The assessment of environmental status for commercially exploited non-quota shellfish stocks is based on the results from national stock assessments for shellfish that are mostly data-limited. Although methods for stock assessments might vary between stocks and depend on the quantity and quality of the available data, the relevant stock assessments data are considered equally following the method for GES in the fishing pressure indicator assessment. This assessment product consider national stock assessments that estimate biomass and reference points to establish a harvest rate or fishing pressure that can sustain the maximum sustainable yield for 62 non-quota shellfish stocks from 1990 to 2019 (Dobby and others 2012, 2017; Delargy and others 2019; Cefas 2015a, 2025b, 2020a, 2020b; Lawler and others, 2023; Mesquita and others 2016, 2017, 2023).
