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 ...

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 ...

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 ...

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, ...

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 ...

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 ...
