Chionoecetes bairdi is a species of snow crab, alternatively known as bairdi crab and tanner crab. C. bairdi is closely related to Chionoecetes opilio, and it can be difficult to distinguish C. opilio from C. bairdi. Both species are found in the Bering Sea and are sold commercially under the name "snow crab."
Chionoecetes opilio crabs eat other invertebrates in the benthic shelf, such as crustaceans, bivalves, brittle stars, polychaetes, and even phytobenthos and foraminiferans. Snow crabs also are scavengers, and aside from preying on other benthic shelf invertebrates, they prey on annelid worms and mollusks.
Common names for crabs in this genus include "queen crab" (in Canada) and "spider crab". The generic name Chionoecetes means snow ( χιών , chion ) inhabitant ( οἰκητης , oiketes ); [ 3 ] opilio means shepherd , and C. opilio is the primary species referred to as snow crab.

Several theories for the precipitous drop in the crab population have been proposed, including overfishing, warmer waters, and increased fish predation. The slow harvest forced many fishermen to diversify and catch snow crab (such as opilio and tanner crab) or cod. Since then, strict regulations have been enforced to responsibly manage the ...
