California Department of Fish and Wildlife. Species profiles: life histories and environmental requirements of coastal fishes and invertebrates (Pacific Southwest)-brown rock crab, red rock crab, and yellow crab. California's Living Marine Resources: A Status Report. Rock Crab. Solutions exist for most of these potential effects (e.g., release of bycatch, breakaway lines). No information is available for this particular fishery, but use of baited traps in general may lead to unintended catch, damage to seafloor in rough conditions, and entanglement of marine mammals in buoy lines.Beneficial future management efforts include: increased collaborative data collections, testing effects of a restricted access program in areas of high fishing intensity, gear modifications to reduce bycatch of other species.width at widest part of the body shell) and by including a 3.24 in escape ring on traps. The fishery is sustained by setting a minimum harvest on pre-reproductive crabs (This fishery is one of the only major near shore fisheries with no restricted access and a low capital entry requirement if these factors result in increased fishing pressure (high intensity for long periods of time), reductions in crab abundance and size may result.There is little to no information on the fishery in California.Today, it is illegal to harvest only claws and most are landed alive for sale at fresh fish markets. Prior to 1991, only the trapped crabs’ claws were harvested clawless crabs were returned to the ocean with the hope that claws would regenerate.Most commercial trapping occurs 27-73 m (90-240 ft) deep on open sandy bottoms or nearby rocky reefs.Baited rectangular traps made of welded mesh or collapsible plastic attached to a buoy.As established by the Marine Life Management Act, the California Fish and Game Commission (CFGC) regulates the fishery, and the California Department of Fish and Wildlife (CDFW) manages this fishery in state waters.Adults contribute to the diet of the threatened southern sea otter and other species.

This crab grows in steps, molting the external shell at each step.Though the three species' ranges overlap, red rock crab is most common in northern California, the brown crab in central California and the yellow crab in southern California.Found along California’s coastline, from Baja California to Washington.All three used to be classified under the genus Cancer.The red rock crab is brick red in color, the brown crab is dark brown with red spots, the yellow crab is light brown to pale yellow with no spots.These crabs grow to different sizes, but rarely exceed 20 cm (8”) in width.Males have slender abdomens and are larger than females, which have broad abdomens where they carry eggs.Distinguished by its broad carapaces (outer shell) and claws.
