1983), whereas the feeding activity of small (final shell length, 1-3 mm) juvenile Mercenaria mercenaria
fed "on demand" demonstrated that larger animals in the second week of culture achieved satiation at a reduced ration compared with the initial week (Coutteau et al.
These growth increments are similar in form to those in Mercenaria mercenaria
: they are composed of a thin line followed by a broad increment.
Cross-species amplifications of the microsatellite loci were conducted in three other species, including Mercenaria mercenaria
, Gomphina aequilatera, and Meretrix lyrata, belonging to three genuses in the family Veneridae (Bivalvia: Mollusca) (Fig.
Effects of brown tide (Aureococcus anophagefferens) on hard clam Mercenaria mercenaria
larvae and implications for benthic recruitment.
Development and characterization of polymorphic microsatellite markers for the northern quahog Mercenaria mercenaria
Adult Mercenaria mercenaria
(mean shell length, L = 78.6 mm [+ or -] 5.5 mm standard deviation, SD) were obtained from natural populations in St.
In addition, hard clam (Mercenaria mercenaria
) landings in the estuary declined by more than 95% over the 30-year period from 1975 to 2005.
As part of these efforts, the sensitivities of knobbed and channeled whelks to odorant solutions prepared from horseshoe crab eggs, horseshoe crab hemolymph, and hard clam (Mercenaria mercenaria
) tissue were examined.
The beads were made from the shell of the quahog clam, with the scientific name Mercenaria mercenaria
, from the Latin word for money.
In North Carolina estuaries, the hard clam Mercenaria mercenaria
generally shows lower growth rates in habitats where predation rates are higher.

Genetic and shell morphology in a hybrid zone between the hard clams Mercenaria mercenaria
An example is the hard clam Mercenaria mercenaria
, where unsustainable fishing mortality led to recruitment overfishing in both North Carolina and New York (Peterson 2002, Kraeuter et al.
The names are merely size designations for the same critter, which is the hardshell clam, Mercenaria mercenaria
. "Quahog" is used both as the collective name and as a label for the biggest size.
Gallager and Mann (1986) found that repeated spawning of the same broodstock of the bivalve Mercenaria mercenaria
over an extended time had detrimental effects on egg characteristics and larval survival from those adults.
