Distribution patterns and biology of ocean quahogs in the Mid-Atlantic Bight (MAB) off the east coast of North America are directly related to bottom water temperatures. We examined long term recruitment patterns for ocean ...
Harvest history and current densities of the pearl oyster Pinctada mazatlanica (Bivalvia: pteriidae) in Las Perlas and Coiba Archipelagos, Panama.(Report)
Aug 01, 2008; Cipriani, Roberto ... ABSTRACT Four hundred years of commercial harvest of the oyster Pinctada mazatlanica in Pacific Panama were characterized by historical collapses and recoveries that finally ended in the 1940s; oyster populations have not recovered since then. This study provides a baseline and ...
Larval quality of a nonnative bivalve species (European oyster, Ostrea edulis) off the east Canadian coast.(Report)
Aug 01, 2008; Burke, Kevin ... ABSTRACT A population of European oysters (Ostrea edulis) was recently discovered off the eastern coast of Canada. The occurrence of this newly established population led various aquaculture stakeholders to consider this species commercially. To better assess recruitment capacity, the ...
Prospective culture of the Cortez oyster Crassostrea corteziensis from northwestern Mexico: growth, gametogenic activity, and condition index.(Report)
Aug 01, 2008; Chavez-Villalba, Jorge ... ABSTRACT This study examined growth, gametogenic activity, condition index, as well as the relationship of the life cycle to environmental parameters of the Cortez oyster Crassostrea corteziensis, which was cultured for 25 mo in the lagoon of Las Guasimas (Sonora, Mexico). We used oocyte ...
Assessment of genetic diversity of the eastern oyster Crassostrea virginica in Veracruz, Mexico using microsatellite markers.(Report)
Aug 01, 2008; Galindo-Sanchez, Clara E. ... ABSTRACT Genetic variation was evaluated in populations of the eastern oyster Crassostrea virginica (Gmelin) from the coast of Veracruz, eastern Gulf of Mexico. We sampled six lagoons and analyzed variation at five microsatellite loci. Significant Hardy-Weinberg deviations occurred at all ...
Long-term trends in oyster population dynamics in Delaware Bay: regime shifts and response to disease.(Report)
Aug 01, 2008; Powell, Eric N. ... ABSTRACT We evaluate a 54-y survey time series for the Delaware Bay oyster beds in New Jersey waters to identify the characteristics of regime shifts in oyster populations and the influence of MSX and Dermo diseases on population stability. Oyster abundance was high during the 1970s ...
A comparison of the macrofaunal communities inhabiting a Crassostrea virginica oyster reef and oyster aquaculture gear in Indian River Bay, Delaware.(Report)
Aug 01, 2008; Erbland, Patrick J. ... ABSTRACT The eastern oyster (Crassostrea virginica) is a vital species in the estuaries of the mid-Atlantic United States. Whereas their filtering activity and biodeposition play an important role in the ecology of these systems, the reefs they form are one of the few sources of hard ...
Effects of triclosan on the oyster parasite, Perkinsus Marinus and its host, the eastern oyster, Crassostrea virginica.(Report)
Aug 01, 2008; Chu, Fu-Lin E. ... ABSTRACT Because temperature plays an important role on progression and transmission of disease caused by Perkinsus marinus in the field, the effects of triclosan on the viability of P. marinus meronts (trophozoites) and oyster hemocytes were tested at a range of environmental relevant ...
Recovery of a fish pathogenic bacterium, Aeromonas salmonicida, from ebonyshell mussels Fusconaia ebena using nondestructive sample collection procedures.(Report)
Aug 01, 2008; Starliper, Clifford E. ... ABSTRACT Refugia are increasingly being used to maintain and propagate imperiled freshwater mussels for future population augmentations. Success for this endeavor is dependent on good husbandry, including a holistic program of resource health management. A significant aspect to optimal ...

Experimental manipulation of suspended culture socks: growth and behavior of juvenile mussels (Mytilus spp.).(Report)
Aug 01, 2008; Senechal, Judith ... ABSTRACT Suspended mussel culture entails loading high densities of juvenile mussels into mesh socks, and hanging them from floating longlines, often resulting in intraspecific crowding, reduced growth, and mussel yield. Despite this potential bottleneck in culture, there are few data on ...
