Abstract
Parameters for a simple stage-structured harvesting model are derived for five North Sea demersal fish stocks. The parameters are used to generate contour plots of fitness and yield on axes of size-at-maturity Vs size-at-first-capture, and age-at-maturity Vs age-at-first-capture. Such graphs are used qualitatively to assess possible changes in the exploited populations that might result from management actions such as altering mesh size (and hence size-at-capture) and/or harvesting rate.
