potentially affect food resources and habitat of commercially important bivalves like quahogs, Mercenaria mercenaria, and softshell clams, Mya arenaria. To define how land-derived nitrogen loads and resulting eutrophication affect bivalves, we compared estuarine features to growth and survival of clams across estuaries receiving different N loads.

Habitat: In mud or sandy mud, sometimes mixed with gravel. Common in estuaries and other areas of reduced salinity (to as low as 23% seawater). Biology/Natural History: This clam has been introduced from the Atlantic, being first seen in San Francisco Bay in 1874. It slowly spread north, and reached Alaska in the 1950's.

Mya arenaria is highly vulnerable to climate change. Habitats Assigned to Softshell Clam: Formation Name Intertidal Macrogroup Name Intertidal Gravel Shore Habitat System Name: Lower Intertidal Macrogroup Name Intertidal Mudflat Habitat System Name: Non-Vascular Mudflat **Primary Habitat** Macrogroup Name Intertidal Water Column Shells of the oyster ( Crassostrea virginica ), soft-shelled clam ( Mya arenaria ), and surf clam ( Spisula solidissima ), stacked randomly in tanks, have worked well and demonstrate principles that could be used to develop a commercial substrate. Each habitat configuration supports a different size range of lobsters. Softshell Clam (Mya arenaria) Overall Climate Vulnerability Rank: Very High (58% certainty from bootstrap analysis). Climate Exposure: Very High. Three exposure factors contributed to this score: Ocean Surface Temperature (4.0), Air Temperature (3.5), and Ocean Acidification (4.0). Softshell Clam utilize near coastal and intertidal habitats.

Mya arenaria , soft-shelled clam Background Mya arenaria , the soft-shelled clam, is widespread in the Pacific (as an introduced species) and both sides of the North Atlantic. In the western Atlantic this species occurs from Labrador to Georgia. Abrahan and Dillon 1986 gave a useful account for the soft-shelled clam. Mya arenaria inhabits intertidal zones and subtidal depths to almost 200m from Labrador, Canada through Florida along the east coast of the United States and in Western Europe from Norway to the Black Sea. This species has been introduced along the Pacific coast of the United States, from Alaska through California. Mya arenaria is highly vulnerable to climate change.

This study emphasizes the ecological importance of horizontal advective processes for energy transfer from the pelagic to the benthic system. 1996-02-01 · In the semi-exposed habitat in the Skagerrak, Cerastoderma edule and Mya arenaria had a produc- tion equal to primary production.

Often very common in estuaries, where it may occur in extensive beds. Mya arenaria from the beach at Freeland, Holmes Harbor, Whidbey Island.

M. arenaria är en av tre arter Sandmusslor som förekommer i Sverige och den vanligaste. Henrik Munthe namngav 1910 Myahavet efter denna musselart, efter den tid i slutet av järnåldern då han antog att arten invandrat till Östersjön i samband med minskad salthalt.

Abstract. Mya arenaria currently occupies a wide geographical range in the northern hemisphere, on both coasts of the Atlantic as well as on the Pacific east coast. Some authors claim it also occurs on the Pacific west coast. The species originated in the Pacific during the Miocene and was already present on both Atlantic coasts in the Pliocene. However, it died out on the east coasts of the Pacific and the Atlantic during glaciation of the Pleistocene.

Eastern softshell clams have an elongated shell that is thin, brittle, and uneven on the outer surface. They grow to 6 inches long and are white or grey colored with dark siphon tips. Mya arenaria inhabits intertidal zones and subtidal depths to almost 200m from Labrador, Canada through Florida along the east coast of the United States and in Western Europe from Norway to the Black Sea. This species has been introduced along the Pacific coast of the United States, from Alaska through California.
