Oyster Marking Methodology Study

We are developing methods to imprint oysters with a non-toxic fluorochrome dye to give scientists, aquaculturists, health officials, and enforcement agencies the ability to positively re-identify marked oysters. Why We ...

Testing Feasibility of Directly Seeding Oyster Ree...

We are testing the feasibility of "direct setting," a new method for seeding oyster reefs. Traditional reef seeding in areas with low natural-recruitment uses hatchery-produced juvenile oysters attached to cultch ...

Assessment of River Herring Spawning Runs in a Chesapeake Bay Coastal Plain Stream using Imaging Sonar

Recent declines in anadromous river herring (Alewife Alosa pseudoharengus and Blueback Herring A. aestivalis) have been documented in much of their range using fishery‐independent spawning run counts. A lack of rigorous long‐term run counts and demographic data for Chesapeake Bay ...

Coastal Ecological Assessment to Support NOAA’s Choptank River Complex Habitat Focus Area: Tred Avon River

In the Tred Avon River, an important tributary of the Choptank River, we assessed the impacts of land use on the health of the aquatic ecosystem in a 3-year field study (2015-2017). In our analysis of information collected during the ...

Direct Setting of Eastern Oyster (Crassostrea virginica) Larvae Confirmed with Calcein, a Fluorochrome Dye

Ongoing efforts to restore eastern oyster (Crassostrea virginica) populations in regions of low natural recruitment rely on stocking of juveniles (spat on shell) to rebuild populations. Often, remote setting is used, entailing releasing hatchery-produced larvae into recirculating tanks filled with ...

Influenza A Virus Detected in Native Bivalves in Waterfowl Habitat of the Delmarva Peninsula, USA

We evaluated the prevalence of influenza A virus (IAV) in different species of bivalves inhabiting natural water bodies in waterfowl habitat along the Delmarva Peninsula and Chesapeake Bay in eastern Maryland. Bivalve tissue from clam and mussel specimens (Macoma balthica, ...

Marking the shells of juvenile and adult eastern oysters, Crassostrea virginica, with the fluorochrome dye calcein and measuring growth and mortality after marking

Techniques for positive re-identification of finfish are well developed and are used to estimate vital rates, migration patterns and stock structure. Fluorochrome dyes, like nontoxic calcein, have been used with success to mark hard parts of fish and the shells ...

Marking the Shells of Pediveliger Eastern Oysters Crassostrea Virginica, with a Calcein Fluorochrome Dye

The continued development of effective mark and recapture tools for marine invertebrates is required to better understand fundamental planktonic processes such as larval transport and mortality. Mass chemical marking methods provide researchers with the ability to mark large quantities of ...
