Chemical And Toxicological Characterization Of The Upper York River, Virginia The Mattaponi And Pamunkey Rivers, Morris H. Roberts Jr., Mark Richards, Peter F. Delisle Dec 2004

Chemical And Toxicological Characterization Of The Upper York River, Virginia The Mattaponi And Pamunkey Rivers, Morris H. Roberts Jr., Mark Richards, Peter F. Delisle

Reports

This study describes the most extensive effort to characterize the chemistry, toxicology and community of the sediments of the Mattaponi and Pamunkey Rivers. This was accomplished using a study design modified to expand the number of stations occupied by reducing the cost of analyses by compositing replicate samples collected from each study site rather than performing toxicity tests on these samples individually. In previous studies, the variability in field replicate samples was equivalent to the variability in laboratory replicates. This design has long been used to analyze samples for various chemical contaminants as a cost savings endeavor. More ....

Status Of The Major Oyster Diseases In Virginia 2003 A Summary Of The Annual Monitoring Program, Ryan B. Carnegie, Lisa M. Ragone Calvo, Eugene M. Burreson Jun 2004

Status Of The Major Oyster Diseases In Virginia 2003 A Summary Of The Annual Monitoring Program, Ryan B. Carnegie, Lisa M. Ragone Calvo, Eugene M. Burreson

Reports

Low temperatures and salinities brought abatement in the oyster diseases caused by Perkinsus marinus (Dermo) and Haplosporidium nelsoni (MSX) for the first time since 1998. In the James River, P. marinus prevalences were the lowest they had been since 1998. In summer and fall, when P. marinus is normally most prevalent, it was found in a maximum of 72% of oysters at Wreck Shoal and in less than half the oysters at Horsehead Rock and Point of Shoals. Advanced infections were very rare. Haplosporidium nelsoni had disappeared completely from quarterly James River samples by July

Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay, January 2003-December 2003 : Annual Progress Report, Herbert M. Austin, A. Dean Estes, Donald M. Seaver, Amanda H. Hewitt

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 ofjuvenile stripedbass 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 Striped Bass Study program. Commencing with the 1988 annual survey, support of the program has been jointly made through the ...

Improving Siting And Construction : Criteria For Oyster Reef Restoration, Helen Woods, William J. Hargis Jr., Carl H. Hershner, Pam Mason

Reports

The Chesapeake Bay, named Chesepiooc, the “great shellfish bay,” by the Algonquin speaking native Americans of the region, was once one of the most productive oyster (Crassostrea virginica) producing estuaries in the world. With the advent of canning and the development of the railroad system, huge national and international markets were established for Chesapeake Bay oysters (United States Secretary of the Interior 1866,Wennerston 1981). From 1894 to 1912 annual oyster harvests in Virginia alone ranged from 5 to 7.5 million bushels (Hargis and Haven 1988). Shells from harvested oysters were not replaced on oyster grounds but sold for ...


Assessing The Economic Importance Of Commercial Fisheries In The Mid-Atlantic Region: A User's Guide To The Mid-Atlantic Input/Output Model, James E. Kirkley, Winnie Ryan, John Duberg Jan 2004

Assessing The Economic Importance Of Commercial Fisheries In The Mid-Atlantic Region: A User's Guide To The Mid-Atlantic Input/Output Model, James E. Kirkley, Winnie Ryan, John Duberg

Reports

The Mid-Atlantic input/output (I/O) model is designed to estimate the economic impacts associated with the harvesting of fish1 by commercial fishermen whose landings occur in a six-state region stretching from New York to North Carolina. These impacts are expressed in terms of employment (annual average jobs—both full and part-time jobs), labor income, and output (sales by U.S. businesses).

In addition to generating estimates of economic impacts for the Mid-Atlantic region, the model estimates these impacts for 12 subregions within this region. The subregions are defined by counties within the six-state Mid-Atlantic region. Individual states have from ...
