Two other species of the genus {P. platy- pus and P. brevipes) are taken (Fig. 365) in small numbers along with the Kamchatka crab. The other two species of this genus are not found in Soviet waters. Only some of the smaller sized true crabs (Chionoecetes opilio, Erima- crus isenbecki and Telmessus cheiragonus) might become important commer- cially. So far, however, their role in the catch is insignificant. Kamchatka crab is taken almost throughout the whole area of its distribution (L. Vinogradov,. Fig. 365. Places of concentration of commercial crabs (Vinogradov). 1 Paralithodes camschatica; 2 P. platypus; 3 P. brevipes. 1941, 1945). P. brevipes has a similar area of distribution. The other four species are found from the Bering Sea to the Sea of Japan. The largest crabs belong to the genus Paralithodes, which forms large aggregations of commer- cial importance. Kamchatka crab assembles off the shores of the , Japan and Alaska. The largest yield of this crab is taken off the western coast of Kamchatka. Seasonal migrations of the Kamchatka crab consist of travel- ling to the coast (at depths of 15 to 70 m) for feeding during the summer, and a return to lower layers (110 to 200 m), and even down to 270 m in the Sea of Japan, where the water is better heated (1-5° to 2-5°) during the cold months when the surface waters are much cooled. The migration routes of the Kam- chatka crab cover dozens of miles (up to 100). The average daily distance.
