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. 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
