Physiological response of wild rainbow trout to angling: impact of angling duration, fish size, body condition, and temperature

Abstract: This study evaluated the immediate physiological response of wild rainbow trout to catch-and-release angling in the Alagnak River, southwest Alaska. Information was recorded on individual rainbow trout (n = 415) captured by angling including landing time and the time required to remove hooks (angling duration), the time to anesthetize fish in clove oil and withdraw blood, fish length and weight, and water temperature at capture locations. Plasma cortisol, glucose, ions (sodium, potassium, chloride), and lactat… Show more

“…Descriptive data are reported as mean ± SD. Following previous methods described by Meka and McCormick (2005) and Smit et al (2009) fish were grouped by landing time which was divided into minute intervals (< 1 min, 1-2 min, 2-3 min, etc) and grouped according to the water temperature, i.e. low (<12°C), moderate (16-22°C) and warm (>26°C).…”

“…Clo e oil g.ℓ -1 ) in solution with ethanol (1:9 ratio of clove oil mixed with ethanol) was added to an insulated vessel containing 50 L of fresh river water (Anderson et al 1997;Meka and McCormick, 2005). Following capture, fish were anaesthetised for 2 min in the container, which has been previously shown to have a negligible physiological effect (Wagner et al 2002).…”

“…Anglers should chose optimal equipment matched to the size of fish that are expected to be encountered. There is substantial evidence supporting the notion that the size of fish is positively correlated with the duration of the angling event (Thorstad et al, 2003;Meka and McCormick, 2005). Efforts to intentionally prolong the angling event through the use of light line or rods should be dissuaded as this would not be consistent with the notion of improving animal welfare.…”
