Summary

Between 2021 and 2025 Cefas conducted a pilot study to investigate which common whelk (Buccinum undatum) metrics may be informative to collect for English waters stock delineation purposes, and at what spatial resolution. These metrics primarily include shell length distributions and associated sampling metrics (haul coordinates, gear type, pot soak times). Select samples were sent to Bangor University for dissections, providing further biometrics including; shell dimensions (length, width, aperture), weights (whole animal, gonad, foot), sex, maturity, estimated ages. Mark-Recapture Surveys were conducted in 2022 and 2024 in The Wash where tag numbers, positional/temporal data for release/recapture, and environmental parameters (sea depth and temperature) were recorded alongside shell length distributions.
