“…The lack of research on the response of fish to winter capture can be attributed to a variety of factors, including the uncomfortable working environment at low temperatures, the difficulty of capturing fish and issues in keeping equipment functional ( Lavery, 2016 ). As a result, there is a paucity of studies on the physiological responses of freshwater fish to catch-and-release in cold winter conditions (but see Louison et al, 2017 ), save for examinations of post-release mortality ( Dubois et al, 1994 ; Persons and Hirsch, 1994 ).…”

“…Currently, knowledge of the ecology and physiology of fish in the winter lags behind knowledge of fish biology in warmer seasons (Lavery ). Indeed, nearly all studies of the sublethal consequences of capture and release on fish have been performed during warm weather periods.…”

Understanding how released fish recover following capture is vital information for researchers examining the effects of angling on exploited populations. This information is virtually non‐existent for fish angled through the ice in winter, despite the popularity of ice‐angling in many northern areas. To address this gap, 60 northern pike, Esox lucius L., were angled through the ice from an impoundment in eastern Wisconsin, USA, and subjected to one of ten combinations of handling and recovery duration. Plasma samples were collected and analysed for cortisol, lactate and glucose. The results showed a delayed response in the elevation of plasma variables, and a significant interaction between air exposure and recovery time for plasma lactate. No fish suffered mortality during the period of holding. Collectively, these data suggest that northern pike are physiologically resilient to ice‐angling capture stress as long as air exposure times are kept at 4 min or less.

“…Although cooler temperatures are suggested to decrease mortality following C&R (reviewed by Gale et al. ), most studies have been conducted almost exclusively in spring, summer, and fall, with less attention paid to winter, when temperatures are extremely cold (Lavery ). Angling of fish through ice is a unique stressor given that ambient environmental temperatures can be very cold.…”

Natural resource agencies have developed catch-and-release regulations for Walleyes Sander vitreus of prohibited size and number to reduce mortality in many recreational fisheries. The efficacy of such regulations is contingent upon the released fish surviving, but survival data on Walleyes captured by ice-angling are lacking. We estimated the survival of Lake Nipissing (Ontario, Canada) Walleyes that were captured by both active and passive ice-angling methods using a variety of hook types and lures baited with Emerald Shiners Notropis atherinoides. We also assessed the role of de-hooking methods on the survival of deeply hooked Walleyes. After the angling event, Walleyes (n = 260) were held for 24 h in a submerged holding pen to estimate postrelease survival. Average mortality after the 24-h holding period was 6.9%. Fewer Walleyes captured by active angling were deeply hooked (9.3%) than passively caught fish (50.4%), and deeply hooked Walleyes were observed to have more frequent postrelease mortality (14.8%) than shallow-hooked Walleyes (3.0%). There was no significant difference in mortality rates of Walleyes caught by passive angling (9.8%) or active angling (2.8%); mortality rates of fish caught on circle hooks (6.1%), J-hooks (8.2%), and treble hooks (5.6%) also did not differ. Neither air temperature nor the presence of barotrauma had a significant effect on mortality of captured Walleyes. Survival did not significantly differ between deeply hooked fish that had the line cut (11.1%) and those that had the hook removed (22.6%). Results from this study suggest a relatively high incidence of Walleye survival after catch-and-release angling through the ice.
