Abstract
We show how simple stage- and size-structured models may be used to assess the possible evolutionary consequences of size-selective harvesting regimes. Clonal models are used, and invasibility techniques are applied to show that equilibrium adult biomass is the key quantity and to derive a straightforward fitness measure, R. For a population with an ESS in the character(s) of interest (life-history traits) prior to harvesting, it is possible to use R, and the equilibrium biomass yield per unit time, Y, to explore possible outcomes of harvesting strategies.
