This table provides metadata for the actual indicator available from US statistics closest to the corresponding global SDG indicator. Please note that even when the global SDG indicator is fully available from US statistics, this table should be consulted for information on national methodology and other US-specific metadata information.
|Actual indicator available
|The Fish Stock Sustainability Index (FSSI)
|Actual indicator available - description
|The FSSI measures the performance of the most important federally-managed stocks that represent 85% of total U.S. catch.
|Date of national source publication
|Method of computation
|Scheduled update by national source
|U.S. method of computation
|Stocks are at the sustainable level if abundance ≥ 80% of the abundance at the maximum sustainable yield, with the exception of rebuilding stocks, which must be at 100%. Percentage of stocks at sustainable level is calculated by dividing the total number of stocks at the sustainable level by the total number of FSSI stocks with known stock status / abundance levels.
|Comments and limitations
|1) The global metadata indicates that fish stocks are within biologically sustainable levels if abundance is at or higher than the level that can produce the maximum sustainable yield (MSY). All U.S. federal stocks are managed to achieve the sustainability goals of the Magnuson-Stevenson Act, including requirements to end overfishing and rebuild, to achieve MSY. In 2015, 91% of federally managed stocks were not subject to overfishing and 84% were not overfished. U.S. Metadata indicates that fish stocks are within biologically sustainable levels if abundance is at or higher than 80% for non-rebuilding stocks (100% for rebuilding stocks) of the level that can produce maximum sustainable yield. 2) The Global Metadata reports at the United Nations statistical areas by species or species groups, while U.S. Metadata reports at the species complex, species, or stock level for U.S. managed stocks throughout their range. Note: US data are not available for years prior to 2005.
