Scarlet King Crab
Scarlet King Crab forms pods, piles of 1000s of individuals that can be several feet high, this behavior is thought to be defense against predators.
- Amongst king crab species, the scarlett king crab is comparatively smaller. 
- Has a bright red, or scarlet, carapace.
- Ranges from 3.6-9.07 kg (8-20 lbs) in weight. 
- Found from the Bering Sea, Gulf of Alaska, southward along the eastern Pacific slope to San Diego. 
- Although not much is known about the scarlet king crab, other king crab species can survive 20 to 30 years in the wild and reach sexual maturity at 4 to 5 years old. 
- For the similar species Paralithodes camtschatica (also known as Alaskan king crab), mating occurs once a year during spring immediately or soon after the female has molted. 
- Females of the species Paralithodes camtschatica carry eggs under their broad abdomen for 12 months, after which small larvae emerge from the eggs. 
- Found in depths from intertidal to 183 meters (600 ft). 
- The species Paralithodes camtschatica mainly feeds on mollusks and echinoderms. 
- Preyed on by the shortspine thornyhead. 
Traps and bottom trawls negatively impact the ocean floor as they are dragged by the ships that carry them.
- Available year round.
Regulatory and managing authority
- 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. [7,8]
- Several trap designs are used in the rock crab fishery. The most popular is a single chamber, rectangular trap of two-by-four- or two-by-two-in. welded wire mesh. 
Status of the fishery
- No fishery is designated specifically for this species, so little to no information on stock sizes, recruitment rates, effects of oceanographic regimes on this species. 
- There are no conservation concerns known for this species, but fishing pressure and global warming are thought to have reduced the population size of the related Alaskan king crab. 
Potential ecosystem impacts
- There may be issues of habitat damange and ghost fishing from lost traps.
- Specific information about this fishery is not known, but most crab traps are designed for release of immature crabs to avoid catching individuals before they are able to reproduce. 
Domoic acid, a product of harmful algal blooms, can be found in the viscera (guts) of certain crabs during blooms.
- Legs, muscle (meat) inside body walls; whole body may be used in broth and soup. 
- One of the highest meat-to-shell ratios, 3 pounds of whole crab yield around 2 pounds of meat. 
Description of meat
- Meat is soft, flaky, white, delicate, and sweet-tasting.
- Available live; Cooking instructions at reference. 
- Most often served by itself with a side of butter; can be used in pasta, crab-cake, sushi, etc.
- Nutritional information for 100g of raw Alaskan king crab (Paralithodes camtschatica) is displayed. 
- Although domoic acid, a naturally occuring toxin, is sometimes found in shellfish that occur in shallower waters ; this species is generally caught in deeper waters reducing risk of exposure to blooms.
- Avoid eating the viscera, where toxins can be concentrated.
- Available year round.
