The Status Of Virginia’S Public Oyster Resource 2020, Melissa Southworth, Roger L. Mann
Reports
The Virginia Institute of Marine Science (VIMS) monitors recruitment of the Eastern oyster, Crassostrea virginica (Gmelin, 1791), annually from late spring through early fall, by deploying spatfall[1] (settlement and recruitment of larval oysters to the post metamorphic form termed spat) collectors (shellstrings) at various sites in three Virginia western Chesapeake Bay tributaries. The survey provides an estimate of a particular area’s potential for receiving a "strike" or settlement (set) of oysters on the bottom and helps describe the timing of recruitment events in a given year. Information obtained from this monitoring effort provides an overview of long-term recruitment …

Shoreline Management Handbook, Pamela Mason, Angela King, Clay Bernick
Reports
Shoreline habitats and processes are impacted by the decisions we make about managing coastal development and shorelines. Shoreline Management is making choices to address the desire to protect upland property from erosion or develop property balanced with the benefits and uses of natural and nature-based shoreline features and shoreline habitat restoration. This requires a weighing of the private benefits and cots of management actions and the benefits and costs to public held common resources, also known as the public trust. The natural features along our shorelines -tidal wetlands, beaches and dunes, and riparian buffers, are economically and ecologically valuable. They …

Reports
Prince George County is situated between on the James River between Upper Chippokes Creek and the Appomattox Rivers (Figure 1). Because the County’s shoreline is continually changing, determining where the shoreline was in the past, how far and how fast it is moving, and what factors drive shoreline change will help define where the shoreline will be going in the future. These rates and patterns of shore change along Chesapeake Bay’s estuarine shores will differ through time as winds, waves, tides and currents shape and modify coastlines by eroding, transporting and depositing sediments.

Monitoring Relative Abundance Of American Shad And River Herring In Virginia Rivers 2015 Annual Report, Eric J. Hilton, Robert Latour, Patrick E. Mcgrath, Brian Watkins, Ashleigh Magee
Reports
Concern about the decline in landings of American shad (Alosa sapidissima) along the Atlantic coast prompted the development of an interstate fisheries management plan (FMP) under the auspices of the Atlantic States Marine Fisheries Management Program (ASMFC 1999). Legislation enables imposition of federal sanctions on fishing in those states that fail to comply with the FMP. To be in compliance, coastal states are required to implement and maintain fishery-dependent and fishery-independent monitoring programs as specified by the FMP. For Virginia, these requirements include spawning stock assessments, the collection of biological data on the spawning run (e.g., age-structure, sex ratio, and …
