Data Description
Summary of the most recent stock assessment results for each assessed HMS species.
Introduction to Indicator (Please explain your indicator)
This section summarizes Highly Migratory Species Stock Status as it is presented in the latest Atlantic Highly Migratory Species Stock Assessment and Fishery Evaluation (SAFE) report. Stock assessments for Atlantic HMS are completed through one of three processes. Most Atlantic HMS stocks that are managed internationally under the authority of the MSA and ATCA (tunas, billfish, and swordfish) are assessed by the ICCAT SCRS. Given their migratory nature and because of their interactions with ICCAT fisheries, some pelagic sharks are also assessed by the ICCAT SCRS. Other shark stocks that do not interact with ICCAT fisheries are assessed via the SouthEast Data Assessment and Review (SEDAR) process. SEDAR assessments are completed for domestically managed HMS shark stocks. Sharks may also be assessed through an independent stock assessment is completed by a third party and approved for use in management by NOAA Fisheries (“external assessments”). Unless otherwise indicated, most assessments presented herein are done through either the ICCAT or SEDAR process.
Key Results and Visualization
The domestic and international status of 28 species or stocks are described in the most recent HMS SAFE report. International and domestic HMS stock status may not be identical, based on different thresholds and status determination criteria used at the domestic and international levels (see Figures).
Regarding international stock status, overfishing is either not likely to be occurring or not occurring for 3 and 7 species/stocks, respectively. Overfishing is occurring for 3 species/stocks, and is undetermined for 1 stock. Regarding domestic stock status, overfishing is not occurring for 18 species/stocks. Overfishing is occurring for 5 species/stocks, and is unknown for 4 species/stocks
Regarding international stock status, 2 species/stocks are likely not overfished, 4 species/stocks are not overfished, and 6 species/stocks are considered overfished. Regarding domestic stock status, 13 species/stocks are not considered overfished (2 of these are either rebuilding or are rebuilt), 9 species/stocks are considered overfished, and 5 species/stocks are considered unknown.
Implications
TBD – our assessment team has asked that the Kobe plots be redone, so please do not include them here yet.
Spatial Scale
Species-specific; depends on the extent of the managed stock. Can be regional (e.g., Gulf of Mexico or Atlantic blacktip shark) or could be basin-wide (e.g., North Atlantic swordfish, Western Atlantic bluefin)

Define Variables
Current Relative Biomass level = finalized biomass estimate provided in latest stock assessments
Bmsy = biomass at maximum sustainable yield
Threshold = the threshold identified in respective assessments to indicate overfished vs. overfishing
International Stock Status, Domestic Stock Status, Years to Rebuild = estimate if provided in assessments
Rebuilding Start Date (End Date) = estimate if provided in assessments.
Current Relative Fishing Mortality Rate = finalized mortality rates provided in latest stock assessment
Maximum Fishing Mortality Threshold = reference point identified in latest stock assessment
International Stock Status, Domestic Stock Status.
Stock = the name of the stock assessed
Last Assessment Year = the year in which the latest assessment was finalized
Upcoming Assessment = Year that the next assessment is anticipated (if scheduled)
Notes = additional information.
Shark Stock = the name of the stock assessed
Last Assessment Year = the year the latest assessment was finalized
Last Assessment Type = unless otherwise indicated, this identifies the type of SEDAR assessment used (typically “Benchmark”, “Standard”, or “Update”). This is subject to change as SEDAR adjusts their assessment types.
Upcoming Assessment = year of upcoming assessment, if scheduled.
Upcoming Assessment Type = unless otherwise indicated this identifies the type of SEDAR assessment used.
Notes = Relevant information concerning the domestic assessments.
