A food web showing carbon flow to king crab (Paralithodes camtschatica) in the eastern Bering Sea. Bold lines indicate major food sources. Primary foods were mollusks (bivalves: percent in males and percent in females), echinoderms (asteroids, ophiuroids, and echinoids: percent in males and percent in females), and decapod crustaceans (shrimps: 26 percent in males and percent in females). Polychaetes, algae, and other crustaceans were next in descending order of impor- tance. In general, foods were not found to be signifi- CEintly different between the sexes. Feder and Jewett (1980) examined the food of adult red king crab from the southeastern Bering Sea. The dominant prey items, in decreasing percent frequency of occurrence, were a cockle (Clinocardium ciliatum), a snail (Solariella sp.), a clam (Nuculana fossa), brittle stars (Amphiuridae), a polychaete worm (Cistenides sp.), and snow crabs (Chionoecetes spp.). Feniuk (1945) found mollusks, crustaceans, and polychaetes, in descending order of importance, to be the main foods of red king crab from the west Kamchatka shelf. Takeuchi (1959, 1967) determined that mollusks, crustaceans, and echinoderms, in decreasing order of importance, were the major prey of red king crab of the west Kamchatka coast. Kun and Mikulich (1954) and Kulichkova (1955) exam- ined red king crab from the extreme western Bering Sea. They concluded that the diet of this crab differs according to geographic region and that the crab feed on the dominant benthic forms. The most common food groups we
