Mussel Density Quadrat Sampling Locations in West Newton Chute from 2008 to 2017

Since 2008, over 1,400 quadrats and about 2,500 mussels have been systematically sampled within West Newton Chute (WNC), contributing to a diverse assemblage of 25 live species, including 2 federally endangered species, and 10 Minnesota listed species. West Newton Chute is a 2.4 km long side channel in Navigation Pool 5 of the Upper Mississippi River and has an overall aquatic area of ~75 ha....

Auditory thresholds for bighead and silver carp after sound exposure determined by the AEP technique: Data

Invasive silver (Hypophthalmichthys molitrix) and bighead (H. nobilis) carp, collectively referred to as bigheaded carps, threaten aquatic ecosystems of the Upper Midwestern United States. Due to extensive ecological impacts associated with these species, prevention of their further range expansion is the aim for fisheries management. Recent behavioral studies indicate bigheaded carps are...

Conserving Minnesota’s native mussel legacy: Quantifying habitat interactions

The goal of this project was to quantify the background physiological condition of mussels in the Minnesota and St. Croix River basins using glycogen as an indicator of physiological stress. We obtained 230 samples of foot tissue from Lampsilis cardium (n=118) and Lasmigona complanata (n=112) from a total of four rivers during September 1-5, 2015. From each sample, we weighed out a 10.0 &#...

Upper Mississippi River-Pool 4 Time Lag Investigation of Physical Conditions and Submersed Macrophyte Prevalence: Data

The Long-Term Resource Monitoring element (LTRM) of the Upper Mississippi River Restoration program (UMRR) has conducted aquatic vegetation and water quality surveys in several navigation pools since the mid 1990’s. Over a 20-year period (1998-2017), the off-channel (i.e. backwater) areas in upper Pool 4 remained chronically turbid and supported a limited submersed macrophyte...
