Sardine Stock-Recruit Relationships

This brief document shows the difference in the range of the stock-recruitment relationships between the Operating Model (OM) used to develop OMP-14 and those to be used to develop OMP-17. The relationships are, however, not directly comparable as spawner biomass is not directly comparable between the two OMs. Sardine spawner biomass was defined as 2+ biomass in the OMs used to develop OMP-14, while the new OMs use maturity-at-length.
