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 …

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 …

Evaluating Recruitment Of American Eel, Anguilla Rostrata, To The Potomac River (Spring 2006), Marcel M. Montane, Wendy A. Lowery, Hank Brooks, Aimee D. Halvorson

Reports

Fisheries management techniques are not often applied to American eels because basic biological information is not well known. Unknown biological parameters such as variation in growth rates and length at age have complicated stock assessment and management efforts. Though American eel are not usually considered a sport fish, their ubiquity and readiness to take a bait leads them to be caught by recreational fishermen (Collette and Klein-MacPhee, 2002). Young American eel are also used as a baitfish in coastal areas (Jenkins and 4 Burkhead, 1993.) Absence of basic population dynamics data has hampered attempts at evaluation of regional exploitation rates …

Virginia Shellfish Aquaculture Situation And Outlook Report : Results Of The 2004-2006 Virginia Shellfish Aquaculture Crop Reporting Survey, Thomas J. Murray, Michael J. Oesterling

Reports

Growth of the shellfish aquaculture industry in Virginia has added significant value to the state’s seafood marketplace. Today, watermen continue to harvest both hard clams and oysters from the state’s public resources, albeit at diminished rates. At the same time, Virginia’s watermen-farmers are providing growing quantities of additional quality shellfish to consumers. Following the lead of the hard clam industry, there has been a significant transition to intensive aquaculture of native oysters in recent years. The once extensive oyster planting has disappeared primarily as a result of endemic oyster diseases and increasing wildlife predation of seed oysters. In its place …

Monitoring Relative Abundance Of American Shad In Virginia Rivers 2005 Annual Report, John E. Olney, Kristen A. Delano

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, and …

Dune Evolution Accomack County, Virginia Chesapeake Bay Shorelines, C. Scott Hardaway Jr., Donna A. Milligan, Lyle M. Varnell, Christine Wilcox, George R. Thomas

Reports

Shoreline evolution is the change in shore position through time. In fact, it is the material resistance of the coastal geologic underpinnings against the impinging hydrodynamic (and aerodynamic) forces. Along the shores of Chesapeake Bay, it is a process-response system. The processes at work include winds, waves, tides and currents, which shape and modify coastlines by eroding, transporting and depositing sediments. The shore line is commonly plotted and measured to provide a rate of change but it is as important to understand the geomorphic patterns of change. Shore analysis provides the basis to know how a particular coast has changed …

Ernesto: Anatomy Of A Storm Tide, John D. Boon

Reports

Virginia residents were warned that tropical depression ERNESTO would bring a lot of rain and consequently some flooding from runoff. Although briefly a hurricane (sustained winds greater than 74 mph) near the island of Haiti, ERNESTO spent most of its life as a tropical storm (windsgreater than 58 mph) before crossing into Virginia on September 1, 2006, as a tropical depression(winds greater than 39 mph). Little did we know that a mere tropical depression would be packing high winds and a walloping storm tide along with the rain.
