calc_recruitment

Calculate recruitment from stock-recruit function

Implementation of a next-generation, multi-stock age-structured fisheries assessment model.
'multiSA' is intended for use in mixed fisheries where stock composition can not be readily identified in
fishery data alone, e.g., from catch and age/length composition. Models can be fitted to genetic data,
e.g., stock composition of catches and close-kin pairs, with seasonal stock availability and movement.
