There are many reasons that it will be useful for students to have an understanding of the softshell clam (Mya arenaria) life cycle as they work as part of CSI-Maine. It will help them understand when clams are most vulnerable to predators, how long it takes for a clam to reach legal size, why there can be lots of seed clams even in areas where there are no adult clams, and much more.

It is ingested by its mollusc host, which is often an oyster of the genus Crassostrea. 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. Mya arenaria. Mya arenaria ; la cuticule externe disparait rapidement après la mort du coquillage, laissant nettement apparaître les stries de croissance. Ce mollusque sinupallié est protégé par une coquille équivalve aplatie, allongée, à l'ornementation assez faible.

Since 1988, only one year-class has dominated in the beds while other generations have been Erdman and Tennant (1956) showed an average of 85% reduction in the number of coliform bacteria in the soft-shell clam (Mya arenaria). The major problem associated with relaying is that it is a labor-intensive process, and up to 50% of the original harvest can be lost (Furfari, 1979).

It will help them understand when clams are most vulnerable to predators, how long it takes for a clam to reach legal size, why there can be lots of seed clams even in areas where there are no adult clams, and much more. However M. arenaria originated in the Pacific Ocean during the Miocene. It extended its range in the early Pliocene to the Atlantic, including European waters. 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.

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. The Mya arenaria bed under
In the Baltic Sea and its estuaries, water salinity is one of the key factors determining the occurrence, distribution, and abundance of species via its effect on the functional ecology of aquatic animals (e.g. growth rate, life cycles, production, and energy flows) (Kullenberg, 1991, Gogina and Zettler, 2010, Ojaveer et al., 2010, Bleich et al., 2011).
