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
