Preface.(oyster fisheries)(Editorial)
May 1, 2008... The collapse of the fishery for native oysters (Crassostrea virginica) in Chesapeake Bay, USA has fueled interest in the introduction of an exotic species to revitalize a fishery and, more recently, recover lost ecosystem services. Beginning in...

Identification of Crassostrea ariakensis and related oysters by multiplex species-specific PCR.(polymerase chain reaction)(Report)
May 1, 2008... ABSTRACT Genetic markers are needed for rapid and reliable identification of oysters. In this study, we developed multiplex genus- and species-specific PCR markers for the identification of oysters from China. We used the mitochondrial...

Its length polymorphism in oysters and its use in species identification.(Report)
May 1, 2008... ABSTRACT In an effort to develop genetic markers for oyster identification, we studied length polymorphism in internal transcribed spacers (ITS) between major ribosomal RNA genes in 12 common species of Ostreidae: Crassostrea virginica, C....

Classification of common oysters from North China.(Report)
May 1, 2008... ABSTRACT Oysters are commonly found on rocky shores along China's northern coast, although there is considerable confusion as to what species they are. To determine the taxonomic status of these oysters, we collected specimens from nine...

Suminoe oyster (Crassostrea ariakensis) culture in Korea.(Report)
May 1, 2008... ABSTRACT The Suminoe oyster Crassostrea ariakensis is considered a potential aquaculture species in Korea, potentially supplementing or supplanting culture of the Pacific oyster Crassostrea gigas, currently the focus of commercial production...

Crassostrea ariakensis in Chesapeake Bay: growth, disease and mortality in shallow subtidal environments.(Report)
May 1, 2008... ABSTRACT In April 2004, triploid native (Crassostrea virginica) and nonnative (Crassostrea ariakensis) oysters were deployed in cages at four sites along a salinity gradient in Chesapeake Bay. In Maryland, the lowest salinity site was located...

Characteristics of crassostrea ariakensis (Fujita 1913) and Crassostrea virginica (Gmelin 1791) in the discharge area of a nuclear power plant in Central Chesapeake Bay.(Report)
May 1, 2008... ABSTRACT Since 1978, the Maryland Department of Natural Resources has investigated the uptake and depuration by C. virginica of radionuclides released by the Calvert Cliffs Nuclear Power Plant (CCNPP), which is located on the western shore of...

Estimation of annual mortality rates for eastern oysters (Crassostrea virginica) in Chesapeake Bay based on box counts and application of those rates to project population growth of C. virginica and C. ariakensis.(Report)
May 1, 2008... ABSTRACT In an effort to restore the ecological role of oysters in Chesapeake Bay and the economic benefits of a commercial fishery, the states of Maryland and Virginia are considering introducing the nonnative Asian oyster (Crassostrea...

Effects of salinity on Bonamia sp. survival in the Asian oyster Crassostrea ariakensis.(Report)
May 1, 2008... ABSTRACT A novel Bonamia sp. discovered in Bogue Sound, NC, has recently emerged as a parasitic threat to the Asian oyster Crassostrea ariakensis. Because this oyster is being considered for introduction to the mid-Atlantic region, more data...

Susceptibility of Crassostrea ariakensis (Fujita 1913) to Bonamia and Perkinsus spp. infections: potential for disease transmission between oyster species.
May 1, 2008... ABSTRACT Using PCR-based methodologies, we surveyed triploid Crassostrea ariakensis (Fujita 1913), introduced in experimental trials in the Chesapeake Bay, for parasites endemic to the native oyster and for Bonamia ostreae. Perkinsus sp. was...

Differential production of feces and pseudofeces by the oyster Crassostrea ariakensis when exposed to diets containing harmful dinoflagellate and raphidophyte species.(Report)
May 1, 2008... ABSTRACT The Asian oyster, Crassostrea ariakensis, is being evaluated for its potential success in the restoration of oyster populations in Chesapeake Bay. Critical to an understanding of its potential success is knowledge of the impacts of...

Responses of Crassostrea virginica (Gmelin) and C. ariakensis (Fujita) to bloom-forming phytoplankton including ichthyotoxic Karlodinium veneficum (Ballantine).(Report)
May 1, 2008... ABSTRACT In the last several decades, the Eastern oyster (Crassostrea virginica) fishery in Chesapeake Bay has collapsed, largely because of overfishing and disease. As a consequence, there is increasing interest in the introduction of the...

Fertilization interference between Crassostrea ariakensis and Crassostrea virginica: a gamete sink?(Report)
May 1, 2008... ABSTRACT Published data indicate that spawning seasons for the Asian oyster Crassostrea ariakensis and the eastern oyster C. virginica overlap. Hybrids can form, but the larvae are not viable. If C. ariakensis is introduced into Chesapeake Bay...

Settlement of crassostrea ariakensis larvae: effects of substrate, biofilms, sediment and adult chemical cues.(Report)
May 1, 2008... ABSTRACT The Suminoe oyster (Crassostrea ariakensis) is being considered for introduction into the Chesapeake Bay. However, our current understanding of the biology and ecology of C. ariakensis is insufficient to predict whether an introduction...

Post-settlement survival and growth of the suminoe oyster, Crassostrea ariakensis, exposed to simulated emersion regimes.(Report)
May 1, 2008... ABSTRACT In high salinity habitats along the Middle and South Atlantic coasts of the United States the Eastern oyster, Crassostrea virginica occupies an intertidal refuge from predation, facilitated by its tolerance of aerial exposure and...

Economic benefits of a restored oyster fishery in Chesapeake Bay.(Report)
May 1, 2008... ABSTRACT A simple reduced form inverse demand model is used to determine the price flexibility of Chesapeake Bay oyster production when other producing regions of the United States have their oyster production held at average levels for 2002 to...
