This paper summarizes progress on the development of Operating Models (OMs) for IOTC yellowfin (YFT) tuna. MP evaluation updates for yellowfin and bigeye tunas are described in Kolody and Jumppanen (2018a). This paper builds on the work presented and reviewed at the IOTC informal MSE Working Group in March 2018 (Kolody and Jumppanen 2018d,e).
The latest version of the MSE software is publicly available from github, with a recently updated technical description and user manual (https://github.com/pjumppanen/niMSE-IO-BET-YFT/).The BET and YFT MSE projection software has undergone several changes in the past year, with a substantial rewrite to improve memory usage and parallel processing, which greatly improves MP evaluation speed. Most of these changes to the computational engine are not visible to the end user.
