Cefas conducted a pilot study between 2021 and 2025 to investigate informative metrics for common whelk stock delineation in English waters. The data includes shell length distributions, sampling metrics like haul coordinates and gear type, and biometrics from dissections such as shell dimensions, weights, sex, and maturity. Mark-recapture surveys in 2022 and 2024 provide tag numbers, release/recapture data, and environmental parameters like sea depth and temperature.
Use Cases
- Modeling whelk population growth and stock delineation based on shell length distributions and biometrics.
- Analyzing spatial patterns in whelk metrics using haul coordinate data.
- Studying animal movement and survival rates using mark-recapture tag and recapture data.
- Investigating relationships between environmental parameters like sea temperature and whelk biology.
Strengths
- Data collection spanned a multi-year pilot study from 2021 to 2025.
- Includes multiple data types: field sampling metrics, laboratory biometrics, and mark-recapture surveys.
- Specific geographic focus on The Wash provides a defined study area.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Data may reflect geographic/temporal bias inherent to the pilot study in The Wash.
