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.

Mya arenaria Softshell clam. Species Description. The softshell clam is a marine/estuarine bivalve species of the Family Myidae. This species attains a maximum shell length of about 15 cm (10-11 in the Chesapeake Bay), with an oval, elongated shell ranging from white to dark grey in color.

The softshell clam, Mya arenaria, is widely distributed in coastal and intertidal soft substrates in boreal waters and is often a dominant species in benthic Soft shell clams (Mya arenaria) are bivalves native to the east coast of North America. The distribution of resistant clams is not random among populations.

Distribution and habitat. This species is widespread over the Arctic seas and extends to the Bay of Biscay, to the West Atlantic coast and to Sakhalin on the Pacific coast. It has been reported also in the waters around Japan. Mya truncata lives from the lower shore up to depths of 70 m, burrowed in sand or sandy mud. Gallery

However, the taxonomic history of this species includes many synonyms, overlapping descriptions, and/or subspecies (e.g. Mya hemphilli, Mya arenomya arenaria, Winckworth 1930; Bernard 1979).

We collected 266 samples spanning a latitudinal cline from the Mediterranean to the North Sea and genotyped them at 12 microsatellite loci. In parallel, geometric morphometric analysis of shell outlines was and costly monitoring programs. The soft-shell clam, Mya arenaria L., is a native species with a wide latitudinal distribution along theAtlantic coast of North America, from Labrador, Newfoundland, to Georgia (Strasser 1999), which overlaps with areas affected by red tides.
