“…For example, our Figure 3 shows the carp moved as far away from the CO 2 barrier as possible. Our results are also in concordance with work by others that found molecular‐level responses to CO 2 in Asian carp and effects on Asian carp behavior (Dennis, Adhikari, & Suski, 2015; Dennis, Kates, Noatch, & Suski, 2015). Furthermore, our approach captured more complex responses than typically assessed in fish movement studies and has the potential to provide insights into fish behavior and response to stressors.…”

Natural resource managers use barriers to deter the movement of aquatic invasive species. Research and development of new invasive species barriers is often evaluated in pond and field scales using high‐resolution telemetry data. Telemetry data sets can be a rich source of data about fish movement and behavior but can be difficult to analyze due to the size of these data sets as well as their irregular sampling intervals. Due to the challenges, most barrier studies only use summary endpoints, such as barrier passage counts or average (e.g., mean or median) fish distance from the barrier, to describe the data. To examine more fine‐scale fish movement patterns, we developed a first‐order Markov chain. We then used this model to help understand the impacts of a barrier on fish behavior. For our study system, we used data from a previous study examining how bighead and silver carp (two invasive fish species in the United States) responded to a carbon dioxide (CO2) barrier in a pond. Considerations for management Based upon our findings, management considerations include: Markov chains can be used to describe and quantify movement patterns of aquatic organisms responding to barriers. These models provide insight not possible with previously used summary approaches. The CO2 barrier changed both the locations of fish and movement patterns of fish. The changes in movement were not captured using conventional endpoints. Specifically, fish had less random movement patterns during periods of CO2 exposure. This provides evidence that bighead and silver carp actively avoided areas with CO2 and also shows that our approach can help assess random versus nonrandom movements

“…However, with any non-physical deterrence strategy, less than 100% deterrence must be an acceptable outcome (Noatch and Suski 2012;Wittman et al 2014). During periods of hypercapnia, fish undergo physiological detriments such as ion imbalance (Claiborne et al 2002), increased stress response (Kates et al 2012), acidosis (Ishimatsu et al 2005), hyperventilation (Perry and Abdallah 2012), hypoventilation (Kates et al 2012), loss of sensory function (Nilsson et al 2012), and changes in protein composition (Dennis et al 2015). In conjunction with elevated CO 2 , a corresponding decrease in pH D r a f t carbon dioxide are reported or derived in terms of pressure (e.g.…”

Resource managers need effective methods to prevent the movement of silver carp (Hypophthalmichthys molitrix) and bighead carp (Hypophthalmichthys nobilis) from the Mississippi River basin into the Laurentian Great Lakes. In this study, we evaluated dissolved carbon dioxide (CO2) as a barrier and deterrent to silver (278 ± 30.5 mm) and bighead (212 ± 7.7 mm) carp movement in continuous-flow outdoor ponds. As a barrier, CO2 significantly reduced upstream movement but was not 100% effective at blocking fish passage. As a deterrent, we observed a significant shift away from areas of high CO2 relative to normal movement before and after injection. Carbon dioxide concentrations varied across the pond during injection and reached maximum concentrations of 74.5 ± 1.9 mg·L–1 CO2; 29 532 – 41 393 μatm (1 atm = 101.325 kPa) at the site of injection during three independent trials. We conclude that CO2 altered silver and bighead carp movement in outdoor ponds and recommend further research to determine barrier effectiveness during field applications.

“…Over time, this pH imbalance is corrected as fish uptake HCO 3 − from the environment (in exchange for Cl − ) and excrete H + (in exchange for Na + ) [63]. Owing to this influx of CO 2 , hypercarbic environments cause an elevation of the general stress response [64][65][66], a drop in blood pH [67], a loss of ions [68], and, ultimately, equilibrium loss and anesthesia (Stage 2 or Stage 3) [64,67,69,70]. At present, the exact mechanism(s) responsible for the loss of equilibrium and the anesthetic impacts of carbon dioxide have not been well defined, but are believed to result from the movement of CO 2 across the blood-brain barrier, which alters brain pH and an impairs brain electrical activity [71,72]; additions of H + or HCO 3 − alone will not result in anesthesia for fish [71].…”

Invasive species are a threat to biodiversity in freshwater. Removing an aquatic invasive species following arrival is almost impossible, and preventing introduction is a more viable management option. Bigheaded carp are an invasive fish spreading throughout the Midwestern United States and are threatening to enter the Great Lakes. This review outlines the development of carbon dioxide gas (CO2) as a non-physical barrier that can be used to deter the movement of fish and prevent further spread. Carbon dioxide gas could be used as a deterrent either to cause avoidance (i.e., fish swim away from zones of high CO2), or by inducing equilibrium loss due to the anesthetic properties of CO2 (i.e., tolerance). The development of CO2 as a fish deterrent started with controlled laboratory experiments demonstrating stress and avoidance, and then progressed to larger field applications demonstrating avoidance at scales that approach real-world scenarios. In addition, factors that influence the effectiveness of CO2 as a fish barrier are discussed, outlining conditions that could make CO2 less effective in the field; these factors that influence efficacy would be of interest to managers using CO2 to target other fish species, or those using other non-physical barriers for fish.
