This study aimed to quantify the impact of prolonged exposure to a retained lure (simulated break off in recreational angling) to the physiology and behaviour of northern pike (Esox lucius) was studied in a laboratory setting. We found that the retention of a lure did not significantly affect metabolic rate, blood physiology or locomotor activity of pike. However, gill ventilation rate was found to be elevated in pike hooked deeply in the throat suggesting that lures in obstructive locations may somewhat challenge recovery from exercise.
We examined the physiological and behavioural consequences of, and recovery from, catch-and-release related stressors using a combined laboratory and field study in northern pike (Esox lucius L.). Our results emphasize that angling-induced stressors result in physiological and behavioural disturbances, but that recovery is quick. This suggests that pike are relatively resilient to catch-and-release related stressors but air exposure durations should be kept <300 s to minimize behavioural impairment.
We show for catch and release angling for northern pike (Esox lucius) in the Baltic Sea that hooking location and size of fish captured vary among lure types. Our results supported the notion that anglers can minimize injury in northern pike angling by the choice of appropriate gear. In addition, our study is one of the first to show that hooking location is also affected by water temperature; low temperatures tended to result in deeper hooking.
