Conditioning results for the 2022 Hake Reference Set Operating Models for OMP testing
Results are presented for the conditioning of the 2022 hake Reference Set (RS) of Operating Models (OMs) to be used in testing OMP-2022. Contrary to the 2018 RS, all models estimate both species to be above 𝐵𝑀𝑆𝑌. Some of the estimates of the survey catchability coefficients are unrealistically high, but this is most likely a consequence of trade-offs between fitting to different types of data, rather than simply biologically unrealistic results. The Ricker models appear to have multi-modal likelihood surfaces with “switching” between the M. capensis stock recruitment parameters, but in all cases estimates of abundance remain above 𝐵𝑀𝑆𝑌.
