Welsh-Spec Shellfish Gauge – 90mm, 100mm, 110mm, 120mm & 130mm Multi-Species Tool

Comprehensive Legal Compliance Checks for Welsh Coastal & Inshore Waters

Navigating Welsh Inshore Fisheries and Conservation Authority (IFCA) bylaws without carrying a cluttered collection of measuring devices is a constant challenge for shore anglers, commercial potters, and boat crews. Carrying mismatched tools risks accidental retention of undersized catch and heavy regulatory fines.

Designed and manufactured in the UK by the original CAD designer, this Welsh-spec multi-species shellfish gauge integrates five key legal landing dimensions into a single compact, heavy-duty frame. Engineered with precise openings covering 90mm through 130mm, it allows for instant, accurate MCRS checks across major Welsh shellfish species right at the water's edge.

Key Marine Engineering Features & Field Benefits

• 5-In-1 Welsh Regulatory Measurement Suite:

  • 90mm Notch: European / Common Lobster (Homarus gammarus) Carapace Limit

  • 100mm Notch: King Scallop Shell Width Limit

  • 110mm Notch: Crawfish / Spiny Lobster (Palinurus elephas) Carapace Limit

  • 120mm Notch: Spider Crab (Maja brachydactyla) Carapace Limit

  • 130mm Notch: Edible / Brown Crab (Cancer pagurus) Width Limit

• Genuine Original CAD Design: As the original designer behind this layout, master models can be modified rapidly for custom millimeter tweaks, personalized slot configurations, or regional requests.

• 100% Saltwater & Weatherproof PETG: Precision 3D-printed using heavy-duty, marine-grade PETG polymer. It will not absorb water, degrade under UV exposure, or snap when dropped on wet rocks or boat decks.

• High-Contrast Molded Markings: Clear, high-visibility digits and millimeter indicators are molded directly into the gauge body, ensuring dimensions remain readable in sea spray, low light, or direct sun.
