25.1 Introduction to Indicator

There is interest in the stock status of predators and commercially or recreationally valuable Highly Migratory Species. The latest Highly Migratory Species Stock Assessment and Fishery Evaluation (SAFE) report provides a summary of stock assessment information and current stock statuses of HMS under domestic and applicable international stock thresholds. Some stocks use proxies for biomass, such as spawning stock biomass (e.g., bluefin and northern albacore tunas) and spawning stock fecundity or number of fish (e.g., sharks).

25.2 Key Results and Visualizations

TBD – we have a meeting in mid-November to finalize decisions regarding this contribution. The most complete representation of these data can be found in our SAFE report (starting on pg 31, Table 2.1 – Table 2.4)

25.7 Accessibility and Constraints

All stock assessment results are publicly available (see Data Sources). Summarized Atlantic HMS data are available in the Atlantic HMS SAFE Reports. Species with a range of uncertainty estimates for F/Fmsy and B/Bmsy and assessments completed very recently may not be included in Stock Smart queries.
