Field evaluation of carbon dioxide as a fish deterrent at a water management structure along the Illinois River: Data
Resource agencies are searching for effective methods to prevent the spread of invasive Silver Carp (Hypophthalmichthys molitrix) and Bighead Carp (Hypophthalmichthys nobilis), hereafter bigheaded carps, from the Mississippi River basin into the Laurentian Great Lakes. Elevating carbon dioxide (CO2) concentrations in water within locks and other pinch points is an approach being considered to reduce invasive fish passage. Laboratory studies have shown that bigheaded carps strongly avoid areas of elevated CO2 (Kates et al. 2012; Dennis et al. 2015). Similarly, telemetry studies found that CO2 can be used to exclude bigheaded carps from certain locations (Donaldson et al. 2016) and reduce upstream movement (Cupp et...
Evaluating upstream passage and timing of approach by adult bigheaded carps at a gated dam on the Illinois River:Data
To evaluate how bigheaded carps move upstream through and around Starved Rock Lock and Dam (SRLD) on the Illinois River, their movements were monitored using acoustic telemetry. This dataset describes the results of this study and was used to compare the residency duration of upstream migrants downstream of SRLD between years, tailwater elevation, and water temperature, and how tailwater elevation and water temperature influenced their timing of arrival downstream of SRLD. Calculation of passage and residency are available in the thesis of Matthew Lubejko (Southern, Illinois University, 2016).
