Derelict Blue Crab Trap Impacts On Marine Fisheries In The Lower York River, Virginia, Kirk J. Havens, Donna Marie Bilkovic, David Stanhope, Kory Angstadt, Carl Hershner, Center For Coastal Resources Management, Virginia Institute Of Marine Science

Reports

In Virginia, an examination of existing derelict trap data retrieved from Chesapeake Bay Multispecies Monitoring and Assessment Program (ChesMMAP) trawl surveys shows the potential effect of derelict traps on fish communities in Virginia waters (Bonzek and Latour 2005). Since 2002, ChesMMAP has attempted to sample 90 stations in the mainstem Chesapeake Bay ranging from the southern edge of the Susquehanna Flats to the Bay mouth in all depths to a minimum of 10 feet during each cruise. There are approximately 4-5 cruises per year and a large mesh bottom trawl is used to capture adult fish of a variety of …

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

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

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

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 …

Effectiveness Of The Blue Crab Spawning Sanctuary In Chesapeake Bay, Debra M. Lambert, Rom Lipcius, John M. Hoenig

Reports

The blue crab spawning stock in Chesapeake Bay sustained a severe and persistent decline beginning in 1992. As part of the effort to enhance the spawning stock, the spawning sanctuary in lower Chesapeake Bay was enlarged to over 240,000 ha. This marine reserve and corridor prohibits exploitation of mature females en route to or in the spawning grounds during the summer spawning season (1 June-15 September). To assess the effectiveness of the sanctuary, we tagged terminally molted, mature females inside and outside the sanctuary during three sanctuary seasons (2002-2004). Crabs were captured throughout the Bay and its tributaries, measured, tagged, …

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 …

Abundance, Biomass And Size Structure Of Eastern Oyster And Hooked Mussel On A Modular Artificial Reef In The Rappahannock River, Chesapeake Bay, Rom Lipcius, Russell P. Burke

Reports

Restoration efforts with native Eastern oyster, Crassostrea virginica, in Chesapeake Bay have been extensive, and there has been a continuing search for reef structures that will be effective under a range of environmental conditions. We quantified population structure, density, abundance and biomass of Eastern oyster and hooked mussel, Ischadium recurvum, on a novel concrete modular reef deployed subtidally (~ 7 m depth) in the lower Rappahannock River during October, 2000. The reef provided 3-D architectural complexity, substrate stability, and extensive surface settlement area (nearly 75 m2 of reef surface over 5 m2 of river bottom). Upon deployment, the reef was …

Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay, January 2005-December 2005 : Annual Progress Report, Herbert M. Austin, Amanda H. Hewitt, Julia K. Elllis, Mary C. Fabrizio

Reports

The primary objective of the Virginia Institute of Marine Science juvenile striped bass survey is to monitor the relative annual recruitment success of juvenile striped bass in the major Virginia nursery areas of lower Chesapeake Bay. The U.S. Fish and Wildlife Service initially funded the survey from 1967 to 1973. After a hiatus ending in 1980, funds were provided by the National Marine Fisheries Service under the Emergency Striped Bass Study program. Commencing with the 1988 annual survey, the work was jointly supported by Wallop-Breaux funds (Sport Fish Restoration Act) administered through the U.S. Fish and Wildlife Service and the …
