Stock assessment data sets for 58 quota fish stocks from 2003 to 2021 
inclusive in the Celtic Seas and Greater North Sea and widely distributed were 
collected from ICES international stock assessments database (ICES Stock 
Information Database [year accessed 2023] ICES, Copenhagen, Denmark. 
https://sid.ices.dk_). Stock assessment data sets for 62 non-quota 
shellfish stocks from 1990 to 2019 inclusive in the Celtic Seas and Greater 
North Sea were collected from national stock assessments reports and 
publications.
The stock assessment data for fish and shellfish stocks of UK interest is used 
to assess Good Environmental status for commercially exploited fish and 
shellfish, descriptor 3 (Impact of fishing on target species) under the UK 
Marine Strategy (UKMS). The 2024 UKMS assessment uses a stock assessment data 
to calculate of percentage of stocks being within safe biological limits 
considering 6-year period where required data is available to integrate two 
indicators assessments, reproductive capacity (based on spawning stock 
biomass) and fishing pressure (based on fishing mortality), considering 
specific maximum sustainable yield reference points that are relevant for each 
stock.
