Abstract Oyster size and morphology affect individual oyster physiology, reproductive biology, and habitat production as well as population ecological services and availability for commercial harvest. Options for oyster restoration and fishery facilitation for eastern oyster (Crassostrea virginica) populations in the Chesapeake Bay include the use of disease resistant diploid eastern oysters (DEBY strain), triploid eastern oysters, and triploid Suminoe oysters (Crassostrea ariakensis) with the… Expand
Triploid Oysters in the Chesapeake Bay: Comparison of Diploid and Triploid Crassostrea virginica
TLDR
The notion that selective breeding programs to reduce mortality, coupled with triploid production to increase growth, can further optimize yield is supported, as well as the first clear illustration of variation for the cumulative mortality exhibited among different spawns in triploids. Expand
Early Post-Settlement Growth in Wild Eastern Oyster (Crassostrea virginica Gemlin 1791) Populations
TLDR
Following growth of wild oysters set on planted clamshells in Delaware Bay, this work document early growth (within the first year) of 21 wild oyster cohorts settling over 8 years and assess the importance of interannual variability in temperature and salinity. Expand
Evaluating the Potential Growth Advantage of Triploid Eastern Oysters (Crassostrea virginica) in South Carolina Relative to Commercially Cultured Diploid Native Stocks
TLDR
The results of this study are important for the commercial shellfish industry in South Carolina through its demonstration that current triploid technology has the ability to create a quality oyster product, within a timeframe that avoids the intense period of oyster recruitment in the spring. Expand
Effects of ploidy and gear on the performance of cultured oysters, Crassostrea virginica: Survival, growth, shape, condition index and Vibrio abundances
TLDR
It is concluded that oyster farmers could expect to benefit from raising triploid oysters, but that the magnitude of these benefits will depend on the type of gear selected. Expand
Genetic and environmental influence on triploid Crassostrea virginica grown in Chesapeake Bay: Growth
TLDR
Genotype × environmental response of triploids indicates that breeders may have to tailor crosses to suit particular areas interested in using triploid oysters, and breeding efforts can improve diploid field performance to rival Triploids. Expand
A meta-analysis of growth rate in diploid and triploid oysters
TLDR
A meta-analysis of 29 published studies using triploid oysters produced by chemical induction or by crossing diploid and tetraploid Oysters found that mated triploids grew 20% faster than diploids in shell height and 49% faster in whole wet weight. Expand
A comparative analysis of the growth, survival and reproduction of Crassostrea hongkongensis, Crassostrea ariakensis, and their diploid and triploid hybrids
TLDR
The first report of a systematic comparative study on the two native sympatric oysters of southern China, C. hongkongensis and C. ariakensis, confirms the clear advantages of HA and HHA in terms of growth traits and viability and provides promising evidence of their potential value as new variants for use in farming.

Observations on Age and Growth of the Eastern Oyster Crassostrea virginica in South Carolina Saltmarsh Tidal Creeks
ABSTRACT The eastern oyster Crassostrea virginica contributes important ecological and structural elements to estuarine ecosystems worldwide. Oyster reef persistence requires regular recruitment asExpand
Shell Length-at-age Relationships in James River, Virginia, Oysters (Crassostrea virginica) Collected Four Centuries Apart
TLDR
Compared population demographics and age-at-shell length relationships for modern mesohaline James River oyster populations withJames River oysters collected in the years 1611 to 1612 by Jamestown settlers, historic oyster collections made by hand included a more complete demographic than modern samples collected with patent tongs. Expand
Lethal and sublethal effects of sediment burial on the eastern oyster Crassostrea virginica
Eastern oysters Crassostrea virginica are dominant ecosystem engineers that construct complex reefs in estuarine systems. Reef persistence relies on reef growth, which must outpace reef degradationExpand

AGE AND GROWTH OF WILD SUMINOE (CRASSOSTREA ARIAKENSIS, FUGITA 1913) AND PACIFIC (C. GIGAS, THUNBERG 1793) OYSTERS FROM LAIZHOU BAY, CHINA
TLDR
Shell height at age estimates from Suminoe and Pacific oysters from a natural oyster reef in Laizhou Bay, China were compared with shell height atAge estimates from triploid C. ariakensis and C. gigas oysters to show fast growth appears to continue through at least age 4 or age 5 in wild individuals.

Growth patterns in oysters, Crassostrea virginica, from different estuaries
TLDR
Persistent differences between oyster strains from different origins over several generations support a hypothesis that these estuarine populations have experienced long-term genetically-based population differentiation. Expand
The American oyster,Crassostrea virginica gmelin
TLDR
The family Ostreidae consists of a large number of edible and nonedible oysters, confined to a broad belt of coastal waters within the latitudes 64° N. and 44° S, with few exceptions oysters thrive in shallow water. Expand
OYSTER GROWTH ANALYSIS: A COMPARISON OF METHODS
TLDR
In general, oysters in higher salinity portions of the Delaware Bay seed beds grew faster than those in the lower salinity regions, and these data indicate more rapid growth in the northern Gulf of Mexico than in other locals. Expand
Growth of tray-cultured oysters (Carssostrea virginica Gmelin) in Chesapeake Bay
TLDR
The rates measured during the growing season suggest that oysters could be grown to market size in 6 months of continuous active growth. Expand

IS OYSTER SHELL A SUSTAINABLE ESTUARINE RESOURCE?
TLDR
A model that expressly and conjointly evaluates oyster abundance and surficial shell quantity is developed and whether stability in the stock and the habitat can be simultaneously achieved andSimulations suggest that a steady-state shell content exists for any set of recruitment and natural mortality rates and that the amount of shell present at steady state varies over a wide range as recruitment andnatural mortality vary.

Stable isotope sclerochronology of Pleistocene and Recent oyster shells (Crassostrea virginica)
TLDR
Examining delta 18 O and delta 13 C profiles across ligamental increments found in Crassostrea virginica shells from the recent of Terrebonne Bay, Mississippi Delta, and the Pleistocene of Chesapeake Bay, Virginia demonstrates that stable isotope sclerochronology of oyster shells facilitates the interpretation of past estuarine environments and oyster life histories.

Energy flow in an intertidal oyster population
Abstract The numbers (1000–4400 individuals/m 2 ) and biomass (1548–2513 kcal/m 2 ) of an intertidal oyster population are shown to be very high for a macro-invertebrate population. The populationExpand
WHY OYSTER RESTORATION GOALS IN THE CHESAPEAKE BAY ARE NOT AND PROBABLY CANNOT BE ACHIEVED
TLDR
The argument is proffered that stabilizing the present bed footprint with a realistic and sustainable population and the promotion of aquaculture to increase commercial yield is a more predictable and stable economic investment and should take priority in future efforts. Expand
