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 … WebJan 30, 2013 · The theory of fisheries-induced evolution can be traced back to 1981, when the Canadian fisheries scientist William Ricker suggested that coho salmon (Oncorhynchus kisutch) and pink salmon ... fishing boat rental lake powellWebSep 30, 2024 · Fishing can impact a variety of physiological and life-history traits, often in non-random directions, through fisheries-induced evolution [3,4].
