Description:
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.
