WebDec 3, 2012 · Fisheries-induced evolution and its impact on the productivity of exploited fish stocks remains a highly contested research topic in applied fish evolution and fisheries science. Although many quantitative models assume that larger, more fecund fish are preferentially removed by fishing, there is no empirical evidence describing the ... 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
