methods included day and night electrofishing, hoop netting, fyke netting (two net sizes), seining, and bottom trawling in selected aquatic area classes. The six LTRMP study areas are Pools 4 (excluding Lake Pepin), 8, 13, and 26 of the Upper Mississippi River, an Open River (unimpounded) reach of the Mississippi River near Cape Girardeau, Missouri, and La Grange Pool of the Illinois River.

For each of the six LTRMP study areas, this report contains summaries by year 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.
