Presentation Abstract

Eastern oysters (Crassostrea virginica) provide ecological services in many estuaries. Individual physiological rates and scope for growth are influenced by ambient temperature, salinity, and food conditions. The seasonality of internal shell growth signature deposition in North Inlet estuary, South Carolina oysters was evaluated using quantitative and qualitative analyses of shells collected at monthly intervals. A cross-section along the growth axis of each left valve was used to measure the distance from the previous growth signature to the terminal edge, which was the newest growth increment at the time of collection. Distance measurements standardized to shell height (to correct for ontogeny) will be related to measured ambient habitat conditions during the growth interval. A deeper understanding of internal growth signatures and the effects of temperature, salinity, and food availability will thereby provide insight on local oyster growth patterns and the associated ecosystem services.
