“…Our results demonstrate the widespread nature of barotrauma‐related impairment in angled fish, which, in the context of ice‐angling, may compound the unique physiological challenges already faced such as reduced metabolic recovery rates and tissue freezing (Card et al, 2022; Winter et al, 2018). Fish in our study were captured from generally shallower depths than in prior studies (Ferter et al, 2015; Pribyl et al, 2012; Rudershausen et al, 2014), but we still found that swimming was impaired by gas expansion in bluegill and black crappie.…”

Barotrauma can lead to physical injury and physiological disturbance (elevated stress hormones, and depleted energy stores during post-release struggling) in angled fish.Effectiveness of methods for reducing effects of barotrauma on fish has not been tested on fish subjected to ice-angling. We examined post-release behavior and redescension of bluegill Lepomis macrochirus and black crappie Pomoxis nigromaculatus.Barotrauma was mitigated for fish either during capture by slow retrieval or following capture by venting or re-descension with weights, before observation in a behavioral arena or using small acceleration and depth biologgers. Black crappie spent less time in the center of the behavioral arena and were less likely to successfully re-descend than bluegill. Depth increased over time during the post-release monitoring period, with control fish less likely to descend to depth as fish for which barotrauma was mitigated. Our results demonstrate species-specific effects of ice-angling to inform anglers on the effectiveness of barotrauma mitigation strategies to improve welfare of fish after release.

“…The gills of fish in our study did not show changes that have been commonly observed in environmental studies. Specifically, aneurysms forming at the end of the secondary lamellae and gill fusion have been reported in other species when exposed to toxins (Spies et al 1996;Teh et al 1997;Noor et al 2019) and ice (Card et al 2022).…”

Objective The broad objective of our study was to use a histological approach to examine possible tissue‐level effects of exposure to elevated CO2 in freshwater young‐of‐year salmonids. Methods To study these effects, young‐of‐year Arctic Char Salvelinus alpinus, Rainbow Trout Oncorhynchus mykiss, and Brook Trout S. fontinalis were exposed to either control levels of CO2 (1400 μatm) or elevated levels of CO2 (5236 μatm) for 15 days. Fish were then sampled for gill, liver, and heart tissues and histologically analyzed. Result A species effect was observed for the length of secondary lamellae, as Arctic Char had significantly shorter secondary lamellae than the other species. No notable changes within the gills and livers of Arctic Char, Brook Trout, or Rainbow Trout exposed to elevated CO2 were observed. Conclusion Generally, our results indicated that elevated CO2 levels over 15 days do not induce catastrophic tissue damage and it is unlikely that fish health would be seriously impacted. Ongoing research dedicated to examining how elevated CO2 long‐term may affect internal tissues of fish will allow for a more comprehensive understanding of how fish may fair with ongoing climate change and in aquaculture facilities.

“…2015), and how this slower healing rate influences long‐term outcomes for fish is unclear. To date, no research has characterized healing rates of tissue damage in ice‐angled fish, although some groups have started to characterize the potential effects of subfreezing temperature exposure on various tissues (Card et al., in press). As more is learned about fish physiology during the winter, best practices for reducing the negative consequences of angling should be developed.…”

Catch‐and‐Release Ice Fishing: Status, Issues, and Research Needs

Catch-and-release (C&R) ice fishing is a popular form of recreational angling. At present, there is a considerable deficiency in our understanding of how ice angling affects the physiology, behavior, and survival of fish. Thus, the purpose of this review was to summarize our current knowledge of the consequences of winter C&R fishing on fish biology and to identify key knowledge gaps. Our synthesis revealed that in addition to the typical stressors encountered from C&R fishing during the open-water season, fish that are caught through the ice are subject to several unique challenges, including exposure to subzero air temperatures upon landing as well as unique gear types that are not commonly used in the summer (i.e., passive angling techniques). We currently understand that while C&R angling causes a generalized stress response, cold environments may mute or delay these effects and may also come with additional deleterious consequences, such as tissue freezing. Interestingly, reported mortality can be low following release but can be influenced by gear type, barotrauma, and hooking location. Postrelease behaviors and the spatial ecology of ice-angled fish are poorly understood, but technologies such as telemetry and biologgers and an intensification of research on the topic are starting to produce new insights in this area. As it stands, research on the consequences of winter C&R angling is largely restricted to a handful of popular sport fish species, and these consequences are likely
