About Red Rock Crab

Cancer productus, one of several species known as red rock crabs, is a crab of the genus Cancer found on the western coast of North America. This species is commonly nicknamed the Pearl of the Pacific Northwest.

Appearance

Cancer productus has carapace teeth that are somewhat broad and rounded with teeth between the eyes of nearly equal size and shape. The carapace of C. productus is widest at the posterior-most tooth, up to 20.0 cm wide. The pincers are large with distinctive black tips. This species lacks serrations or projections on the ventral side of the claws. Adults have a brick-red coloration throughout. The coloration of juveniles is diverse, often white, sometimes with red spots, or zebra-striped.

Habitat

Cancer productus ranges from Kodiak Island, Alaska, to Isla San Martine, Baja California. It inhabits mid-intertidal waters to 79 m depth.

Humans & conservation

Cancer productus is harvested by sport and commercial fishermen in California, mostly from Morro Bay south. The California rock crab fishery is made up of three species – the yellow rock crab (C. anthonyi), the brown rock crab (R. antennarium), and the red rock crab (C. productus). Rock crab landings for 1999 were 790,000 pounds and have averaged 1.2 million pounds per year from 1991–1999.

It is not as sought after as Dungeness crab due to the considerably lower amount of flesh. However, the flesh has a delicate flavor and slightly sweet taste. The similar Cancer pagurus has a major commercial fishery in western Europe. Both males and females with a carapace exceeding 5 inches (130 mm) may be harvested in Washington state, when in season .
