Otolith microchemistry of adult bigheaded carp for determining early-life environments in the Upper Mississippi River 2016-2018 Data set includes water Sr:Ca, Ba:Ca, and δ18O for the Mississippi River and tributaries, and otolith Sr:Ca, Ba:Ca, and δ18O data from bigheaded carp (Silver Carp and BIghead Carp) collected in navigation pools 16-19 of the Upper Mississippi River in 2016 to 2018. Bigheaded carp (Bighead Carp and Silver Carp) are invasive species in the US and have spread throughout most of the lower Mississippi River Basin. Population abundance upstream of Lock and Dam 19 (LD19) on the Upper Mississippi River (UMR) has likely been limited by the high-head dam at this location, which restricts all upstream fish passage to the lock chamber. To determine early-life environments of adult bigheaded carp captured upstream LD19 at the...

Data release associated with research that describes how major flooding and dam operations in the upper Mississippi River contribute to large upstream migrations of native paddlefish and invasive bigheaded carp Recent research has attributed major flood events with the upstream spread of invasive carp in the Mississippi River. In two sequential years, the upper Mississippi River experienced a low water year with very minimal flooding in 2022 and a very high water year with extreme and sustained flooding in the spring of 2023. This data release contains hydrologic data from the U.S. Army Corps of Engineers at upper Mississippi River navigation locks 4-18 to classify when each dam experienced open river conditions and was no longer preventing upstream movements of fishes. To attribute biological movements around these open river conditions, we used acoustic telemetry data to track native paddlefish and invasive bigheaded...

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.
