Summary description of the results

Full description and interpretation of the results for the MSE can be found in the final report via the Council’s Recreational Summer Flounder MSE webpage.
Operating Models: simulations were conducted for three operating models, a base-case ( Base), a MRIP Bias scenario that conditioned the operating model assuming the MRIP estimates of recreational catch are biased high, and a distribution shift ( Shift) model that modeled a northward shift over time in the avaialbility of summer flounder to the recreational fishery.
The performance of seven Management Procedures was evaluated, which differed in the regulations settings for the recreational fishery. A summary description of the Management Procedures, and the explanation of the notation used in the plots below can be found in this table.
Each Management Procedure was applied to each operating model and compared using 17 Performance Metrics summarizing performance associated with four Management Objectives. 100 simulations were conducted for each combination of Operating Model and Management Procedure. Details of management objectives and the performance metrics, including the notation used in the plots below can be found in this table (scroll to page 2).
