Does boldness explain vulnerability to angling in Eurasian perch Perca fluviatilis?
Consistent individual differences (CIDs) in behavior are of interest to both basic and applied research, because any selection acting on them could induce evolution of animal behavior. It has been suggested that CIDs in the behavior of fish might explain individual differences in vulnerability to fishing. If so, fishing could impose selection on fish behavior. In this study, we assessed boldnes...
متن کاملBalancing past and present: how experience influences boldness over time in Eurasian perch
Adapting to fluctuating predation conditions is a challenge for prey. By learning through experience, animals may adjust their anti-predator behavior to better reflect current predation risk. Although many studies show experience of predation to alter prey behavior, little is known about how prey rely on such experience over time. By comparing boldness over different temporal scales between ind...
متن کاملToward a mechanistic understanding of vulnerability to hook‐and‐line fishing: Boldness as the basic target of angling‐induced selection
In passively operated fishing gear, boldness-related behaviors should fundamentally affect the vulnerability of individual fish and thus be under fisheries selection. To test this hypothesis, we used juvenile common-garden reared carp (Cyprinus carpio) within a narrow size range to investigate the mechanistic basis of behavioral selection caused by angling. We focused on one key personality tra...
متن کاملLife-history traits and energetic status in relation to vulnerability to angling in an experimentally selected teleost fish
In recreational fisheries, a correlation has been established between fishing-induced selection pressures and the metabolic traits of individual fish. This study used a population of largemouth bass (Micropterus salmoides) with lines of low vulnerability fish (LVF) and high vulnerability fish (HVF) that were previously established through artificial truncation selection experiments. The main ob...
متن کاملLife-history Variation and Age at Maturity in Eurasian Perch (Perca fluviatilis L.)
Heibo, E. 2003. Life-history variation and age at maturity in Eurasian Perch (Perca fluviatilis L.) This thesis deals with life-history variation in perch, with special focus on age at maturity. We conducted field studies to uncover the variation within short geographic distances and a literature review to study variation on a large geographic scale in order to reveal some factors affecting lif...
