WebNov 23, 2007 · Fisheries-induced evolution is likely to diminish yield and degrade ecological services within decades, having an impact on species, ecosystems, and societies. Evolutionary effects could magnify the ecological challenges that already threaten sustainable harvesting. Webfisheries, an understanding of the various factors that influence stock productivity and dynamics is necessary. One such factor that has received considerable scientific attention in recent years is fisheries-induced evolution (FIE).
