1995 Annual Status Report: A summary of fish data in six reaches of the Upper Mississippi River System The Long Term Resource Monitoring Program (LTRMP) completed 2,723 collections of fishes from stratified random and permanently fixed sampling locations in six study reaches of the Upper Mississippi River System during 1995. 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 59–72 fish species were detected in each study reach. For each of the six LTRMP study... Categories: Publication; Types: Map Service, OGC WFS Layer, OGC WMS Layer, OGC WMS Service

Spatial, temporal, and environmental trends of fish assemblages within six reaches of the Upper Mississippi River System We investigated differences in adult and young-of-the-year (YOY) fishes within each of the six Long Term Resource Monitoring Program study areas, using monitoring data from 1993 to 2001. Our objective was to investigate the relative roles of seasonal, annual, in situ, and physical habitat factors in explaining assemblage structure patterns within the Long Term Resource Monitoring Program study areas. Adult and YOY assemblage structure within each reach was dominated by one to three numerically abundant species. The percent of the total abundance for which these species accounted was 10–88% and varied among age classes and study areas. Physical habitat classes were only weakly associated with differences in fish... Categories: Publication; Types: Map Service, OGC WFS Layer, OGC WMS Layer, OGC WMS Service
An investigation of fish community and water quality compositions in an isolated side channel of the upper Mississippi River Varying degrees of connectivity between side channels and the main river channel are vital for sustainable ecological processes and functions for both aquatic and terrestrial communities. Within the Mississippi River, restoring side channel functional diversity is a top priority for many natural resource agencies. Buffalo Chute, located at river kilometer 41, is one of the several side channels, island complexes that becomes isolated from the main channel during low river stages leading to thermal and chemical stratifications and anoxic conditions. The purpose of this study was to better understand the impacts of side-channel isolation in the middle Mississippi River (MMR) by measuring fish community and water quality...
