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 ... WebJul 8, 2013 · Therefore, fisheries-induced evolution (FIE) may reduce yield (2, 4, 12, 13) and may even imply a “Darwinian debt” to be paid back by future generations, at least if …

WebApr 21, 2024 · Laboratory experiments have demonstrated rapid fisheries-induced evolution causing widespread impacts across the fish genome (4, 5), and many wild populations of fish today indeed mature at earlier ages and at smaller sizes compared to decades ago . Putting lab and field data together, however, has been a major challenge.
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].
