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. For example, food availability, temperature, population density, and size structure can impact the growth rates of individual fish, thereby influencing vulnerability to ... 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 …

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).
