Upper Midwest Environmental Sciences Center
2003 Report
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 electrofishing, hoop netting, fyke netting (two net sizes), 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. In 2003, sampling was reduced to only day electrofishing for the three northern study reaches because of budget reductions. Funding from the National Great Rivers Research and Education Center, the Illinois Department of Natural Resources, and the Missouri Deptartment of Conservation allowed for complete LTRMP fish monitoring in Pool 26, Open River, and La Grange Pool (all gears, all sampling periods).
