These data was collected in conjuction with Upper Mississippi River Restoration-Long Term Resource Monitoring (UMRR-LTRM) element data. The goal of this data collection was to assess age structure of smallmouth buffalo Ictiobus bubalus in the Upper Mississippi River system. Through ongoing UMRR-LTRM efforts, we collected fish with a goal 10 smallmouth buffalo from 20mm length groups, beginning at 100mm of total length. Upon collection fish were measured, weighed and frozen, then transported to the Illinois River Biological Station in Havana Illinois. Upon completion of fish collection, fish were thawed and both lapillus otoliths were removed and a sex determination was made via visual inspection of the gonads. Lapillus...

The Long Term Resource Monitoring (LTRM) annual fish monitoring began on the Upper Mississippi and Illinois Rivers in 1989. During the first two years samples were collected at a series of fixed sampling sites, then in 1993 a stratified random sampling approach was added to the collection effort. This approach utilizes a computer routine that randomly selects sampling sites from a pool of potential sites that have been categorized by strata (e.g., aquatic habitat type, distance to shore, connectivity to main channel). The results from these collections are stored in an Oracle database at the Upper Midwest Environmental Science Center (UMESC). UMESC provides free access to the data through the Centers Web site (www.umesc.usgs.gov)....

The Long Term Resource Monitoring Program (LTRMP), a component of the Environmental Management Program for the Upper Mississippi River System (UMRS), is funded by the U.S. Army Corps of Engineers and administered by the U.S. Geological Survey's Upper Midwest Environmental Sciences Center (Center) in La Crosse, Wisconsin. The LTRMP supports six field stations operated by state agencies in Illinois, Iowa, Minnesota, Missouri, and Wisconsin ( Figure 1) to collect most of the monitoring data. Data on important ecosystem components, including water quality, vegetation, macroinvertebrates, and fish, are obtained using standardized operating procedures. Monitoring activities focus primarily on six study areas: Navigation...

This dataset includes two series of data. The first series contains growth model coefficients for >90 fish species in the Upper Mississippi River System (UMRS). These models were fit form empirical length and weight data observed from 1993-2007 during routine annual scientific monitoring of the UMRS fish community under a federal/state partnership program known as the Upper Mississippi River Restoration (UMRR) program (see: https://umesc.usgs.gov/ltrm-home.html, accessed 3/18/2020). To achieve growth model coefficients for each fish species, length and weight data were log10 transformed and fit using statistical regression techniques (Proc GLM in SAS v 9.4). Model coefficients representing the regression y-intercept,...
