Status Of The Major Oyster Diseases In Virginia 2001 A Summary Of The Annual Monitoring Program, Lisa M. Ragone Calvo, Eugene M. Burreson

Reports

Thirty-nine oyster populations were surveyed for disease in fall 2001. Perkinsus marinus was found in all areas sampled and prevalence exceeded 90% at all but 5 sample locations. In the James River P. marinus prevalence ranged from 88-100% at Deepwater Shoal, Horsehead Rock, Point of Shoals, Wreck Shoal, Mulberry Point, Swash, Long Shoal, and Dry Shoal. A lower prevalence was observed down river at Thomas Rock, 72%, and at Nansemond Ridge, 12%. The extremely low prevalence at Nansemond Ridge is likely age and density related; the oyster population was primarily comprised of spat; few small to market oysters were present …

Settlement And Survival Of The Oyster Crassostrea Virginica On Created Oyster Reef Habitats In Chesapeake Bay, Janet A. Nestlerode, Mark W. Luckenbach, Robert J. Diaz

Reports

Efforts to restore Crassostrea virginica oyster reef habitats in Chesapeake Bay typically begin with the placement of hard substrata, such as oyster shell, in the form ofthreedimensional mounds on the seabed to serve as a base for oyster recruitment and growth. A shortage of sufficient volumes of oyster shell for creating large-scale reefs has led to widespread use of other materials, such as surf clam (Spisula solidissima) shell, as a substitute for oyster shell. We monitored oyster recruitment, survival, and growth on intertidal and subtidal reefs constructed shucked oyster and surf clam shell. Results indicate that oyster settlement occurred on …

Stated Preference Methods For Environmental Management : Recreational Summer Flounder Angling In The Northeastern United States, Robert L. Hicks

Reports

Environmental managers are becoming increasingly aware that environmental policies must be crafted in a way that incorporates the human dimensions of the ecosystem. Failure to incorporate stakeholder preferences into management measures can lead to policies that fail because people’s preferences, motivations, and behavior concerning their use of the environment were not properly considered even if defensible natural science approaches were incorporated in the management decision. In this paper, we present a new method for quantifying angler preferences for fisheries management. The method, called the Stated Preference Discrete Choice Technique (SPDC) (Louviere et. al) is a particular form of conjoint analysis, …

Supplemental Data: Effects Of Physical Mixing On The Attenuation Of Polycyclic Aromatic Hydrocarbons In Estuarine Sediments., Krisa M. Arzayus, Rebecca M. Dickhut, Elizabeth A. Canuel

Reports

To examine the role of physical disturbance on the long-term preservation of polycyclic aromatic hydrocarbons (PAHs) in sediments, cores were collected from two sites removed from point sources of PAHs and representing contrasting seabed mixing regimes. Although SPAH concentrations in sediments over the past 50 years were not significantly different between the two sites, several PAH isomer ratios were significantly different (p

An Evaluation Of Interactions Between Sea Turtles And Poundnet Leaders In The Chesapeake Bay, Virginia : Final Report, Katherine L. Mansfield

Reports

Every year, thousands of sea turtles seasonally utiliz.e the Chesapeake Bay and coastal waters of Virginia as foraging grounds and developmental habitat. Sea turtles migrate north into Virginia's waters in the spring when sea temperatures warm to approximately 18° C (Coles, 1999). Since 1979, the Virginia Institute of Marine Science (VIMS) has recorded high sea turtle mortalities in the spring of the year when sea turtles first migrate into Virginia's waters. Each year, between 200 and 400 sea turtle stranding deaths are recorded within Virginia's waters. The vast majority of 1hese strandings are juvenile loggemead (Caretta caretta) and Kemp's ridley …

Virginia Game Fish Tagging Program Annual Report 2001, John A. Lucy, C.M. Bain Iii

Reports

The Virginia Game Fish Tagging Program (VGFTP), in its seventh year during 2001, systematically trains and assists anglers in tagging a select number of species important to Virginia's marine recreational fishery and maintains the resulting tagging database. A cooperative project of the Virginia Marine Resources Commission and the Virginia Institute of Marine Science (VIMS), the program is primarily funded with revenues from Virginia's saltwater recreational fishing license funds (Recreational Fishing Development Fund). In addition, support for the program is provided by Virginia's Sea Grant Marine Advisory Program at VIMS.

Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay, January 2001-December 2001 : Annual Progress Report, Herbert M. Austin, A. Dean Estes, Donald M. Seaver

Reports

The Virginia Institute of Marine Science (VIMS) has conducted a juvenile striped bass seine survey from 1967 through 1973 and from 1980 through the present. The primary objective has been the monitoring of the relative annual recruitment success of juvenile striped bass in the spawning and nursery areas of Lower Chesapeake Bay. Initially (1967-1973), the survey was funded by the U.S. Fish and Wildlife Service and when reinstated in 1980 with funding from the National Marine Fisheries Service under the Emergency ~trfped Bass Study program. Commencing with the 1988 annual survey, support of the program has been jointly made through …

Constraints On Sustainable Marine Fisheries In The United States: A Look At The Record, J. A. Musick, J. K. Ellis

Reports

The factors that may constrain or contribute to sustainable marine fisheries were examined by reviewing and analyzing the current state and history of several U.S. fisheries. Among major factors under consideration are: inherent vulnerability, (vulnerability in some species is high because of low intrinsic rates of increase and/or naturally infrequent recruitment); environmental degradation (fisheries may collapse because of anthropogenic habitat destruction); availability of data, (information necessary to conduct accurate stock assessments may not be adequate for some species); quality of the scientific advice, (inappropriate models or scientifically inaccurate assessments may be used); effectiveness of management decisions, (managers may disregard recommendations …

Control Of Mud Blister Formation In Oysters, Dennis K. Gryder

Reports

Oyster aquaculture, both commercial and recreational, continues to elicit interest, despite ongoing disease problems. One strategy for growing oysters in the presence of oyster diseases is to utilize off-bottom technology in order to "out-grow" the pathogens. It's acknowledged that oysters grown off-bottom grow quickly, but tend to have thinner, more brittle shells than those grown on-bottom. Due to the increased expenses of equipment and handling associated with growing oysters off-bottom, most oysters grown commercial in this manner are destined for the more lucrative half-shell market. In order to command higher prices, besides having a good flavor, half-shell oysters need to …
