Fox River Basin Management Plan In 1989, the Missouri Conservation Commission approved the Streams for the Future program designed to slow stream degradation and enhance and improve streams and corridors. Basin planning was developed to gather baseline hydrological, geomorphological, and biological information on the state's major stream basins. In 1987, the Fox River Basin was surveyed to assess stream habitat and fish communities. Data from the survey and information assimilated from the literature were used to develop this basin plan. The Fox River Basin drains 400 mi2 in northeastern Missouri and southeastern Iowa upstream of the gage station on the Fox River at Wayland, Missouri. The Fox River is a tributary to the Mississippi River. Approximately... Categories: Publication; Types: Map Service, OGC WFS Layer, OGC WMS Layer, OGC WMS Service
Population Trends of Flathead Catfish, Channel Catfish, and Blue Catfish in Impounded and Unimpounded Reaches of the Upper Mississippi River (1993-2007) Using Long Term Resource Monitoring Program data collected from impounded (Pool 26) and unimpounded (Open River) reaches of the upper Mississippi River, we investigated population dynamics of flathead catfish Pylodictis olivaris, channel catfish Ictalurus punctatus, and blue catfish I. furcatusfrom random sites located in side channel border (SCB) and main channel border (MCB) habitats. Objectives were to (1) compare trends (1993–2007) of three catfishes collected in Pool 26 and Open River reaches of the upper Mississippi River, and (2) provide needed information to managers on population dynamics through time using a binary gear approach of active (i.e., daytime electrofishing) and passive gears (hoopnetting)....

Distributional status of uncommon fishes and an amphibian from northeastern Missouri The distribution of Missouri fishes is well documented in the Fishes of Missouri. However, prairie streams in Missouri have not been sampled as intensively as Ozark streams probably because the fauna is less rich and diverse. In the mid-1980s, the Missouri Department of Conservation implemented a program (Streams for the Future) to improve the awareness and understanding of Missouri streams. Several important products are resulting from this work, one of which is a better understanding of fish distribution in the state. In my paper, I describe new distributional records for eight species of fish and one species of amphibian from the glaciated till plains of northeastern Missouri and comment on the conservation status...

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

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
