Greenland Halibut MSE Results for Updated SCAA Reference Case and Robustness Test Operating Models
This paper reports the results of the application of 18 potential Management Procedures (MPs) to the Base Case and seven robustness test operating models based on SCAA assessments of the Greenland halibut resource. One of these MPs is selected as a preferred candidate (subject to its performance for...

This paper reports the results of the application of 18 potential Management Procedures (MPs) to the Base Case and seven robustness test operating models based on SCAA assessments of the Greenland halibut resource. One of these MPs is selected as a preferred candidate (subject to its performance for XSA‐based operating models) on the basis of satisfying virtually all performance targets identified at the May NAFO WGMSE meeting and achieving relatively high catches. The one drawback for this MP (and also all others considered) is failure to meet the specified resource recovery target under robustness test SCAA5 (a lower stock-recruitment steepness), and suggestions are made in that regard. Suggestions are also made in relation to “exceptional circumstances” provisions where over‐riding the TAC recommendation output by the MP becomes scientifically justified, and for catering for possible future TAC over‐runs. Following discussions of these analyses with our EU principals, results for four further variants of these MPs have been added for consideration. |
