The eastern oyster Crassostrea virginica is a temperate reef‐building bivalve that provides an array of ecosystem services. Efforts to restore eastern oyster have been increasing, highlighting the need for standardized monitoring metrics across projects and regions. Our objective was to estimate the efficiency of hydraulic patent tongs for estimating eastern oyster density on restoration sites in Harris Creek, Maryland. We sampled eastern oysters using a diver and hydraulic patent tongs and estimated differences in density estimates between the two gears using a mixed‐effects generalized linear model. On average, density estimates from hydraulic patent tongs were only 30% of those from the diver, which was substantially lower than previous studies. Given the widespread use of hydraulic patent tongs in eastern oyster research and management, a better understanding of the efficiency of hydraulic patent tongs is needed.

“…The disarticulation rate for boxes is also uncertain, resting on a very small sample size that identifies a relatively wide range of box half-lives (Christmas et al 1997;Pace et al 2020a;as inferred from Ford et al 2006), yet boxes provide an important source of ESA. As boxes are also used for the direct measurement of mortality rate (Ford et al 2006;Powell et al 2008;Vølstad et al 2008;Summerhayes et al 2009;Doering et al 2021), well-constrained estimates of disarticulation rates are urgently needed. Parameterization of the box disarticulation rates used conforms with observations from direct measurements and time series data for Delaware Bay.…”

Populations of the eastern oyster (Crassostrea virginica) have experienced declines from overfishing and disease throughout much of its U.S. range, though development of maximum sustainable yield (MSY) management criteria has been elusive. This is due in part to the discordance between oyster spawning stock and recruits as the classic stock-recruitment model does not account for the requirement of shell substrate on which recruits settle. This issue was recently addressed with the development of a surface area-recruitment model, which is herein incorporated into a simulation analysis to estimate MSY-based reference points for C. virginica in the Delaware Bay. Simulations demonstrate that at low natural mortality, fishing mortality (F) may be sustainable at values between 10 and 15%, however if disease or other mortality-enhancing processes occur, the margin of error in fishing is small and may quickly lead to population and reef collapse, emphasizing a precautionary F < 10%. The MSY-based reference points generated here provide rebuilding goals for the oyster fishery and reef management on fished and unfished reefs, and the framework from which shell-planting can be incorporated and optimized in the future.
