Biological synopsis of the Asian shore crab, Hemigrapsus sanguineus / by G. Klassen. : Fs97-4/2978E-PDF

"The Asian shore crab is native to northern Asia, from Sakhalin Island (Russia) to Taiwan, where it experiences water temperatures of <0°C in winter to 28°C in summer. It has established populations in the Atlantic from North Carolina to central Maine and from the English Channel to Germany, and has been reported from the Black Sea and northern Adriatic Sea. The species is not yet found in eastern Canada, but its potential distribution may include the Bay of Fundy and southern Nova Scotia. Natural dispersal is by planktonic larvae and benthic adults and juveniles. Shipping vectors have been implicated in anthropogenic dispersal. Low-energy, intertidal, boulder/cobble beaches are the characteristic native habitat. In North America, the crabs also utilize sand/pebble beaches, mussel beds, eelgrass beds, salt marshes, and artificial structures including aquaculture gear. The diet of the Asian shore crab includes algae, marine grasses, and invertebrates. Competition has been reported with native crabs that inhabit intertidal and subtidal habitats"--Abstract, page v.
