WebResults Rates of fisheries‐induced phenotypic change. There was considerable variation in the rates of evolutionary change reported in modelling studies; for example, for F values ranging from 0.5 to 1.0 per year, rates of evolution varied from 0.02% to 0.93% per year, with the mean of 0.25% per year (Fig. 1).Similarly, for the same magnitude of fishing … Webfisheries, an understanding of the various factors that influence stock productivity and dynamics is necessary.
