WebSep 30, 2024 · Additionally, traits altered by fisheries-induced evolution may be maladaptive in a natural system once fishing is removed (i.e. small groups will be poor at avoiding their natural predators, assuming the predators return following a decrease in fishing). Therefore, even if fishing is removed, these populations may be at risk of further ... WebMuch of the concern about fisheries-induced evolution relates to impaired recovery even if fishery mortality is reduced (12, 45, 46). Loss of alleles during a selective sweep, for example, might lock a population for an extended period of time in a state of low biomass and maturation at young ages and small sizes.

WebSep 15, 2009 · Additionally, it is well known that fishing can induce the evolution of traits such as size and age at maturity in the target species, but also induce larger, ecosystem level changes, some of ... 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 …

WebAug 1, 2024 · Various factors determine which fish are vulnerable to capture and therefore could have an effect on the likelihood, direction, or detectability of fisheries-induced evolution.

WebAug 1, 2024 · Scientists have long suspected that rapid evolutionary change in fish is caused by intense harvest pressure. Now, for the first time, scientists have unraveled genomic changes that prompt fisheries-induced evolution – changes that previously had been invisible to researchers, according to a study published in Science, Aug. 2.

WebJul 1, 2010 · Evidence for fisheries-induced evolution (FIE) has been reported in a number of different species (see reviews in Jørgensen et al., 2007, Kuparinen and Merila, 2007). The main problem in the study of FIE is to disentangle genetic changes from the phenotypic plasticity in traits values ( Rijnsdorp, 1993a , Law, 2000 , Heino et al., 2002a ).
