Incorporation of a model of krill recruitment into the Butterworth et al. Stochastic krill dynamics model (SKDM)

The method of simulating recruitment variability using observed ratios of 0 year krill to the total population is validated and tested. The method also links natural mortality to krill recruitment. Incorporation into the SKDM increases the variability of the krill population dynamics predicted by the model, although median escapement is similar to the previous formulation of the model.
