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 SOFT-SHELL CLAM ( MYA ARENARIA ) DISTRIBUTION & ABUNDANCE AT SELECTED SITES IN THE GREAT BAY ESTUARY, NEW HAMPSHIRE A Final Report to The New Hampshire Estuaries Project Submitted by Raymond E. Grizzle, Jennifer K. Greene, and Holly Abeels University of New Hampshire Zoology Department and Jackson Estuarine Laboratory 85 Adams Point Road Sea surface temperatures in the current distribution of the soft-shelled clam range from a February minimum of -2.1 oC to an August maximum of 29.1 oC. Thermal criteria for Mya arenaria are from Kennedy and Mihursky (1971), Newell and Hidu (1986), Pfitzenmeyer, (1962), Stickney (1964), Distribution & Ecology.

It is the east coast of North America, but there is uncertainty about the northern as well as the southern limit. Previous surveys (1996 to 2002) provided distribution and abundance data for soft-shell clam (Mya arenaria) populations in ten areas of the Great Bay and Piscataqua River estuaries identified as potentially good clam habitat. The present study was designed to The bivalve Mya arenaria L. is a common inhabitant of intertidal sediments along the southcentral Alaskan coastline. Its current distribution along the Pacific coast of the continental USA, Canada and Alaska has resulted from a series of intentional and These animals are deep burrowers and the foot is positioned downwards, while the siphons reach straight up through sand or mud to the water above (M.

The Pacific and European populations became extinct some time in the early Pleistocene, leaving only the Northwest Atlantic population, which subsequently spread via humans to its current distribution. 1999-08-01 1998-09-01 2006-04-01 Linear growth of soft-shell clams, Mya arenaria L., was studied at six locations in the White Sea situated in the middle and low tidal zones. The main aim was to analyse the growth heterogeneity both within beds (with respect to individual growth) and between beds (with respect to group growth). Mya population was characterized by a slow growth and a long lifespan. The presence of Mya arenaria in the Ria de Aveiro is the third confirmed record of this invasive clam on the Portuguese coast - Volume 5 Soft-Shell Clam (Mya Arenaria) Distribution & Abundance at M.
