Occohannock Creek Shoreline Erosion Assessment And Living Shoreline Options Report, C. Scott Hardaway Jr., Donna A. Milligan, Kevin O'Brien, Christine Wilcox, Shoreline Studies Program, Marcia Berman, Sharon Killeen, Tami Rudnicky, Center For Coastal Resources Management

Reports

This study provides information to Occohannock Creek property owners to help them assess their shoreline stability and their options if erosion is a problem. In the past, shoreline erosion control options were typically limited to rip-rap, groins, or bulkheads. These hard structures often destroyed marsh and other habitat and may not have provided the protection desired. Other methods of erosion control now exist that have been used in a variety of conditions and evaluated for their durability and performance. The alternative techniques incorporate vegetation and are referred to as Living Shoreline designs. Conditions on Occohannock Creek make it a very …

Monitoring Relative Abundance Of American Shad In Virginia Rivers 2007 Annual Report, John E. Olney, Brian Watkins Apr 2008

Monitoring Relative Abundance Of American Shad In Virginia Rivers 2007 Annual Report, John E. Olney, Brian Watkins

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 …

New Kent County, Virginia Shoreline Inventory Report Methods And Guidelines, Marcia Berman, Harry Berquist, Sharon Killeen, Karinna Nunez, Tamia Rudnicky, Daniel E. Schatt, David Weiss, Karen Reay

Reports

The data inventory developed for the Shoreline Inventory is based on a three‑tiered shoreline assessment approach. In most cases this assessment characterizes conditions that can be observed from a small boat navigating along the shoreline. The three tiered shoreline assessment approach divides the shorezone into 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. Hand-held GPS units are used to log features observed in the field.

Reports

Human activities along our nation's coasts often lead to habitat modification, pollution, and overexploitation of living resources in coastal and estuarine waters (U.S. Commission on Ocean Policy 2004). Coastal areas are the most developed regions of the United States. In addition to recreational and leisure activities, these areas support commercial fishing, aquaculture, shipping, and defense activities. Numerous human activities can have detrimental effects on biodiversity and the provision of ecosystem services that support and sustain human populations. Given their proximity to the land and human population centers, nearshore estuarine ecosystems are especially vulnerable. Effective management can be improved with a …

Virginia Game Fish Tagging Program Annual Report 2007, John A. Lucy, Lewis Gillingham Jan 2008

Virginia Game Fish Tagging Program Annual Report 2007, John A. Lucy, Lewis Gillingham

Reports

Initiated in 1995, the Virginia Game Fish Tagging Program (VGFTP) database is comprised of tagged fish records, and corresponding recaptured fish records. These records are primarily generated through contributed efforts of a dedicated corps of trained marine anglers targeting only a select number of target species. The recaptured fish records are the result of observant individuals noticing the tags in live or freshly-boxed/shipped fish. Recapture reports originate from a mix of sources, including marine anglers, commercial fishers, workers in fish packinghouses, wholesale and retail sellers of fish, and NOAA Fisheries observers on coastal trawl boats.

Using Seeds To Propagate And Restore Vallisneria Americana Michaux (Wild Celery) In The Chesapeake Bay, Kenneth A. Moore, Jesse C. Jarvis Dec 2007

Using Seeds To Propagate And Restore Vallisneria Americana Michaux (Wild Celery) In The Chesapeake Bay, Kenneth A. Moore, Jesse C. Jarvis

Reports

Loss of submerged aquatic vegetation (SAV) has been significant in many coastal and estuarine systems such as the Chesapeake Bay where SAV die-offs have been observed in marine, brackish, and freshwater SAV communities (Orth and Moore 1983). Large-scale replanting using whole plants can be cost-prohibitive, and the use of plants taken from wild populations for propagule supply may not be possible or desirable. The use of SAV seeds for restoration has been increasingly demonstrated to be an effective method for replanting large areas of bottom, especially for marine species such as eelgrass, Zostera marina (Pickerell et al. 2005; Orth et …
