population

An implementation of equilibrium-based yield per recruit
methods. Yield per recruit methods can used to estimate the optimal
yield for a fish population as described by Walters and Martell (2004)
<isbn:0-691-11544-3>. The yield can be based on the number of fish
caught (or harvested) or biomass caught for all fish or just large
(trophy) individuals.
