Evolutionary consequences of fishing and their implications for salmon pub iis_ecl prog_eep adaptation; fitness; heritability; life history; reaction norm; selection; size-selective mortality; sustainable fisheries We review the evidence for fisheries-induced evolution in anadromous salmonids Salmon are exposed to a variety of fishing gears and intensities as immature or maturing individuals. We evaluate the evidence that fishing is causing evolutionary changes to traits including body size, migration timing and age of maturation, and we discuss the implications for fisheries and conservation. Few studies have fully evaluated the ingredients of fisheries-induced evolution: selection intensity, genetic variability, correlation among traits under selection, and response to selection. Most studies are limited in their ability to separate genetic responses from phenotypic plasticity, and environmental change complicates interpretation. However, strong evidence for selection intensity and for genetic variability in salmon fitness traits indicates that fishing can cause detectable evolution within ten or fewer generations. Evolutionary issues are therefore meaningful considerations in salmon fishery management. Evolutionary biologists have rarely been involved in the development of salmon fishing policy, yet evolutionary biology is relevant to the long-term success of fisheries. Future management might consider fishing policy to (i) allow experimental testing of evolutionary responses to exploitation and (ii) improve the long-term sustainability of the fishery by mitigating unfavorable evolutionary responses to fishing. We provide suggestions for how this might be done. 2008-05 published Wiley 10.1111/j.1752-4571.2008.00020.x XJ-08-027 Evolutionary Applications; 1(2):388-408 (May 2008) (Published online 28 April 2008) [doi:10.1111/j.1752-4571.2008.00020.x] 122 1956 public Evolutionary Applications 1 2 388-408 TRUE 1752-4563 FALSE info:eu-repo/semantics/article
