    dct:description """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.""" ;
