📖 1,346 words6/29/2026

Direct Answer

For the 2025–2027 crabbing season on the Potomac River, the Maryland Department of Natural Resources and the Potomac River Fisheries Commission enforce a minimum shell width of 5 inches for hard-shell male blue crabs, with a daily creel limit of 1 bushel per person (approximately 6–7 dozen crabs) and no more than 2 bushels per vessel. No female crabs may be kept from March 1 through June 15, and after June 15, a maximum of 10 female crabs per person per day is allowed, with a minimum shell width of 5¼ inches for females. Crab pots must have cull rings (minimum 2⅜-inch diameter) and escape vents (minimum 2×6 inches), and troylines are limited to 300 hooks per line. All recreational crabbers must hold a valid Maryland tidal fish license ($15 for residents, $30 for non-residents) and comply with Potomac River-specific closures: no crabbing within 100 feet of any marina fuel dock, and no pot crabbing within 50 feet of a marked channel. Commercial crabbing requires a separate PRFC license with 200-pot maximum and seasonal limits (March 17–November 30 for hard crabs, with a 15-bushel daily cap).
