“…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.…”

“…Spatial analyses designed to discriminate among such possibilities were beyond the scope of this study but could be fruitful endeavors for future work. Together, our results agreed with previous findings that CO 2 barriers are avoided by Asian carp (Dennis, Adhikari et al, 2015; Donaldson, Amberg, & Adhikari, 2016) but provide much more detailed spatial and temporal information on their avoidance behavior.…”

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

“…We then compared our results to previous studies that identified a variable stress response in studied larval fish exposed to increased p CO 2 , all of which were target gene studies using Q-PCR or protein assays. When investigating the expression patterns of HSP70 in whole fry (8 days post fertilization) of big head carp ( Hypophthalmichthys nobilis ) and silver carp ( H. molitrix ) in response to extreme p CO 2 levels (43000 µtam) in freshwater, only larvae from the latter species showed an upregulation in HSP70 39 . Nevertheless, such p CO 2 levels are not possible in most parts of the oceans.…”

“…Although a small number of studies have examined gene expression in fish larvae in response to ocean acidification, these studies have been limited to candidate genes related to stress response 39 or acid-base regulation 13 , which did not allow for the identification of potentially important genes and pathways under differential expression when exposed to simulated ocean acidification. To our knowledge, this is the first study that addresses the effect of OA on the whole transcriptome of marine fish larvae comparing different developmental stages.…”

Ocean acidification (OA), a direct consequence of increasing atmospheric CO2 concentration dissolving in ocean waters, is impacting many fish species. Little is known about the molecular mechanisms underlying the observed physiological impacts in fish. We used RNAseq to characterize the transcriptome of 3 different larval stages of Atlantic cod (Gadus morhua) exposed to simulated OA at levels (1179 µatm CO2) representing end-of-century predictions compared to controls (503 µatm CO2), which were shown to induce tissue damage and elevated mortality in G. morhua. Only few genes were differentially expressed in 6 and 13 days-post-hatching (dph) (3 and 16 genes, respectively), during a period when maximal mortality as a response to elevated pCO2 occurred. At 36 dph, 1413 genes were differentially expressed, most likely caused by developmental asynchrony between the treatment groups, with individuals under OA growing faster. A target gene analysis revealed only few genes of the universal and well-defined cellular stress response to be differentially expressed. We thus suggest that predicted ocean acidification levels constitute a “stealth stress” for early Atlantic cod larvae, with a rapid breakdown of cellular homeostasis leading to organismal death that was missed even with an 8-fold replication implemented in this study.

“…A variety of specialized "lures," glochidial packets (conglutinates), and behaviors have evolved in each unionid species to attract a host fish to the female, increasing the likelihood of successful glochidial attachment to the host (McMahon 1991;Haag 2012). Carbon dioxide is an effective deterrent for fish (Clingerman et al 2007;Kates et al 2012;Dennis et al 2015) and could disrupt the interaction of mussel and host fish during the glochidial release period. Behavioral responses (i.e., gaping and unburial) of juveniles to CO 2 were more frequent at 20°C compared to 5°C and could also increase their risk of predation or displacement.…”

Zebra mussels (Dreissena polymorpha) have exacerbated the decline of native freshwater mussels (order Unionida) in North America since their arrival in the 1980s. Options for controlling invasive mussels, particularly in unionid mussel habitats, are limited. Previously, carbon dioxide (CO 2) showed selective toxicity for zebra mussels, relative to unionids, when applied in cool water (12°C). We first determined 96-h lethal concentrations of CO 2 at 5 and 20°C to zebra mussels and responses of juvenile plain pocketbook (Lampsilis cardium). Next, we compared the time to lethality for zebra mussels at 5, 12, and 20°C during exposure to partial pressure of CO 2 (PCO 2) values of 110 to 120 atm (1 atm = 101.325 kPa) and responses of juvenile plain pocketbook and fragile papershell (Leptodea fragilis). We found efficacious CO 2 treatment regimens at each temperature that were minimally lethal to unionids. At 5°C, plain pocketbook survived 96-h exposure to the highest PCO 2 treatment (139 atm). At 20°C, the 96-h lethal concentration to 10% of animals (LC10) for plain pocketbook (173 atm PCO 2 , 95% CI 147-198 atm) was higher than the LC99 for zebra mussels (118 atm PCO 2 , 95% CI 109-127 atm). Lethal time to 99% mortality (LT99) of zebra mussels in 110 to 120 atm PCO 2 ranged from 100 h at 20°C to 300 h at 5°C. Mean survival of both plain pocketbook and fragile papershell juveniles exceeded 85% in LT99 CO 2 treatments at all temperatures. Short-term infusion of 100 to 200 atm PCO 2 at a range of water temperatures could reduce biofouling by zebra mussels with limited adverse effects on unionid mussels.
