Monitoring Relative Abundance Of American Shad In Virginia’S Rivers 2001 Annual Report, John E. Olney, Kristin L. Maki
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 …
Reproductive Differences Among Delmarva Grass Shrimp (Palaemonetes Pugio And P. Vulgaris) Populations, Holly H. Ganz, Robert E. Knowlton
Reproductive Differences Among Delmarva Grass Shrimp (Palaemonetes Pugio And P. Vulgaris) Populations, Holly H. Ganz, Robert E. Knowlton
Virginia Journal of Science
Populations of female grass shrimps (Palaemonetes pugio and P. vulgaris) were sampled from five coastal embayments in Delaware, Maryland, and Virginia (Delmarva) and compared with respect to reproductive and life history attributes. We observed interspecific differences in timing of reproduction, carapace length, ratio of carapace length to total body length, body weight, clutch weight, clutch size, and egg volume. Onset of reproduction in P. vulgaris lagged behind P. pugio. Although there was no difference in the relationship between clutch size and carapace length for the two species, carapace length/total body length in P. pugio was greater than …
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
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
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 …
