Evaluation Of Color Imagery And Direct Referencing For Mapping Submersed Aquatic Vegetation In Chesapeake Bay - Final Report, David J. Wilcox, R J. Orth, Jennifer R. Whiting, Anna K. Kenne, Amy L. Owens, Leah S. Nagy

Reports

The VIMS Annual Submersed Aquatic Vegetation (SAV) Monitoring Program has used black and white aerial photography to map SAV in Chesapeake Bay each year from 1984 to the present, with the exception of 1988. In 2008, VIMS initiated a pilot project to address two potential enhancements identified by a recent external program review: color film and direct referencing technology. Simultaneous color and black and white imagery was captured for three regions. In addition, GPS/inertial mapping unit (IMU) direct referencing data was acquired for two of the regions.

Many factors affect the success of oyster restoration efforts. This supplemental report details the VIMS effort under this NOAA-funded program to monitor some of those factors in the Great Wicomico, Rappahannock, Piankatank and Lynnhaven Rivers. Specifically, it details monitoring of (1) oyster settlement at two reefs in each of those tributaries from May to November from 2004 – 2006, along with additional widespread recruitment monitoring in the Lynnhaven River in 2005 & 2006, (2) substrate condition on the same eight reefs during spring, summer and fall of 2004 – 2006, (3) oyster abundance on Shell Bar reef in the Great …

Status Of The Major Oyster Diseases In Virginia 2006-2008 A Summary Of The Annual Oyster Disease Monitoring Program, Ryan Carnegie, Eugene M. Burreson

Reports

Fall Survey sampling revealed P. marinus levels to be generally normal to high in Virginia tributaries. By 2007 P. marinus was present on every oyster reef sampled, and by the end of the 2006-2008 period the parasite was probably causing some mortality throughout Virginia waters. Data for H. nelsoni are still incomplete for 2006/7 because of funding limitations, but in 2008 H. nelsoni was observed at 17 of 31 sampled reefs, a marked expansion in distribution since 2003/4. A significant MSX disease outbreak occurred in the Great Wicomico River in 2008, as a mild winter and a long period of …

Estimating Relative Abundance Of Young-Of-Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of Chesapeake Bay (Spring 2009), Troy D. Tuckey, Mary C. Fabrizio

Reports

The Atlantic States Marine Fisheries Commission (ASMFC) adopted the Interstate Fishery Management Plan (FMP) for the American eel in November 1999. The FMP focuses on increasing coastal states’ efforts to collect American eel data through both fishery-dependent and fishery-independent studies. Consequently, member jurisdictions agreed to implement an annual survey for young-of-year (YOY) American eels. The survey is intended to “…characterize trends in annual recruitment of the YOY eels over time [to produce a] qualitative appraisal of the annual recruitment of American eel to the U.S. Atlantic Coast” (ASMFC 2000). The development of these surveys began in 2000 with full implementation …

Water Quality Conditions And Restoration Of Submerged Aquatic Vegetation (Sav) In The Tidal Freshwater James River, 2008, Ken Moore, Betty Berry Neikirk, Erin C. Shields, David Parrish

Reports

In 2008, wild celery (Vallisneria americana), water stargrass (Heteranthera dubia) and hydrilla (Hydrilla verticilata) shoots were transplanted into shallow water sites in the Hopewell region of the tidal James River and sampled for survivorship and growth throughout the SA V growing season. Water quality sampling was conducted at bi-weekly intervals throughout the year for water column nutrients, chlorophyll a, suspended solids, water transparency and other chemical and physical constituents important for SA V growth. Continuous water quality sampling was also conducted along the James River from the mouth of the Chickahominy River to the upstream limits of tidal water at …

Ross, Mark W. Luckenbach

Reports

To the best of our knowledge there are no published data on sea duck winter habitat use in the higher salinity portion of the lower Chesapeake Bay or in adjacent coastal bays along the Atlantic margin of the Delmarva (Delaware, Maryland, Virginia) peninsula. Within these regions both SUSC and LTDU have been observed in shallow water environments (Ross, pers. obs.), yet little is known about their habitat use or feeding habits in these areas. Importantly, these two adjacent areas, which are separated by as little as 20 km, differ in several key environmental components.

In this study we documented the …

Final Report - 2008 Data Collection And Analysis In Support Of Single And Multispecies Stock Assessments In Chesapeake Bay: The Chesapeake Bay Multispecies Monitoring And Assessment Program, Christopher F. Bonzek, James Gartland, Raemarie A. Johnson, Robert J. Latour

Reports

Historically, fisheries management has been based on the results of single‐species stock assessment models that focus on the interplay between exploitation level and sustainability. There currently exists a suite of standard and accepted analytical frameworks (e.g., virtual population analysis (VPA), biomass dynamic production modeling, delay difference models, etc.) for assessing the stocks, projecting future stock size, evaluating recovery schedules and rebuilding strategies for overfished stocks, setting allowable catches, and estimating fishing mortality or exploitation rates. A variety of methods also exist to integrate the biological system and the fisheries resource system, thereby enabling the evaluation of alternative management strategies on …

Population Assessment Of Eastern Oysters (Crassostrea Virginica) In The Seaside Coastal Bays, Paige G. Ross, Mark Luckenbach

Reports

Declines of oyster populations and commercial harvest from the Virginia seaside coastal bays have followed similar patterns, though not as severe, as those in Chesapeake Bay. High prevalence of Dermo disease (Perkinsus marinus) and MSX disease (Haplosporidium nelsoni) coupled with over harvest and habitat destruction have dramatically reduced populations. Nevertheless, there are several promising signs that significant enhancement of the population could be achieved with well conceived restoration efforts. Oyster habitat and population distribution were examined in the coastal bay system on the seaside of the Eastern Shore of Virginia. This system is composed of barrier islands, salt marshes, broad …

Repeatability Of The Enrichment Procedure For Triploid C. Ariakensis Larvae, Standish K. Allen Jr.

Reports

The principal concern for an industry based on aquaculture of triploid C. ariakensis is biosecurity, that is, the assurance against unwanted introduction of the species into the Bay during aquaculture practices. Essentially, this boils down to keeping as many diploids as possible out of the trip lo id population. We set about addressing some questions concerning reducing or eliminating the number of diploids (which on average occur at a rate of 0.1 %).

• Can diploids be purged from 4n x 2n batches by size grading?

• Is there a difference in the number of diploids eliminated between first and …

The Aquaculture Genetics And Breeding Technology's Oyster Breeding Program, Aquaculture Genetics And Breeding Technology Center, Virginia Institute Of Marine Science

Reports

The oyster breeding program in the Aquaculture Genetics and Breeding Technology Center (ABC) began in 1997 following an initiative by the Virginia General Assembly, stemming from the need to address the endemic problems of MSX- and Dermo-disease in oysters and the concomitant decline in natural fisheries . From the outset, the solution seemed to be creating domesticated lines of oysters to withstand these diseases, or to introduce new ones . Both activities have been centerpieces to ABC’s program . In so doing, the building blocks of an aquaculture industry, i .e . animals that not only survive but thrive in …
