Derelict Blue Crab Trap Impacts On Marine Fisheries In The Lower York River, Virginia, Kirk J. Havens, Donna Marie Bilkovic, David Stanhope, Kory Angstadt, Carl Hershner, Center For Coastal Resources Management, Virginia Institute Of Marine Science

Reports

In Virginia, an examination of existing derelict trap data retrieved from Chesapeake Bay Multispecies Monitoring and Assessment Program (ChesMMAP) trawl surveys shows the potential effect of derelict traps on fish communities in Virginia waters (Bonzek and Latour 2005). Since 2002, ChesMMAP has attempted to sample 90 stations in the mainstem Chesapeake Bay ranging from the southern edge of the Susquehanna Flats to the Bay mouth in all depths to a minimum of 10 feet during each cruise. There are approximately 4-5 cruises per year and a large mesh bottom trawl is used to capture adult fish of a variety of …

State Of Yorktown Beach 2006, Donna A. Milligan, C. Scott Hardaway Jr., Kevin O'Brien, Christine A. Wilcox

Reports

The Yorktown Public Beach is located on the south side of the York River at Yorktown,Virginia (Figure 1). Recently, it has undergone dramatic transformation with the construction of floating piers, upscale restaurants and shops, parking garage, and additional shore management structures. The main recreational beach is now about 1,600 feet in length. A new section of beach and breakwaters is located upstream of the main recreational shore; this project area is 1,500 ft long which includes property owned by the Waterman’s Museum. The middle section of the shoreline downriver of the Route 17 Coleman Bridge, where the floating piers are …

Rappahannock County Riparian Buffer Study, Center For Coastal Resources Management, Virginia Institute Of Marine Science

Reports

Riparian buffers (land bordering streams) are important zones for maintaining water quality and providing critical habitat. Rappahannock County has a rural landscape that presents the opportunity to record baseline conditions of riparian buffers. This study involved analyzing a small drainage area in the Upper Thornton River watershed to offer guidance on targeting riparian buffer restoration. Aerial imagery from the Virginia Base Mapping Program (VGIN, 2002) was used to create a digital data layer containing land uses and 100 ft. buffers around the streams. Buffer cover in the riparian buffers was identified as all forested, partially forested or no forest. A …

Seagrass Transect Data Summary And Analysis From A Six-Year Period: 1999 - 2004, Charlotte Harbor Environmental Center, Inc, Charlotte Harbor Aquatic Preserves Florida Department Of Environmental Protection

Reports

This report contains a summary and analysis of data from a seagrass transect monitoring project begun in 1998 by the Charlotte Harbor Aquatic Preserves, Florida Department of Environmental Protection. Seagrass abundance and distribution data at twenty-six locations around Upper Charlotte Harbor, Gasparilla Sound / Lemon Bay, and the Peace and Myakka Rivers have been collected annually each year since 1999 to characterize the local and regional abundance of seagrasses. The purpose of this report is to summarize the dataset, to detect changes (if any) in seagrass abundance and distribution which may have occurred over time, to suggest mechanisms that may …

Chesapeake Bay Trophic Interactions Laboratory Services (Ctils): : Project Rf 05-12, June 2003-June 2006, Final Report, Debra Parthree, Christopher F. Bonzek, Robert J. Latour

Reports

Stomach samples or whole fish were obtained from a network of up to eight participating fisheries surveys in the Chesapeake Bay area. Field supplies and sample transport were provided by CTILS. Whole fish were processed for length, weight, and sex determination. Stomachs were removed and analyzed in the laboratory and prey types determined. In support of ecosystem-based fisheries management, estimates of locationspecific diet composition were produced for each species. Comparisons of dietary habits of each species among a range of habitats in the Bay and throughout various time frames were made.

Estimating Relative Abundance Of Young Of Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of Chesapeake Bay (Spring 2005), Marcel M. Montane, Wendy A. Lowery, Hank Brooks, Aimee D. Halvorson

Reports

The Atlantic States Marine Fisheries Commission (ASMFC) adopted the Interstate Fishery Management Plan (hereafter referred to as 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 (including Virginia) agreed to implement an annual survey for 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 …

Reports

The concept of a monitoring protocol for the environmentally sound management of federal offshore borrow areas along the U.S. east and Gulf of Mexico coasts is complex. In 2001 Research Planning, Inc. et al. developed such a protocol for the Minerals Management Service (MMS).

The proposed protocol addressed six issues:

1: Bathymetric and Substrate Surveys

2: Sediment Sampling and Analysis

3: Wave Monitoring and Modeling

4: Shoreline Monitoring and Modeling

5: Benthic Communities and Their Trophic Relationships to Fish

6: Marine Mammal and Wildlife Interactions During Dredging.

The procedures, techniques, and tools advanced to examine these issues are fully appropriate …

Colonial National Historic Park Shoreline Management Plan: Phase Ii York River Shoreline And Swanns Point, James River Shoreline, C. Scott Hardaway Jr., Donna A. Milligan, Carl H. Hobbs Iii, Christine A. Wilcox

Reports

This report presents a comprehensive shoreline management plan for Colonial National Historical Park (COLO) along its York River coast. In addition, COLO property at Swanns Point on the James River was addressed (Figure 1-1). The shoreline controlled by the U.S Naval Weapons Station on the York River is included in the overall reach analyses but not in the management plan recommendations. The plan addresses the mutual desires of state and federal agencies to improve water quality and enhance wetland habitat in Chesapeake Bay while preventing the loss of significant cultural and natural resources. Shoreline processes, past, present, and future, and …

Status Of The Major Oyster Diseases In Virginia 2005 A Summary Of The Annual Monitoring Program, Ryan Carnegie, Eugene M. Burreson

Reports

More normal riverflows and salinities returned in 2005 after two very wet years. Temperatures were somewhat colder than normal during the winter, and warmer during the summer. The physical environment was generally more favorable for parasite activity, and thus brought a slight increase in prevalence and intensity of the oyster diseases caused by Perkinsus marinus (Dermo) and Haplosporidium nelsoni (MSX). Among quarterly James River Survey sites, maximum annual P. marinus prevalences returned to levels typical of the mid- 1990s, before the years of drought. P. marinus prevalence reached 92% at Wreck Shoal, 56% at Point of Shoal, 68% at Horsehead …

A Survey Of The Effectiveness Of Existing Marsh Toe Protection Structures In Virginia, Karen Duhring, Thomas A. Barnard, Center For Coastal Resources Managment, C. Scott Hardaway Jr., Shoreline Studies Program

Reports

Using tidal marshes and other vegetated treatments for upland erosion control has been an accepted practice for years, yet the scientific understanding and established guidelines for this approach are limited. This survey was conducted to evaluate the efficacy of existing marsh toe protection structures, a particular type of erosion control treatment associated with tidal marshes on Chesapeake Bay shorelines. Field evaluations were conducted at 36 sites in 6 localities on the Middle Peninsula and Northern Neck of Virginia. General dimensions of each structure were recorded and observations made of erosion evidence, structural integrity, construction access impacts, and adjacent landscape settings. …
