Quantitative distribution of the king crab Paralithodes camtschatica in the southeastern Bering Sea, 1975-76. bivalve mollusks, but principally feeds on the Green- land cockle (Serripes groenlandicus: Lowry and Frost, Chapter 49, this volume). Sea stars are used as food by red king crab in shallow waters around Kodiak Island (Feder and Jewett 1981) and perhaps also by this crab in the Bering Sea. The distributions of two dominant sea-star species and red king crab in the southeastern Bering Sea (Figs. 69-10, 69-14, and 69-15) do not overlap appreciably; the biomass of sea stars is typically low where this crab is common. Sea stars may actively avoid red king crab in areas with dense populations of the crabs; an apparent avoidance response of sea stars (Pycnopodia helianthoides) to this crab in Kodiak waters is reported by Feder and Jewett (1981). Sea stars and red king crab feed on hard-shell clams whenever these are present; if Paralithodes ate sea stars they would be reducing competition for clam resources. A similar distribu- tional relationship between snow crabs and sea stars is not apparent. Snow crabs (Chionoecetes spp.) appar- ently do not feed on sea stars; thus, asteroids and snow crabs coexist in the Bering Sea (Figs. 69-9, 69-14, and 69-15). Sea stars and snow crabs do not generally compete for food; Chionoecetes spp. feed on a variety of small invertebrates rarely used by sea stars. The role of gametes as a source of carbon has been.
