OES Theses and Dissertations

The annual net secondary production of the stout razor clam, Tagelous plebeius, was estimated at three sites on an intertidal sand flat at Lynnhaven Inlet, Virginia. Samples were taken at six week intervals for one year. The range of net production (P), mean annual biomass (B), and P/B ratios was 18.3-28.7 g m^-2year^-1, 27.2-53.3 g m^-2, and 0.54-0.67, respectively. The total biomass did not show significant seasonal variation though differences between sites were significant. Production varied temporally but was not significantly different between sites.
