Performance Of Sills: St. Mary’S City, St. Mary’S River, Maryland, C. Scott Hardaway Jr., W. G. Reay, Jian Shen, Scott Lerberg, Donna A. Milligan, Christine A. Wilcox, Kevin P. O'Brien

Reports

Living shorelines represent a shoreline management option that combines various erosion control methodologies and/or structures while at the same time restoring or preserving natural shoreline vegetation communities. A common living shoreline design in Chesapeake Bay includes a low offshore rock sill to absorb wave energy with an emergent wetland landward of the sill to enhance erosion control, provide critical habitat, and improve water quality condition. This study is part of a larger, ongoing project to (1) evaluate erosion control effectiveness and the sustainability of offshore sill and fringing marsh design and structure, (2) evaluate ecological services (e.g., habitat value, water …

Evaluating Recruitment Of American Eel, Anguilla Rostrata, To The Potomac River (Spring 2007), Hank Brooks, Wendy A. Lowery, Aimee Halvorson, James Gartland, Marcel M. Montane

Reports

Harvests of American eel along the U.S. Atlantic Coast have declined in recent years, and similar patterns have been noted in the Canadian Maritime Provinces as well as in Europe with its congener, A. anguilla (Ciccotti et al., 4 1995). Fishery independent indices of abundance have also shown a decline in American eel populations in recent years (Richkus and Whalen, 1999; Geer, 2003; Montane and Fabrizio, 2006). Possible explanations for this decline include Gulf Stream shifts, pollution, overfishing, parasites, and barriers to fish passage (Castonguay et al., 1994; Haro et al., 2000). In addition, local factors such as unfavorable wind-driven …

Estimating Relative Abundance Of Young-Of-The-Year American Eel Anguilla Rostrata In The Virginia Tributaries Of Chesapeake Bay (Spring 2006), Marcel M. Montane, Wendy A. Lowery, Hank Brooks, Aimee D. Halvorson

Reports

The Atlantic States Marine Fisheries Commission (ASMFC) adopted the Interstate Fishery Management Plan (hereafter referred to as 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 (including Virginia) agreed to implement an annual survey for 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 …

Summary Tables: Lynnhaven River Virginia Beach, Virginia Shoreline Inventory Report, Marcia Berman, Harry Berquist, Sharon Killeen, Karinna Nunez, Tamia Rudnicky, Daniel E. Schatt, Karen Reay, David Weiss

Reports

The data contained within the Shoreline Inventory is based on a three-tiered shoreline assessment approach. The assessment characterizes conditions that are observed from a small boat navigating along the shoreline. Hand-held GPS units are used to log features. The three tiered shoreline assessment approach reports conditions in three regions: 1) the immediate riparian zone, evaluated for land use; 2) the bank, evaluated for height, stability, cover and natural protection; and 3) the shoreline, describing the presence of shoreline structures for shore protection and recreational purposes. Three GIS coverages are generated. The lynn_lubc coverage contains features related to the land use …

The Stability Of Living Shorelines - An Evaluation, Center For Coastal Resources Management, Virginia Institute Of Marine Science, Marcia Berman, Harry Berquist, Julie Herman, Karinna Nunez

Reports

This project set out to strengthen arguments that living shorelines were a viable and preferred method of erosion control along much of the Chesapeake Bay shoreline. Using statistical tests and data that describe shoreline and environmental condition along tidal shoreline, the study found that indeed marshes are frequently associated with stable shoreline and therefore recommending living shoreline treatments to manage erosion problems was a reasonable strategy that warranted strong consideration. Additional tests revealed a lower occurrence of marshes when traditional erosion control structures like bulkheads and revetments were present. This confirms these structures can permanently impact the growth of tidal …

Monitoring Relative Abundance Of American Shad In Virginia Rivers 2006 Annual Report, John E. Olney, Kristen Delano Walter

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 …

South River Shoreline Management Plan Synopsis, C. Scott Hardaway Jr.

Reports

This Shoreline Management Plan (Plan) has been developed with funding from the Keith Campbell Foundation and the Chesapeake Bay Foundation in response to the Anne Arundel County’s desire to create a comprehensive shoreline management plan for the South River coast (Figure 1).

The study area includes shorelines along the South River from Chesapeake Bay west and north to just above the Route 2 Bridge. The total shoreline assessed for the study is about 82 miles. This study makes recommendations that address shoreline erosion on an as-needed basis. The impacts of “doing nothing” to the shoreline are assessed as are various …

Assessing The Impacts Of Land Use Change On Hard Clam Aquaculture In Old Plantation Creek, Northampton County, Virginia, Matthew J. Strickler

Dissertations, Theses, and Masters Projects

One of the main threats to water quality in the Chesapeake Bay is contamination by bacterial loading from point and non-point sources. While only very high levels of fecal bacteria (greater than 200 MPN/100ml) indicate the potential of a health threat to humans from contact with water, lower concentrations (14 MPN/100 ml) make the shellfish from contaminated waters unfit for human consumption. Many nearshore areas that are vulnerable to bacterial contamination also are suitable for the propagation of shellfish, including the hard clam (Mercenaria mercenaria). This is especially true on Virginia’s Eastern Shore, where shallow, sheltered waters with optimal salinity …
