Behavioural and metabolic consequences after a single generation of angling selection in brown trout

摘要: Abstract The behavior of organisms can affect their vulnerability to human induced selection, including recreational angling. Angling is expected select fish with bold behavior, which may be linked low stress responses through coping styles. Brown trout (Salmo trutta) an intensively fished salmonid, and thus provides a relevant model study artificial human-induced selection by We used experiment possessing high or angling understand the consequences on traits related styles metabolic rate. produced lines in two populations brown –one wild one reared captivity for several generations- offspring common garden conditions. then assessed minimum average rates, boldness sensitivity juveniles at age 1 year. had population-specific effects risk taking-related latency exploration tendency, differed measured traits, could due combination genetic non-genetic effects. Our evidence personality suggests that rate might also affected. results explained contrasting frequencies proactive reactive style populations. Significance statement Hunting fishing humans, as any predation, individuals behaviors, potentially leads increase shyness prey Because this occur many stocks, we experimentally tested offspring. different hatchery population trout, making from parents more willing take risks have faster metabolism than highly vulnerable parents, but having only weak effect population. implies lead accumulating behavioral, change over time.
