Razor Clam: Welfare in Emerging UK Aquaculture

Key Welfare Facts

Razor clams are commercially valuable bivalves being developed as aquaculture species in Scotland and Ireland.
Wild harvest using pressurised salt injection to trigger emergence has significant bycatch and habitat disturbance issues.
Aquaculture trial systems face challenges retaining burrowing species in containment systems without stress.
Sentience evidence for razor clams as bivalves is limited but emerging research on bivalve nociception is relevant.
Tidal fluctuation management in intertidal cultivation plots affects desiccation stress in juvenile and adult clams.
Disease challenge including Vibrio bacteria is a significant welfare and mortality risk in hatchery-reared juveniles.

Welfare Assessment

Razor clam aquaculture welfare is an emerging field requiring precautionary standards as the industry develops. Supporting research into appropriate cultivation systems and applying best-practice bivalve handling reduces potential welfare impact during the industry's development phase.
