Jersey-Spec Shellfish Gauge – Lobster, Brown Crab, Spider Crab, Scallop & Ormer

Comprehensive 5-Species Compliance Checks for Jersey & Channel Islands Waters

Staying compliant with specific Channel Islands fishery bylaws without carrying multiple bulky measuring devices can be a constant challenge for shore gatherers, divers, and commercial boat crews. Missing or mismatched tools risk accidental retention of undersized catch and severe regional penalties.

Designed and manufactured in the UK by the original CAD designer, this Jersey-spec multi-species shellfish gauge combines five essential legal landing measurements into a single, lightweight tool. Engineered with precise openings for Jersey’s regulatory limits, it allows for fast, accurate size verification right at the water's edge.
