WebJul 1, 2013 · Fisheries-induced evolution is one mechanism that can alter population characteristics, leading to “shifting” reference points by modifying the underlying biological processes or by changing the perception of a fishery system.

WebJul 1, 2010 · Evidence for fisheries-induced evolution (FIE) has been reported in a number of different species (see reviews in Jørgensen et al., 2007, Kuparinen and Merila, 2007). The main problem in the study of FIE is to disentangle genetic changes from the phenotypic plasticity in traits values ( Rijnsdorp, 1993a , Law, 2000 , Heino et al., 2002a ). WebI focus on fisheries-induced evolution, life-history strategies, and migration behaviour especially in salmonid fishes using long term data. …

Fisheries-induced evolution (FIE) is the microevolution of an exploited aquatic organism's population, brought on through the artificial selection for biological traits by fishing practices (fishing techniques and fisheries management). Fishing, of any severity or effort, will impose an additional layer of mortality to the natural population equilibrium and will be selective to certain genetic traits …
