Dungeness crab
Fish · Last reviewed 2026-08-23
The large Pacific crab of the North American west coast, and the reason a rod-and-line snare exists at all — it is caught from the surf by casting.
Safety: injury while handling fish — can cause injury needing treatment. One more point applies here.
Contamination and toxins in the catch — Can cause injury needing treatment
Crab viscera on this coast concentrate domoic acid from harmful algal blooms, and health authorities close or restrict the recreational fishery on monitoring results that a person on the beach cannot see. Neither cooking nor the animal's appearance removes the toxin.
What reduces it: Check the current health advisory for the specific stretch of coast before going, not after. Where an advisory restricts consumption to the meat only, the viscera and the cooking liquid are the part it is talking about.
Catching Dungeness crab
What FishingHQ holds on fishing for it. Each entry opens the record behind it.
- Ground
The Dungeness is the crab of the North American Pacific coast, from Alaska down to central California, and it is the animal that makes crab snaring a rod-and-line method rather than a curiosity.
It is a broad, smooth-shelled crab with a serrated front edge and white-tipped claws, living on soft bottoms from the low intertidal down to a few hundred metres, and using estuaries and eelgrass as nursery ground. Males reach around 22 cm across the carapace and females rather less.
What matters to an angler is the ground it lives on. Because it feeds over open sand within casting range of a surf beach, it can be taken with a weighted cage or loop device baited and cast, worked exactly like a fishing rig and retrieved slowly enough that the crab keeps hold. That is a real fishery with its own tackle, not a variant of harbour crabbing with a line.
The rules around it differ sharply over short distances and are the thing to check first rather than last. California's own regulations define the crab loop trap as a gear category; Washington's list of recreational gear is pots, hand and dipnet, and it requires every female to be returned. Neither of those is a fact about the crab. Both are facts about where you are standing.

Crab snaring
California's fisheries regulation defines the crab loop trap as a gear category, and the Dungeness is the animal it is used on: large enough to be worth the cast, and living over the open sand a surf rod can reach.

Identification
No photograph of Dungeness crab has passed identity review yet, so none is shown. FishingHQ publishes a species photograph only once somebody has confirmed the animal in it against the species record’s own diagnostic features.
- Scientific name
- Metacarcinus magister
- Family
- Cancridae
- Water
- Saltwater, Brackish
- Conservation status
- Not assessed
- Regions
- North America
- A broad oval carapace, widest across the middle, with a serrated leading edge of roughly ten teeth either side of the eyes.
- White or pale tips to the claws, which is the quickest separation from the rock crabs on the same ground.
- Purple-brown to light brown above, cream or pale orange beneath.
- Males noticeably larger than females and with a narrow pointed abdominal flap; females carry a broad rounded one.
Size
- Typical
- 0.7–1.2 kg (1.5–2.6 lb)
- Large
- 1.5–2 kg (3.3–4.4 lb)
Exceptional: Reported to about 22 cm carapace width in males and about 16 cm in females; carapace width rather than weight is how this animal is measured and regulated
Lifecycle and reproduction
Epibenthic on soft bottoms from the low intertidal to a few hundred metres, with estuaries, eelgrass and oyster ground used as nursery habitat by juveniles. Commonly five to eight years old, and longer at the northern end of the range.
Larvae are released as plankton and drift for weeks before settling. Mating happens only when the female has just moulted and is soft, which is why a fishery that removes hard-shelled males in season and returns everything else can be managed the way it is.
Feeding and senses
Scavenges and preys on clams, worms, small crustaceans and fish over open sand and mud. Feeding over clean ground within casting range is what makes it reachable from a surf beach.
Finds food by scent carried on moving water rather than by sight, which is why a snare or a net fishes on a tide and does very little in slack, and why the bait matters more than the presentation.
Through the year
Available through the year in parts of the range, but the recreational fisheries are seasonal and structured around shell condition: a freshly moulted crab is soft, poor eating and easily killed by handling, and the season structures exist largely to keep effort off them.
Distribution
North-eastern Pacific: the Aleutian Islands and Alaska south to central California, with records to Magdalena Bay, Mexico. Estuarine and nearshore soft bottoms from the low intertidal to about 360 m.
This is a biological range — where the species occurs, not a prediction that you will catch one. To browse the fishing geography FishingHQ holds, start at fishing places.
Why anglers care
The species that makes rod-and-line crab snaring a method: a weighted loop or cage device is baited, cast into the surf, left for ten or fifteen minutes and retrieved under steady tension so the crab keeps its grip. It is also taken in hoop nets from piers and jetties and in pots from boats. Its significance is that it is a large, genuinely worthwhile crab reachable from a beach with ordinary surfcasting tackle.
Handling and returning
Powerful claws on a heavy animal. Lift from behind, across the rear of the carapace between the back legs, where neither claw reaches. Soft-shelled crabs are easily crushed by a grip that a hard-shelled one would shrug off, and are returned rather than kept in every fishery whose rules were read for this page.

Describe this diagram in words
A crab snare drawn in two states on the same piece of open sand, seen from the side. In the first, the device is soaking: a weighted bait cage sits still on the bottom at the end of a slack mainline, with three monofilament loops standing open above it, held proud so that a crab walking to the bait puts a leg through one. An arrow shows scent carried away from the cage on the run of tide, and a crab is drawn out on the sand walking up the trail towards it. In the second, the device is being retrieved: the mainline is straight and under continuous tension, the cage is travelling along the bottom towards the rod, and the loops have been drawn closed and trail behind it, one of them around a crab's leg. The crab is neither hooked nor holding on — it is tangled, which is why any slack in the line opens the loops again and loses it. Two lines at the foot of the figure state what the drawing cannot: this is surfcasting, with everything that standing on an open beach in the dark involves, and whether a snare may be used at all is a question for the local fisheries authority, because the gear is a defined category in one jurisdiction's rules and absent from a neighbouring one's list.
How this drawing was produced
Drawn in-repository from the standing visual vocabulary. Reviewed for internal consistency: the same weighted cage appears in both panels, the loops radiate from it in the first and trail from it in the second, the mainline is drawn slack in the soaking panel and straight in the retrieve panel, and the crab is approaching in one and held in the other. No loop length, cast distance, soak time or water depth is drawn, because the crab snaring record states none and the regulation the record rests on describes only the number of loops. RENDERED AND LOOKED AT. The retrieve label sat across the seabed line and the crab in the first draft and was moved above the travel arrow.
Safety
Contamination and toxins in the catch is set out at the top of this page, where it cannot be missed.
Injury while handling fish — Can cause injury needing treatment
A crab of this size can break the skin and crush a fingertip. Injuries happen when the animal is picked up from the front, by a claw, or out of a bucket by feel.
What reduces it: Lift from behind across the rear of the shell, look before reaching into a bucket, and use a measure rather than a hand to check size.

Estuary
Juveniles are recorded as inhabiting and foraging in estuaries, particularly over oyster reef and eelgrass, which is a different habitat from the adult fishery and is the reason estuarine closures exist where they do.

Surf beaches
Metacarcinus magister is epibenthic on soft bottoms from the low intertidal down, which puts feeding crabs on the open sand in front of a surf beach. A crab that lived only on reef could not be snared from the shore at all.

Handling fish safely
Crab viscera on this coast concentrate biotoxins from algal blooms, and the fishery is restricted on monitoring results a person on the beach cannot see. Neither cooking nor the animal's appearance removes them, so the advisory has to be checked before going rather than after.
