An adaptive approach to enhance eastern oyster (Crassostrea virginica) in the Piankatank River, Chesapeake Bay, Virginia
Piankatank River oyster population density and biomass estimates
Average oyster density (number per square meter) and biomass (g dry tissue weight per square meter) were calculated from patent tong survey data collected on natural oyster bars in the Piankatank River. Abbreviations used in the table below are as follows: Avg = average, SEM = standard error of the mean
