Resource managers need effective methods to limit the spread of invasive Asian carps (Hypophthalmichthys spp.) into new areas. This study evaluated carbon dioxide (CO2) as a barrier and deterrent to Asian carps in a small outdoor pond. Telemetered silver carp (Hypophthalmichthys molitrix) and bighead carp (Hypophthalmichthys nobilis) were monitored for 72h (24h before CO2, 24h during CO2, 24h after CO2) using a two-dimensional acoustic telemetry array to evaluate behavioral responses to CO2. Water quality was measured concurrent with acoustic telemetry to determine the concentration and extent of the CO2 plume. Results are intended to provide information on the potential application of CO2 as an invasive fish deterrent strategy.

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 al. 2016). Previous studies were completed under controlled settings, and research to determine the feasibility and efficacy of elevated CO2 to control bigheaded carp movements in larger natural environments is needed. On October 21–28, 2016, the U.S. Geological Survey Upper Midwest Environmental Sciences Center, Illinois-Iowa Water Science Center, and Columbia Environmental Research Center conducted a short field study at Emiquon Preserve (15T 750386.95m E, 4469041.70m N) near Havana, IL. Objectives for this study were to (1) characterize CO2 concentrations and distribution at various water velocities and (2) determine the effectiveness of CO2 to reduce general fish abundance and movement. During this study, water quality, atmospheric CO2, and fish presence were quantified across three water velocities (no flow, restricted flow, and unrestricted flow) with and without CO2 injection. The study was conducted at the water management structures (WMS) which served at the single connection between an isolated backwater lake and the Illinois River. Carbon dioxide was injected into the downstream portion of the WMS using air diffusers connected to compressed CO2 tanks. Fish abundance and movement was quantified using two Adaptive Resolution Imaging Sonar (ARIS) transducers placed across WMS entrances. Water quality was quantified using stationary sondes, grab sample, and mobile transects. Atmospheric CO2 concentrations were quantified at fixed locations throughout the study site. Dates and times of importance: no water flow with CO2 start (21OCT2016 0800 CDT) and stop (21OCT2016 1600 CDT), modified flow with CO2 start (25OCT2016 0800 CDT) and stop (25OCT2016 1600 CDT), unrestricted flow with CO2 start (24OCT2016 0800 CDT) and stop (24OCT2016 1600 CDT), no flow control day without CO2 (28OCT2016), modified flow control day without CO2 (27OCT2016), and unrestricted flow control day without CO2 (23OCT2016).

This dataset accompanies the article "Upstream experience and experimental translocation of invasive bigheaded carps results in increased upstream passage success at a navigation lock in a large river". The data come from the experimental capture and tagging of invasive bigheaded carp with acoustic transmitters and physically moving some groups farther downstream. These transmitters emit signals that are detected and recorded on receivers that are strategically placed above, within, and below Mississippi River Lock and Dam 19 (LD 19). Once the data from the receivers were downloaded, we could show when successful upstream passage through LD19 occurs and compare the origin of the fish and the physical characteristics recorded at the time of tagging. The shipping industry and barge movement data were also included in summaries to evaluate how traffic around these navigation barriers may be preventing or assisting fish movements. To ensure data were being collected with confidence, periodic field testing of the acoustic receiver were performed and included in the final study materials.

This dataset accompanies the article "Off-channel habitat use by silver carp (Hypophthalmichthys molitrix) and bighead carp (H. nobilis) in the upper Mississippi River". Acoustic telemetry data (Innovasea, Inc.) were collected on invasive silver carp (Hypophthalmichthys molitrix) and bighead carp (Hypophthalmichthys nobilis) in Pools 17-19 of the upper Mississippi River to examine timing and environmental conditions associated with off-channel habitat use during 2017–2018. Data also include surface water velocity, water temperature, dissolved oxygen, and dam discharge from Lock and Dam 19.

The dataset and accompanying analysis scripts accompany the article "Bayesian multistate models allow incorporation of spatial dynamics to improve invasive species management". The data are summarized detections from acoustic telemetry receivers (69 KHz) from 353 silver carp (Hypophthalmichthys molitrix) and 170 bighead carp (H. nobilis) surgically implanted with transmitters in the Illinois River, USA. The analysis scripts assess probability of detection, probability of monthly movement between navigation pools on the river, probability of apparent survival, and probability of operable transmitter battery through a Bayesian multistate hidden Markov model.
