Although no formal MSE has been mandated for southern swordfish, the SCRS has acknowledged its potential utility and continues to evaluate stock status and management options.

 

Progress

The South Atlantic swordfish closed-loop simulations began with a minimalist framework described in Taylor et al. (2022), which used multivariate life-history priors and CPUE clustering to develop four operating models (OMs) and test 42 Candidate Management Procedures (CMPs) using satisficing criteria. This work was expanded in Taylor (2023), which introduced hierarchical clustering of CPUE series, refined the OM structure, and incorporated visual inspection filters to improve CMP screening. The most recent update, Taylor (2024), consolidates these methods, identifies 14 high-performing CMPs across OMs, and outlines next steps, including CMP tuning, incorporation of data lags, and enhanced performance evaluation.
