A crab gauge is one of the easiest ways to ensure your catch meets the legal minimum size requirements. Fisheries and Oceans Canada (DFO) requires recreational harvesters to immediately measure crabs across the widest part of the shell and release any undersized crabs.
The minimum legal size for a Dungeness crab is 165 mm (6½ inches), measured across the widest part of the carapace. Always measure your crab before retaining it and check current DFO regulations for any area-specific restrictions.
The minimum legal size for a Red Rock crab is 115 mm (4½ inches), measured across the widest part of the shell. Undersized crabs must be released immediately.
No. It is illegal to retain female Dungeness, Red Rock, or King crabs in British Columbia. Female crabs must be released immediately after capture.
Measure the crab across the widest part of the shell (carapace), excluding the spines. A properly sized crab gauge makes it quick and easy to verify whether your catch is legal.
Yes. Recreational crabbing in tidal waters requires a valid British Columbia Tidal Waters Sport Fishing Licence. Be sure to review current regulations, daily limits, gear restrictions, and area closures before heading out.
