We present an ecologically realistic age-structured model specifically tailored to recreational fishing that allows estimating selection differentials on adaptive life-history traits. The model accounts for multiple ecological feedbacks, which result in density-dependent and frequency-dependent selection. We study selection differentials on annual reproductive investment under size-selective exploitation in a highly demanded freshwater recreational fish species, northern pike ([[Esox lucius]] L.). We find that recreational angling mortality exerts positive selection differentials on annual reproductive investment, in agreement wit predictions from life-history theory. The strength of selection increases with the intensity of harvesting. We also fid that selection on reproductive investment can be reduced by implementing simple harvest regulations such as minimum-size limits. The general, yet computationally simple, methods introduced here allow evaluating and comparing selection pressures on adaptive traits in other fish populations and species, and thus have the potential to become a tool for evolutionary impact assessment of harvesting. 2009-08 published Wiley 10.1111/j.1752-4571.2009.00081.x XJ-09-087 Evolutionary Applications; 2(3):335-355 (August 2009) [doi:10.1111/j.1752-4571.2009.00081.x] 1130 1439 66 public Evolutionary Applications 2 3 335-355 TRUE 1752-4563 FALSE info:eu-repo/semantics/article
