Continuous In Vitro Culture Of The Carpet Shell Clam Tapes Decussatus Protozoan Parasite Perkinsus Atlanticus, Sm Casas, Jf La Peyre, Kimberly S. Reece, C Azevedo, A Villalba
VIMS Articles
Continuous in vitro cultures of the clam Tapes decussatus parasite Perkinsus atlanticus were established from infected gill fragments, infected haemolymph and parasite hypnospores isolated from infected gill fragments following incubation in Ray's fluid thioglycollate medium (RFTM). No continuous cultures could be initiated from P. atlanticus zoospores. Cultures initiated from hypnospores yielded the highest percentage of continuous cultures (100%, 6/6), followed by cultures initiated from gill fragments (93%, 43/46) and from haemolymph (30%, 3/10). Failures to establish continuous cultures were due to microbial contamination, The source of parasite influenced the success rate, the time taken to establish cultures and the size …

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 …

Molecular Diagnostics, Field Validation, And Phylogenetic Analysis Of Quahog Parasite Unknown (Qpx), A Pathogen Of The Hard Clam Mercenaria Mercenaria, Na Stokes, Lm Ragone Calvo, Kimberly S. Reece, Em Burreson
VIMS Articles
Quahog Parasite Unknown (QPX) is a protistan parasite that causes disease and mortality in the hard clam Mercenaria mercenaria. PCR primers and DNA oligonucleotide probes were designed and evaluated for sensitivity and specificity for the QPX organism specifically and for the phylum Labyrinthulomycota in general. The best performing QPX-specific primer pair amplified a 665 bp region of the QPX small-subunit ribosomal DNA (SSU rDNA) and detected as little as 1 fg cloned QPX SSU rDNA and 20 fg QPX genomic DNA. The primers did not amplify DNA of uninfected hard clams M. mercenaria or of the thraustochytrids Schizochytrium aggregatum, Thraustochytrium …

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 …

Two Epizootic Diseases In Chesapeake Bay Commercial Clams, Mya Arenaria And Tagelus Plebeius, Cf Dungan, Rm Hamilton, Kl Hudson, Cb Mccollough, Kimberly S. Reece
VIMS Articles
Declining Chesapeake Bay harvests of softshell clams, together with historical and emerging reports of epizootic diseases in Mya arenaria, prompted a survey in summer 2000 of the health status of selected commercial clam populations. All sampled populations (8 M. arenaria softshell clam, 2 Tagelus plebeius razor clam) were infected by Perkinsus sp. protozoans at prevalences ranging from 30 to 100% of sampled clams. Nucleotide sequences for the internal transcribed spacer (ITS) region of the rRNA gene complex were determined for clonal in vitro Perkinsus sp. isolates propagated from both M arenaria and T plebeius. Multiple polymorphic sequences were amplified from …

Study Of Perkinsosis In The Carpet Shell Clam Tapes Decussatus In Galicia (Nw Spain). I. Identification Of The Aetiological Agent And In Vitro Modulation Of Zoosporulation By Temperature And Salinity, Sm Casas, A Villalba, Kimberly S. Reece
VIMS Articles
Morphological characters of zoosporulation stages and DNA sequence of the internal transcribed spacer (ITS) region and the small subunit ribosomal RNA (SSU rRNA) gene confirmed that the aetiological agent of perkinsosis in the clam Tapes decussatus from Galicia (NW Spain) was Perkinsus atlanticus Azevedo, 1989. In vitro modulation by temperature and salinity of the zoosporulation of the parasite was studied. The optimum temperature range for zoosporulation was 19 to 28degreesC. The temperature range allowing zoosporulation in vitro was 15 to 32degreesC, which is broader than previously reported (24 to 28degreesC) for R atlanticus, and strongly suggests that zoospores can be …

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 …
