This table provides metadata for the actual indicator available from UK statistics closest to the corresponding global SDG indicator. Please note that even when the global SDG indicator is fully available from UK statistics, this table should be consulted for information on national methodology and other UK-specific metadata information.
Percentage of marine fish (quota) stocks of UK interest; A) harvested sustainably; B) with biomass at levels that maintain full reproductive capacity
The indicator comprises of two measures – the percentage of fish stocks in seas around the UK that are harvested sustainably; and those at full reproductive capacity. It is based on a group of 20 species in 57 stocks for which there are reliable estimates of fishing mortality and spawning biomass, together with MSY reference points for fishing mortality and biomass that allow the sustainability of the stocks to be evaluated. The indicator stocks include a range of local and widely distributed species of major importance to the UK fishing industry. The measures are assessed as follows – A) an evaluation of the temporal trends in the exploitation level of stocks of UK interest with respect to the fishing mortality target FMSY. The aim is to increase the proportion of stocks fished at or below FMSY and reduce to zero the number of stocks of unknown status relative to FMSY. B) an evaluation of the temporal trends in the spawning stock biomass (SSB) of stocks of UK interest with respect to safe biological limits. The aim is to increase the proportion of stocks with SSB at or above MSY Btrigger and reduce to zero the number of stocks that have unknown status relative to MSY reference points.
|Unit of measurement||
The indicator comprises two measures assessed separately - A) the percentage of stocks fished at or below the level capable of producing Maximum Sustainable Yield (FMSY); and B) the percentage of stocks with biomass above the level capable of producing Maximum Sustainable Yield (MSY Btrigger).
Data follows the UN specification for this indicator. This indicator has been identified in collaboration with topic experts.
