27 September 2024: First posting of updated MSE Explorer, using results for MSAB020.

In the grids below, the light blue colored cells indicate the Management Procedures that have simulations available for evaluation in this tool. Dark blue cells indicate the Management Procedures that are currently chosen for evaluation and comparison. Dark blue shows MPs selected

Download Table

This table shows MSE priority performance metrics (and the probability that the long-term/short-term spawning biomass is greater than the 2023 estimated spawning biomass) for alternatives defined by the stock assessment tactical decision table. There are number of differences between this HSP table and the stock assessment tactical decision table.

1) These MSE projections use the median SPR from the decision table as the fixed input SPR, while the decision table uses a fixed mortality for all years.

2) These MSE projections use a 4-area operating model tuned to the 2022 stock assessment using data through 2022.

3) These MSE projections incorporate additional uncertainties, as compared to the stock assessment, to quantify potential long-term outcomes.

4) The MSE projections are intended to compare long-term outcomes of different management procedures, rather than predict a specific TCEY or biomass.

A method to use this tool is to select a small set of management procedures (MPs) from the elements on the left. Then compare these MPs using plots or the table. The plots show the general trends across SPR values for the control rule and constraint elements. The table provides specific numbers.

The table with the selected elements may be downloaded to a csv file. It is easy to then open this in Excel for further comparison, formatting, and plotting. The plots may be saved by right-clicking on the plot and choosing 'Save image as'.
