    dct:description """The dataset collected includes assessment output relating to the years from 
1905 to 2021 inclusive for annual estimates of the following variables for 
each stock: the annual recruitment estimate; the stock size (spawning stock 
biomass); landings (tonnes of fish brought to shore); catches (tonnes of fish 
caught at sea); fishing pressure (a fishing mortality rate); the target 
fishing mortality that will achieve maximum sustainable yield in the long term 
(Fmsy); upper and lower range estimates for Fmsy consistent with multi-annual 
plans and ICES advice; a threshold for spawning stock biomass (MSYB trigger), 
below which fishing mortality should be reduced below Fmsy, following the ICES 
advice rule, to avoid reduced reproductive capacity; a lower limit threshold 
for spawning stock biomass below which there is a high risk of reduced 
reproductive capacity (Blim). The stock assessment data for fish and shellfish 
stocks of UK interest is used to assess indicators of reproductive capacity 
(based on spawning stock biomass) and fishing pressure (based on fishing 
mortality). The applicable location for these data differ by stock, but are 
relevant to UK stock areas in the Celtic Sea / North Sea / wider North East 
Atlantic / Arctic region.""" ;
