Morphology, life cycles, enlargement in Ray's fluid thioglycolate medium (RFTM) (Ray 1952), and their Soft-shell clams Mya arenaria also known as steamers. Wild, with some hatchery supplementation (seeding of flats with juveniles). Soft-shell clams burrow 8-14 inches into mud, sand, and gravel intertidal areas from Labrador to North Carolina.

In eastern Maine, the spawning season extended from early June to the middle of Aug Dynamics of Mya arenaria beds in two bights of the Chupa Inlet (Kandalaksha Bay, White Sea) were studied on a long-term basis. Observations were carried out at 1– to 3-year intervals from 1979 up to 1999. The studied soft-shell clam beds were characterised by a substantial instability of age structure. Since 1988, only one year-class has dominated in the beds while other generations have Accepted name: Mya arenaria Linnaeus, 1758.

The mortality rate was found to change more than tenfold throughout the study period. No regular The mortality rate (μ) in this 1988 generation varied throughout the period of investigation and was related to age. The mortality level decreased for the first 2–4 years of the life cycle, then stabilised for the next 3–4 years, and eventually increased in subsequent years. Overall μ values ranged from 0 to 1.68 year–1. (Mya arenaria) along a latitudinal gradient. - ICES mar.

It then becomes a trophozoite, which proliferates in the tissues of the host. 2013-11-01 · In North America, a high mortality of soft-shell clams Mya arenaria was found to be related to the disease known as disseminated neoplasia (DN). Disseminated neoplasia is commonly recognized as a tetraploid disorder related to a disruption of the cell cycle.

Spawning/Larval Development. - Softshell clams typically have two spawns during a calendar year in the Chesapeake Bay, one in the spring and another during the fall. Both are triggered by temperatures in the 10-20oC range with optimal spawning temperatures 12-15oC.
