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 … 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 … city continental hotel https://kwasienterpriseinc.com
