WebApr 4, 2008 · As exemplified in the fisheries-induced-evolution literature, the effects of harvesting stressors at the population scale can also emerge at the physiological and individual scale on life history... 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 ).

http://www.shaunkillen.com/fisheries-induced-evolution 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 … See more Fishing practices that permanently remove animals from their population (i.e. not catch and release) drive direct fisheries-induced evolution by removing the genetic materials of those animals from the population. … See more Outside of observational data collected from active fisheries, the evidence for fisheries-induced evolution, or its symptoms, may be … See more Fisheries-induced evolution is a function of the fishing-induced genetic drift, and to some extent represent the reduction of genetic diversity … See more
