Identification of host-defense genes and development of microsatellite markers from ESTs of hard clam
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.
There are two species of hard clam
in Florida: the northern quahog (Mercenaria mercenaria) and the southern quahog (Mercenaria campechiensis).
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.
But in the industry, the term quahog is used from the Canadian Maritimes through Rhode Island, while simply clam or hard clam
is used from Connecticut through Texas; in Mexico, it is the almeja (clam).
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.
95) has the kitchen joining a spicy tomato and vegetable blend with chopped seafood for great taste, though the texture of the overly hard clam
bits could be improved.
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.
Habitat-specific growth of hard clam
Mercenaria mercenaria (L.
