Assessing Larval American Shad Growth And Survival With In Situ Mesocosm Experiments In Three Differing Habitats Within A Coastal Estuary, Donna Marie Bilkovic, David Stanhope, Carl Hershner

Reports

Habitat can be defined as the place where the organism lives including all its physical, chemical and biological dimensions (Odum 1971; Hoss and Thayer 1993). These dimensions include water quality, physical structure, flow regime and biotic interaction. Essential fish habitat (EFH) is further defined as “those waters and substrate necessary to fish for spawning, breeding, feeding, or growth to maturity” (Magnuson-Stevens Act, 16 U.S.C. 1801 et seq.) With new mandates to identify and protect EFH for all species managed under fisheries management plans, evaluation of fish habitat has become a priority. The methods used to identify and define essential fish …

Evaluating The Recruitment Of American Eel, Anguilla Rostrata, To The Potomac - Spring 2002 : February 2002 - June 2002, Hank Brooks, M. Todd Mathes, Marcel M. Montane

Reports

Measures of juvenile recruitment success have long been recognized as valuable fisheries management tools. In Chesapeake Bay, these measures provide reliable indicators for future year class strength for blue crabs (Lipcius and Van Engel, 1990), striped bass (Goodyear, 1985), as well as several other recreationally and commercially important species (Geer and Austin, 1999).

The American Eel, Anguilla rostrata, is a valuable commercial species along the entire Atlantic coast from New Brunswick to Florida. Landings along the U.S. Atlantic coast have varied from 290 MT in 1962 to a high of 1600 MT in 1975 (NMFS, 1999). In recent years, harvests …

Mycobacteriosis In Striped Bass Of The Chesapeake Bay: Expansion Of Studies Emphasizing Cultural And Rapid Molecular Diagnostic Methods To Evaluate Disease Prevalence: A Final Report, Ilsa Kaattari, Martha Rhodes Rhodes, Howard Kator

Reports

During 1997-99, the Aquatic Animal Disease Diagnostic Laboratory (AADDL) at the Virginia Institute of Marine Science (VIMS) investigated and documented an epizootic of disease in wild striped bass, Morone saxatilis, from many portions of the lower Chesapeake Bay. Some of these fish exhibited an ulcerative dermatitis initially suspected of being caused by Pfiesteria piscicida, a dinoflagellate. Skin ulcers ranged from pinpoint, pigmented spots to large, shallow hemorrhagic (bloody) wounds. This disease was determined to be due not to Pfiesteria, but to a group of bacteria called Mycobacterium spp. This disease syndrome is referred to as mycobacteriosis. Further investigations by VIMS …

A Study Of The River Origin Of American Shad Captured In The Atlantic Ocean Intercept Fishery In Virginia : Final Report, 2001, Kristin L. Maki, John E. Olney, John M. Hoenig

Reports

The Virginia Department of Game and Inland Fisheries (VDGIF) has been releasing larval American shad into the James and York river systems since 1993 and these fish are given river-specific marks before release. Our in-river monitoring program had established that we could estimate the proportion of fish returning to spawn in the rivers that have hatchery marks. Furthermore, we were able to obtain a sample of 200 fish from the intercept fishery off Chincoteague Island, Virginia, in 2000 and screening of the otoliths by VDGIF personnel revealed the presence of one fish with a James River hatchery mark and one …

Virginia Oyster Reef Restoration Map Atlas, Marcia Berman, Sharon Killeen, Roger L. Mann, J. A. Wesson

Reports

The maps are generated to illustrate the results of the targeting effort following the protocol described above. The authors recognize this level of targeting does not preclude the need for field inspection at potential sites prior to reef construction. The atlas is comprised of a series of boxes preceded by an index locator. The scale of each box may vary. The potential restoration areas are illustrated in red. The legend reports the total acres available for restoration within the boundary of each box. At this time, the size of individual restoration sites can only be retrieved using the digital data …

Qpx Susceptibility In Hard Clams Varies With Geographic Origin Of Brood Stock, Lisa M. Ragone Calvo, Eugene Burreson

Reports

T he results of recent investigations by VIMS and collaborating scientists in Massachusetts and New Jersey indicate that clam strains produced from brood stocks of South Carolina and Florida origin are more susceptible to QPX (Quahog Parasite Unknown) disease than clam strains originating from Virginia, New Jersey, and Massachusetts brood stocks. During a 3-year study clam strains produced at VIMS from brood stocks originating from Massachusetts, New Jersey, Virginia, South Carolina, and Florida were grown at sites in Massachusetts, New Jersey and Virginia and evaluated for survival, growth, condition and QPX disease susceptibility. The clams originating from South Carolina and …

Monitoring Relative Abundance Of American Shad In Virginia’S Rivers 2001 Annual Report, John E. Olney, Kristin L. Maki

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, spawning …

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 …

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 …

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 …
