Horsehair crab

The horsehair crab, Erimacrus isenbeckii (Japanese: ケガニ, kegani), is a species of crab which is found mainly in the Northwest Pacific, around the Hokkaido coast in the Sea of Okhotsk and the Western Bering Sea and is an important commercial species used in Japanese cuisine. Despite the importance of the species, biological studies are usually specialized and limited. The catch for the species reached a peak in the 1950s at 27,000 tons and has decreased since, reaching 2,000 tons in 2003. Due to the commercial importance of the species, many stock enhancement programs have been utilized to help maintain a successful fishery. The species is commonly found on sandy benthic environments from shallow water to depths of up to 350 meters.
