Evaluation Of Striped Bass Stocks In Virginia, Monitoring And Tagging Studies, 1999-2003 Annual Report, 1 September 1999 - 31 October 2000, Philip W. Sadler, Robert E. Harris, John E. Olney, Robert J. Latour

Reports

To document continued compliance with Federal law, the Anadromous Fishes Program of the Virginia Institute of Marine Science (VIMS) has monitored the size and age composition, sex ratio and maturity schedules of the spawning striped bass stock in the Rappahannock River since December 1981 utilizing commercial pound nets and, since 1991, variable-mesh experimental gill nets. Spawning stock assessment was expanded to include the James River in 1994 utilizing 11 commercial fyke nets and variable-mesh experimental gill nets. The use of fyke nets was discontinued after 1997. In conjunction with the monitoring studies, tagging programs have been conducted in the James …

Virginia Marina Needs Assessment: Summary Statistics, Thomas J. Murray

Reports

In an effort to support Virginia's application for federal grant funds under the Department of Interior's "Boating Infrastructure Grant Program" (Grants), the Marina Technical Advisory Program (MT AP) at the Virginia Institute of Marine Science has undertaken assessment of the state's recreational boating infrastructure needs.1 A total of $32 million has been authorized over four years to fund this new program. It is designed to help states develop and maintain facilities for transient non-trailerable (26' and over) recreational boats. The Virginia Department of Health (VDOH) is providing overall leadership in the Boating Infrastructure Grants process supported by the The Virginia …

Changes In Bacterioplankton Metabolic Capabilities Along A Salinity Gradient In The York River Estuary, Virginia, Usa, G. E. Schultz, H. W. Ducklow

VIMS Articles

Changes in metabolic capabilities of bacterial communities along the estuarine salinity gradient may affect the extent of organic matter processing and bacterial growth and accumulation during transit through the system; As part of a larger study of estuarine microbial processes, we attempted to quantify differences in bacterial community structure using Biolog plates. Biolog GN plates (Biolog, Inc., Hayward, CA, USA) were used to determine differences in bacterioplankton community metabolic potential. Biolog GN microplates are 96-well microtiter plates in which each well contains an individual carbon source as well the redox dye tetrazolium violet. As bacteria grow and oxidize each substrate, …

Rapidan River Watershed Riparian Restoration Assessment, Friends Of The Rappahannock, Center For Coastal Resources Management, Virginia Institute Of Marine Science

Reports

A canoe based GPS survey was conducted of 111 miles of the Rapidan River and its major tributaries. The purpose of the survey was to collect the necessary baseline data to support the prioritization of stream reaches in the Rapidan River watershed for future streambank and/or riparian corridor restoration projects.

The data were post-processed and overlaid onto digital color orthophoto quarter quad images at a scale of 1: 12,000 (resolution = 2 meters). Areas with critical erosion and/or riparian restoration needs were prioritized based on the analyzed features.

Monitoring Relative Abundance Of American Shad In Virginia's Rivers Annual Report 1999, John E. Olney Sr., John M. Hoenig

Reports

A moratorium on the taking of American shad (Alosa sapidissima) in the Chesapeake Bay and its tributaries was established by the Virginia Marine Resources Commission (VMRC) beginning 1 January 1994. The prohibition applied to both recreational and commercial fishers. The moratorium was imposed at a time when commercial catch rates of American shad in Virginia's rivers were experiencing declines. Data from the commercial fishery were the best available for assessing the status of individual stocks. Catch-per-unit-effort (CPUE) data were compiled from logbooks that recorded landings by commercial fishermen using staked gill nets at various locations throughout the middle reaches of …

King And Queen County Shoreline Situation Report, Marcia Berman, Harry Berquist, Tamia Rudnicky, J. B. Glover, Sharon Dewing, Daniel E. Schatt, Kevin Skunda

Reports

The data inventory developed for the Shoreline Situation Reports are based on a three-tiered shoreline assessment approach. This assessment characterizes conditions in the shorezone observed from a small boat moving along the shoreline. Handheld GPS units record data observations in the field. The three tiered shoreline assessment approach divides the shorezone into three regions:

1. the immediate riparian zone, evaluated for land use

2. the bank, evaluated for height, stability, cover and natural protection

3. the shoreline, describing the presence of shoreline structures for shore protection and recreational purposes.

Three GIS coverages are generated from the collection technique. They can be downloaded at …

Strong Impacts Of Grazing Amphipods On The Organization Of A Benthic Community, Je Duffy, Me Hay

VIMS Articles

Large brown seaweeds dominate coastal hard substrata throughout many of the world's oceans. In coastal North Carolina, USA, this dominance by brown seaweeds is facilitated by omnivorous fishes, which feed both on red and green algae and on herbivorous amphipods that graze brown algae. When fish are removed in the field, brown seaweeds are replaced by red seaweeds, and herbivorous amphipods are more abundant. Using an array of large (similar to 4000 L) outdoor mesocosms, we tested three mechanistic hypotheses for this pattern: fish feeding facilitates brown algal dominance (1) by removing red and green algal competitors, (2) by removing …

Jackson Creek Federal Navigation Project: Stove Point Placement Area Analysis Final Draft, Donna A. Milligan, C. Scott Hardaway Jr., George R . Thomas, Rebecca C.H. Brindley

Reports

The purpose of this study is to perform a shore assessment around Jackson Creek in order to determine what processes are affecting sedimentation in the creek mouth. In addition, the placement of sandy dredge material from Jackson Creek onto Stove Point also was to be determined. The Jackson Creek-Stove Point-Stingray Point evaluation includes an assessment of shore conditions and historic shore changes as well as a wave climate and sediment transport analysis. The product of this study is a recommendation as to the location of placement of dredge spoil for beach nourishment along the Stove Point Shoreline.

Status Of The Major Oyster Diseases In Virginia 1999 A Summary Of The Annual Monitoring Program, Lisa M. Ragone Calvo, Eugene M. Burreson

Reports

As a consequence of the relatively warm temperatures and high salinities severe epizootics of both H. nelsoni and P. marinus occurred in most tributaries in VA. In the upper James River, VA prevalences and intensities of P. marinus were the highest on record. The proportion of advanced infections (moderate and heavy intensity) in October was 60% at Wreck Shoal and 48% at Horsehead Rock suggesting that significant oyster mortalities occurred in these areas. 1 Record high levels of P. marinus were also observed in Virginia's other major tributaries. Of the 39 bay oyster populations surveyed in the fall, P. marinus …

The Shoreline Management Model is a GIS spatial model that determines appropriate shoreline best management practices using available spatial data and decision tree logic. Available shoreline conditions used in the model include the presence or absence of tidal marshes, beaches, and forested riparian buffers, bank vegetation cover, bank height, wave exposure (fetch), nearshore water depth, and proximity of coastal development to the shoreline. The model output for shoreline best management practices is displayed in the locality Comprehensive Map Viewer. One GIS shapefile is developed that describes two arcs or lines representing practices in the upland area and practices at the …

Effects Of Polychlorinated Biphenyl Exposure On Development And Sexual Differentiation In Ranid Tadpoles, Mary J. Rybitski

Dissertations, Theses, and Masters Projects

The effects of AroclorRTM1242 exposure on developing amphibians were examined by exposing southern leopard frogs, Rana sphenocephala, to a contaminated diet throughout the larval period. Treatment groups consisted of an untreated control, a solvent control, 17beta-estradiol, and three PCB doses (10, 100, and 1000 mug/g). PCB accumulation and biotransformation were examined. Effects of PCB exposure on metamorphosis and sexual differentiation were assessed. PCB accumulation was not statistically different between the egg masses. Levels of PCBs in the tissues differed in a dose related manner. Within treatments, body weight appeared to be the major factor correlated with PCB concentration. Congener patterns …
