Chesapeake Bay Trophic Interactions Laboratory Services (Ctils): : Project Rf 05-12, June 2003-June 2006, Final Report, Debra Parthree, Christopher F. Bonzek, Robert J. Latour
Reports
Stomach samples or whole fish were obtained from a network of up to eight participating fisheries surveys in the Chesapeake Bay area. Field supplies and sample transport were provided by CTILS. Whole fish were processed for length, weight, and sex determination. Stomachs were removed and analyzed in the laboratory and prey types determined. In support of ecosystem-based fisheries management, estimates of locationspecific diet composition were produced for each species. Comparisons of dietary habits of each species among a range of habitats in the Bay and throughout various time frames were made.

Status Of The Major Oyster Diseases In Virginia 2005 A Summary Of The Annual Monitoring Program, Ryan Carnegie, Eugene M. Burreson
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 …
Water Quality Conditions And Restoration Of Submerged Aquatic Vegetation (Sav) In The Tidal Freshwater James River 2005, Ken Moore, Betty Neikirk, Britt-Anne Anderson
Water Quality Conditions And Restoration Of Submerged Aquatic Vegetation (Sav) In The Tidal Freshwater James River 2005, Ken Moore, Betty Neikirk, Britt-Anne Anderson
Reports
In 2005, wild celery (Vallisneria americana) whole shoots, seeds and intact seed pods with seeds were transplanted into four sites in the Hopewell region of the tidal James River. The SAV transplants were sampled by the Virginia Institute of Marine Science (VIMS) for survivorship and growth at bi-weekly to monthly intervals throughout the growing season. Concurrently, water quality sampling was conducted at bi-weekly intervals throughout the year for water column nutrients, chlorophyll a, suspended solids, water transparency and other chemical and physical constituents important for SAV growth. Continuous underway sampling was also conducted along the James River tidal freshwater segments …

Report Of The Virginia Graduate Marine Science Consortium The Virginia Fishery Resource Grant Program: 2006, Virginia Sea Grant
Report Of The Virginia Graduate Marine Science Consortium The Virginia Fishery Resource Grant Program: 2006, Virginia Sea Grant
Reports
The Virginia Fishery Resource Grant Program (VFRGP) was initiated by the Virginia Legislature in 1999 to “protect and enhance the Commonwealth’s coastal fishery resource through the awarding of grants.” Since its inception, the VFRGP has been administered by the Virginia Graduate Marine Science Consortium which has established the Advisory Board described in the enabling legislation; implemented proposal solicitation, review and selection procedures that avoid conflict of interest; and awarded funds for fifty-seven (57) projects since the VFRGP was initiated, five of which were begun since January, 2006. The projects initiated in 2006 account for $130,018 of the appropriated $210,000. Program …
