Scaling Ecosystem Services To Reef Development : Effects Of Oyster Density On Nitrogen Removal And Reef Community Structure, Lisa M. Kellogg, Jeffrey C. Cornwell, Michael S. Owens, Mark W. Luckenbach, Paige G. Ross, Thomas A. Leggett

Reports

Eighteen native oyster experimental reefs (16-m2 each) were restored using six oyster densities (0, 10, 25, 50, 100 and 250 adult oysters m-2) with three replicates of each density at each of two sites: one subtidal site in Onancock Creek, Virginia and one intertidal site in Hillcrest Oyster Sanctuary within The Nature Conservancy’s Virginia Coast Reserve. A science-based monitoring program explored quantitative relationships between structural and functional characteristics of these restored reefs. Structural parameters examined included oyster abundance, oyster size/biomass, surface shell volume, reef topographic complexity and sediment characteristics. Functional parameters included denitrification rates and macrofaunal abundance and ...


Evaluating Recruitment Of American Eel, Anguilla Rostrata, In The Potomac River (Spring 2014), Troy D. Tuckey, Mary C. Fabrizio Sep 2014

Evaluating Recruitment Of American Eel, Anguilla Rostrata, In The Potomac River (Spring 2014), Troy D. Tuckey, Mary C. Fabrizio

Reports

The Atlantic States Marine Fisheries Commission (ASMFC) adopted the Interstate Fishery Management Plan (FMP) for the American Eel in November 1999. The FMP focuses on increasing coastal states’ efforts to collect American Eel data through both fishery‐dependent and fishery‐independent studies. Consequently, member jurisdictions agreed to implement an annual survey for young‐of‐year (YOY) American eels. The survey is intended to “…characterize trends in annual recruitment of the YOY eels over time [to produce a] qualitative appraisal of the annual recruitment of American Eel to the U.S. Atlantic Coast” (ASMFC 2000). The development of these surveys began ...

Linking Structural And Functional Characteristics Of Restored Oyster Reefs : A Restoration Project In The Virginia Coast Reserve, Lisa M. Kellogg, Mark W. Luckenbach, Jeffrey C. Cornwell, Paige G. Ross, Bowdon Lusk Jun 2014

Linking Structural And Functional Characteristics Of Restored Oyster Reefs : A Restoration Project In The Virginia Coast Reserve, Lisa M. Kellogg, Mark W. Luckenbach, Jeffrey C. Cornwell, Paige G. Ross, Bowdon Lusk

Reports

Eighteen native oyster reefs (16-m2 each) were restored using six oyster densities (0, 10, 25, 50, 100 and 250 adult oysters m-2) with three replicates of each density at an intertidal site in The Nature Conservancy’s Virginia Coast Reserve. Reef construction was successful and continues to provide a range of oyster biomass densities useful for exploring relationships between oyster reef structural and functional parameters. Between April 2012 and July 2013, a science-based monitoring program explored quantitative relationships between structural and functional characteristics of these restored reefs. Structural parameters examined included oyster abundance, oyster size/biomass, surface shell volume, reef ...


A Model For Estimating The Tmdl-Related Benefits Of Oyster Reef Restoration : Harris Creek, Maryland, Usa, M. Lisa Kellogg, Mark J. Brush, Elizabeth W. North, Younjoo Lee Jun 2014

A Model For Estimating The Tmdl-Related Benefits Of Oyster Reef Restoration : Harris Creek, Maryland, Usa, M. Lisa Kellogg, Mark J. Brush, Elizabeth W. North, Younjoo Lee

Reports

A user-friendly, web-accessible model has been developed that allows restoration practitioners and resource managers to easily estimate the TMDL-related benefits of oyster reef restoration per unit area, run restoration scenarios in Harris Creek, MD to optimize restoration planning and implementation, and calculate the benefits of the chosen plan. The model is rooted in scientifically defensible data and is readily transferable to systems throughout the Chesapeake Bay and Eastern Shore. The model operates in five vertically well-mixed boxes along the main axis of the creek. Exchanges among creeks are computed using a tidal prism approach and were compared to exchanges provided ...

Virginia Game Fish Tagging Program Annual Report 2013, Susanna Musick, Lewis Gillingham

Reports

Through 2013, the Virginia Game Fish Tagging Program has maintained a 18-year database of records for tagged and recaptured fish. The program is a co- operative project of the Virginia Saltwater Fishing Tournament (under the Virginia Marine Resources Commission-VMRC) and the Virginia Institute of Marine Science (VIMS) of the College of William and Mary (under the VIMS Marine Advisory Program).


Composition, Distribution, And Dynamics Of Intertidal Epibiota On Coastal Defense Structures, Donna Marie Bilkovic, Molly Mitchell Apr 2014

Composition, Distribution, And Dynamics Of Intertidal Epibiota On Coastal Defense Structures, Donna Marie Bilkovic, Molly Mitchell

Reports

Proliferation of artificial structures to protect shorelines has introduced novel habitat to most coastal environments and fragmented natural habitats. These changes can result in disrupted connectivity, habitat homogenization, and altered estuarine landscapes, with uncertain implications for estuarine and marine faunal community structure and function. In estuaries, such as Chesapeake Bay, where soft-bottom habitat dominates and rocky shorelines are rare, the introduction of artificial rocky structure may enhance recruitment of species that are limited by the availability of suitable substrate including native and introduced species (Bilkovic & Mitchell 2013). There is a significant lack of empirical data on the types of epibiotic ...


Monitoring Relative Abundance Of American Shad In Virginia Rivers 2013 Annual Report, Eric J. Hilton, Robert Latour, Brian Watkins, Ashleigh Magee Apr 2014

Monitoring Relative Abundance Of American Shad In Virginia Rivers 2013 Annual Report, Eric J. Hilton, Robert Latour, 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 ...


Virginia Shellfish Aquaculture Situation And Outlook Report : Results Of The 2013 Virginia Shellfish Aquaculture Crop Reporting Survey, Karen Hudson, Thomas J. Murrary Apr 2014

Virginia Shellfish Aquaculture Situation And Outlook Report : Results Of The 2013 Virginia Shellfish Aquaculture Crop Reporting Survey, Karen Hudson, Thomas J. Murrary

Reports

The shellfish aquaculture industry in Virginia continues to grow, adding significant value to the state’s seafood marketplace. Today, watermen continue to harvest both hard clams and oysters from the state’s public resources, albeit at diminished rates. At the same time, Virginia’s watermen-farmers are providing growing quantities of additional quality shellfish to consumers. In recent years, folliowing the lead of the hard clam industry, a significant transition to intensive aquaculture of native oysters is underway. The once-extensive oyster planting utilizing wild seed has contracted primarily as a result of endemic oyster diseases and increasing wildlife predation of seed ...

Virginia Coastal And Ocean Resource Issues, Virginia Institute Of Marine Science Jan 2014

Virginia Coastal And Ocean Resource Issues, Virginia Institute Of Marine Science

Reports

Fisheries, aquaculture and marine recreation in Chesapeake Bay and the coastal ocean are important economic engines adding greatly to the economy of the Commonwealth of Virginia. Virginia’s commercial harvest ranks 3rd largest and 7th in total value nationwide. Research at the Virginia Institute of Marine Science (VIMS) shows that Virginia’s water-dependent resource-based industries, including commercial and recreational fisheries, shellfish aquaculture and recreational boating, annually generate $2.53 billion in sales and approximately $1.25–$1.5 billion in income, supporting over 20,000 jobs. . . .

Thin-Layer Sediment Addition Of Dredge Material For Enhancing Marsh Resilience, Virginia Institute Of Marine Science

Reports

Building marsh elevations with sediment delivered from nearby dredging projects is a potentially valuable tool for creating, restoring, and maintaining coastal marshes, and may help slow or reverse losses of wetlands due to coastal development and sea-level rise (Woodhouse et al., 1972). . . .
