Fisheries induced evolution
Did you know?
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 … WebDec 1, 2007 · Fisheries-induced evolution was found to be not only possible but also likely under realistic rates of exploitation and size selectivity of fisheries 9, 26, 52.

WebMar 7, 2012 · From a fisheries perspective, the impacts of fisheries-induced evolution are generally considered negative owing to a lower biomass yield and reduced catches [8,9,13]. From a conservation … WebFisheries-induced evolution research has also identified or inferred negative implications to population recovery and sustainable yield, prompting calls for evolutionarily enlightened management to reduce the probability of FIE and mitigate its risks. Sufficient time has now elapsed to evaluate whether predicted negative consequences to ...
