Figures

Figure 1. Comparison of turbot and brill Operating Models.

Figure 2. Comparison of turbot and brill Operating Models for 1 iteration, note that recruitment deviates are the same across iterations.

Figure 3. Comparison of turbot and brill stock recruitment relationships.

Figure 4. Comparison of turbot and brill production functions.

Figure 5. Cross correlation between SSB and recruitment, i.e. brill is driven by recruitment from 1 to 2 years and turbot by 4 years previously.

Figure 6. Cross correlation between F and length, i.e. brill length is driven by current F and turbot by 4-5 years previously.

This vignette and many of the methods documented in it were developed under the MyDas project funded by the Irish exchequer and EMFF 2014-2020. The overall aim of MyDas is to develop and test a range of assessment models and methods to establish Maximum Sustainable Yield (MSY) reference points (or proxy MSY reference points) across the spectrum of data-limited stocks.
