International (ICES) and national (UK) fish stock and shellfish stock data from 2021 assessment year
Summary
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.

Lineage
These stock assessment data are updated from a version released in 2021. Stock assessment data from ICES form the core of this dataset. The data sets for internationally assessed stocks were collected from the ICES stock assessments advice sheets of each stock and year. The data sources can be found at the ICES website (`http://standardgraphs.ices.dk/stockList.aspx`_) when selecting the relevant stock and year. Data stating FMSY ranges originate from the ICES advice sheets. The datasets for the UK national shellfish stocks data originate from the following specific datasets and associated reports: Cefas 2020 Lobster (*Homarus gammarus*) Stock Status Report. 18pp. Available online at `https://www.gov.uk/government/publications/crab-and-lobster-stock-assessments-2019`_ Cefas 2020 Edible crab (*Cancer pagurus*) Stock Status Report.
