Rappahannock County Riparian Buffer Study, Center For Coastal Resources Management, Virginia Institute Of Marine Science
Reports
Riparian buffers (land bordering streams) are important zones for maintaining water quality and providing critical habitat. Rappahannock County has a rural landscape that presents the opportunity to record baseline conditions of riparian buffers. This study involved analyzing a small drainage area in the Upper Thornton River watershed to offer guidance on targeting riparian buffer restoration. Aerial imagery from the Virginia Base Mapping Program (VGIN, 2002) was used to create a digital data layer containing land uses and 100 ft. buffers around the streams. Buffer cover in the riparian buffers was identified as all forested, partially forested or no forest. A …

Status Of The Major Oyster Diseases In Virginia 2005 A Summary Of The Annual Monitoring Program, Ryan Carnegie, Eugene M. Burreson
Reports
More normal riverflows and salinities returned in 2005 after two very wet years. Temperatures were somewhat colder than normal during the winter, and warmer during the summer. The physical environment was generally more favorable for parasite activity, and thus brought a slight increase in prevalence and intensity of the oyster diseases caused by Perkinsus marinus (Dermo) and Haplosporidium nelsoni (MSX). Among quarterly James River Survey sites, maximum annual P. marinus prevalences returned to levels typical of the mid- 1990s, before the years of drought. P. marinus prevalence reached 92% at Wreck Shoal, 56% at Point of Shoal, 68% at Horsehead …

Monitoring Relative Abundance Of American Shad In Virginia Rivers 2005 Annual Report, John E. Olney, Kristen A. Delano
Monitoring Relative Abundance Of American Shad In Virginia Rivers 2005 Annual Report, John E. Olney, Kristen A. Delano
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 …
