Blue crabs occur in warm, protected Cape Cod estuaries, but town parking, shellfish and shore-access rules vary. Use Massachusetts’ public-access viewer and the responsible town before choosing a dock or shoreline.
Current Massachusetts blue-crab rules
Blue crab must measure at least 5 inches and the daily limit is 25. Egg-bearing crabs cannot be taken and crabs must be landed whole. Blue-crab trap fishing is prohibited; use actively fished gear such as handlines, dip nets or lawful collapsible gear. No permit is required for blue crabbing unless using SCUBA.
Choose safe water
Avoid wading into tidal channels or strong current. A stable public pier or bank is a safer family setup, but a boat-launch float may prohibit stationary fishing within 50 feet unless signage allows it.
Find current public access
Massachusetts’ Fishing and Boating Access viewer lists ramps, piers and shore-fishing areas. Town restrictions, seasonal parking and shellfish closures still apply.
