Summary

Data set includes water Sr:Ca, Ba:Ca, and δ18O for the Upper Mississippi River and tributaries and otolith Sr:Ca, Ba:Ca, and δ18O data from bigheaded carp collected in pools 19-21 of the Upper Mississippi River. Abstract from manuscript: Knowledge of environments used during early life history and movement patterns of Bighead Carp (Hypophthalmichthys nobilis) and Silver Carp (H. molitrix), collectively termed bigheaded carps, in the Upper Mississippi River (UMR) would be valuable for informing control measures to limit further population expansion and impacts of these species. Lock and Dam 19 (LD19) is a high-head dam on the UMR that delineates downriver areas where bigheaded carps are well-established from upriver pools where these [...]

Purpose

Data were collected to: 1) characterize multivariate water chemistry signatures (Sr:Ca, Ba:Ca and δ18O) among the Upper Mississippi River, its tributaries, and the Missouri and Middle Mississippi rivers; 2) infer environments occupied during early life stages by bigheaded carps collected in Upper Mississippi River Pools 19-21 using otolith microchemistry and stable isotope analyses, and (2) use early life environment assignments and capture location to identify individuals that passed through Lock and Dam 19. Water chemistry data will be potentially useful as baseline data for studies using calcified structure chemistry to infer environmental history of other fish species in the Upper Mississippi River. Bigheaded carp otolith chemistry data and data on early life environments of fish sampled for this project will potentially be useful for future studies to assess how early life environments supporting recruitment of these species in the Upper Mississippi River may have changed over time.
