Development of 53 novel polymorphic EST-SSR markers for the hard clam
Meretrix meretrix and cross-species amplification.
As part of the restoration initiative, hard clam
seed will be supplied to one of five sanctuary sites that will be established here this fall, including Bellport Bay, Shinnecock Bay, Huntington Harbor, Hempstead Bay and South Oyster Bay.
Kraeuter (2001) described "Predators and Predation" in the Elsevier volume, Biology of the Hard Clam
. Newell et al.
maxima (Deng et al., 2014) and 3.10% in hard clam
Meretrix meretrix (Li et al., 2011), but lower than 10.22% in clam Paphia textile (Chen et al., 2016) and 4.7% in pearl oyster P.
The most commonly sought species is the hard clam
, which must be greater than an inch in thickness (measured perpendicular to the hinge holding the two shells together) to be kept legally.

"What was really interesting was that some of the creatures, the coral, the hard clam
and the lobster, for example, didn't seem to care about CO2 until it was higher than about 1,000 parts per million (ppm)," she added.
To identify other baits, the activity in the pallial nerve of whelks was determined during exposure of the osphradium to odorant solutions prepared from horseshoe crab eggs, horseshoe crab hemolymph, and hard clam
(Mercenaria mercenaria) tissue.
The eastern oyster and hard clam
are the most common types of bivalves, and both have become more prone to disease, likely due to poor water quality.
This study provides evidence that the hemocytes of the hard clam
proliferate directly at the inflammatory site, as opposed to a possible bone marrow-like area in the body of the clam, with subsequent migration of hemocytes to sites of infections, as seen in vertebrates.
In North Carolina estuaries, the hard clam
Mercenaria mercenaria generally shows lower growth rates in habitats where predation rates are higher.
First, I described spatial and seasonal patterns of predation on a common infaunal bivalve, the hard clam
Mercenaria mercenaria, exposed to the natural assemblage of predators in a lagoonal system of the eastern U.S.
