mercenaria is an EG II species (Table 2), so, as with Mya arenaria
, this species' response is predicted to be indifferent to nutrient enrichment.
As the slugs age, morula-like amoebocytes appear in the circulatory system that are similar in morphology to a fatal hemocyte neoplasia in the soft-shell clam, Mya arenaria
(Mondy and Pierce, 2003).
The clam disease was first noticed in the 1970s when soft-shell clams (Mya arenaria
) in the Chesapeake Bay and in Maine started dying in large numbers.
Thus far, two p53 family members (p53 and p73) have been sequenced in soft-shell clams (Mya arenaria
) (9), and one (p73) in squid (Loligo forbesi) (10).

) from the shore of the Gulf of Finland (Pirita Bay, North Estonia);
The softshell clam, Mya arenaria
L., is an infaunal, suspension-feeding bivalve that occurs intertidally and in shallow subtidal soft sediments in the Northwest Atlantic from Labrador, Canada, to Cape Hatteras, NC (Abbott 1974).

In this study, we provide protocols for culturing CCH from a naturally occurring disease in the soft shell clam, Mya arenaria
Linnaeus, in which highly conserved homologs for human wild-type p53 family proteins (GenBank Accession numbers: p53-like, AF253323; p63/73-like, AF253324) are nonfunctional because they are sequestered in the cytoplasm of CCH (Kelley et al., 2001; Walker et al., 2006; Bottger et al., 2008).
In a pilot mesocosm study conducted in June 2013, Carcinus maenas consumed varying sizes of Mya arenaria
, Macoma balthica, and Mercenaria mercenaria, and thus these sizes were used as a guideline for the feeding preference experiments.
Primers p53F1 (5'-CTACAACATGGACTTATTCT-3') and p53R1 (5'-TGCTTTTCTATCTCTTC-3') were designed to the conserved p53 DNA-binding region from alignments (Clustal X; Thompson et al., 1997) of DNA sequences of arrow squid (Loligo forbesi; GenBank accession number U43596) and clam (Mya arenaria
; GenBank accession numbers AF253323 and AF253324).
ABSTRACT During the past 40 y, commercial production of softshell clams, Mya arenaria
, in the soft-bottom intertidal zone in Maine, United States, has decreased nearly 75% whereas dockside revenues have increased ca.
