Image DB_WH_DSCF2802. Oyster (Crassostrea virginica) aquaculture site in Wellfleet Harbor at tidal height of -0.8 ft (-0.24 m). Black mesh bags containing oysters are tipped up on metal racks. Colonies of Didemnum vexillum (tan color) are encrusting mesh bags and oysters inside bags; red sponge and orange bryozoan also encrust the bags. Site is subtidal except at lowest tides. Wellfleet Harbor off Mayo Beach (approx. 41 deg 55.52 min N, 70 deg 02.41 min W). Maximum tidal range 11 to 12 feet (3.3 to 3.6 m). November 14, 2005. Collected by A. Cummings. Identified by P.
