UK Non-Quota Shellfish Stock Status Assessments from 1990 to 2019

62 non-quota shellfish stocks are assessed for Good Environmental Status based on national stock assessments from 1990 to 2019. The dataset, managed by the Marine Environmental Data & Information Network, aggregates results from multiple scientific reports and assessments. It supports the UK Marine Strategy's evaluation of fishing pressure and sustainable yield for commercially exploited shellfish.

Use Cases

• Modeling maximum sustainable yield (MSY) based on estimated biomass and reference points mentioned in the description.
• Assessing trends in fishing pressure and stock health over the 1990-2019 time period.
• Evaluating the environmental status of specific shellfish species under descriptor 3 of the UK Marine Strategy.
• Comparing assessment methodologies and data quality across different data-limited shellfish stocks.

Strengths

• Covers 62 distinct non-quota shellfish stocks.
• Provides a 30-year time series from 1990 to 2019.
• Aggregates results from multiple published national stock assessments and scientific reports.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
