Analysis Of Historical Distribution Of Submerged Aquatic Vegetation (Sav) In The York And Rappahannock Rivers As Evidence Of Historical Water Quality Conditions, Kenneth A. Moore, David Wilcox, Britt Anderson, Robert Orth Dec 2001

Analysis Of Historical Distribution Of Submerged Aquatic Vegetation (Sav) In The York And Rappahannock Rivers As Evidence Of Historical Water Quality Conditions, Kenneth A. Moore, David Wilcox, Britt Anderson, Robert Orth

Reports

Historical black and white format photographs at scales of approximately 1:20,000, dating from 1952 to 1956 were used to delineate the maximum coverage of SAV in the study region. Coverage of photography from decades before and after this period were found to generally to be of poorer quality and show less SAV presence. Photo-interpretation of the aerial photographs was accomplished using a head-up, on-screen digitizing system at fixed image scale of 1:12,000 and followed as closely as possible the methods currently used to delineate SAV beds throughout the Chesapeake Bay as well as the delineation of ...

Estimating Relative Abundance Of Young Of Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of The Chesapeake Bay March 2000 - June 2001, Patrick J. Geer

Reports

Measures of juvenile recruitment success have long been recognized as a valuable fisheries management tool. In the Chesapeake Bay, these measures have provided reliable indicators for future year class strength for blue crabs (Lipcius and van Engel, 1990), striped bass (Goodyear, 1985), and several other recreationally important fishes (Geer and Austin, 1999).

The American eel, Anguilla rostrata, is a valuable commercial species along the entire Atlantic coast from New Brunswick to Florida. Landings along the U.S. Atlantic coast have varied from 290 MT in 1962 to a high of 1600 MT in 1975 (NMFS, 1999). In recent years there ...

Status Of The Major Oyster Diseases In Virginia 2000 A Summary Of The Annual Monitoring Program, Lisa M. Ragone Calvo, Eugene M. Burreson

Reports

As a consequence of the relatively warm temperatures, high salinities, and high oyster parasite abundances in the fall of 1999, both P. marinus and H. nelsoni were widely distributed throughout oyster populations in Virginia in 2000. Fortunately, however, we did not see severe epizootics of the diseases as observed in some areas in 1999.

Food Habits Of Large Striped Bass In The Lower Chesapeake Bay And Its Tributaries March 1997 - May 1998, Herbert M. Austin, John F. Walter Mar 2001

Food Habits Of Large Striped Bass In The Lower Chesapeake Bay And Its Tributaries March 1997 - May 1998, Herbert M. Austin, John F. Walter

Reports

Striped bass, Marone saxatilis, are dominant seasonal predators in Chesapeake Bay and support a large recreational and commercial fishery. This document presents the results of a yearlong ( 1997-1998) food habits study of large (> 450mm or 18 inches) striped bass in lower Chesapeake Bay and adjacent ocean waters. These fish comprise the coastal migratory stock and are found in greatest abundance in Chesapeake Bay during the spring and fall. Fish were obtained from a variety of commercial, recreational and fishery-independent sources and were captured by gill, fyke and pound nets as well as recreational hook and line, otter trawl and electroshocking ...


Internesting Movements Of Loggerhead (Caretta Caretta) Sea Turtles In Virginia, Usa, Katherine L. Mansfield, John A. Musick, Soraya M. Bartol Feb 2001

Internesting Movements Of Loggerhead (Caretta Caretta) Sea Turtles In Virginia, Usa, Katherine L. Mansfield, John A. Musick, Soraya M. Bartol

Reports

Virginia is the northern most nesting region regularly utilized by loggerhead sea turtles (Caretta caretta) along the eastern coast of the United States. Along the southern shoreline of Virginia, between two and ten nests have been recorded annually since 1989 within Back Bay National Wildlife Refuge and False Cape State Park. Since 1992, the Virginia Institute of Marine Science (VIMS) has attached eight satellite transmitters to nesting loggerhead sea turtles in order to monitor their interesting movements and falVwinter migrations. VIMS has tracked the same nesting loggerhead three separate times during the 1993, 1995 and 1997 nesting seasons. This turtle ...


Virginia Game Fish Tagging Program Annual Report 2000, John A. Lucy, C.M. Bain Iii Jan 2001

Virginia Game Fish Tagging Program Annual Report 2000, John A. Lucy, C.M. Bain Iii

Reports

The Virginia Game Fish Tagging Program (VGFTP), in its sixth year during 2000, systematically trains and assists anglers in tagging a select number of species important to Virginia's marine recreational fishery and maintains the resulting tagging database. A cooperative project of the Virginia Marine Resources Commission and the Virginia Institute of Marine Science (VIMS), the program is primarily funded with revenues from Virginia's saltwater recreational fishing license funds (Recreational Fishing Development Fund). In addition, support for the program is provided by Virginia's Sea Grant Marine Advisory Program at VIMS.

Assessing Essential Fish Habitat For Bluefish Pomatomus Saltatrix (Linnaeus, 1766), In Virginia's Portion Of Chesapeake Bay And Near Shore Coastal Waters, 1988-1999, Hank Brooks, Patrick J. Geer

Reports

The Magnuson - Stevens Fishery Conservation and Management Act of 1996 strengthened the ability of the ational Marine Fisheries Service and other Fisheries Management Councils to protect and conserve habitats of marine, estuarine, and anadromous fin.fish mollusks, and crustaceans. The 1996 amendments to the act require the identification and description of essential habitat for the managed species, minimization of adverse effects on essential fish habitat (EFH) caused by fishing, and encouragement toward the conservation and enhancement of essential fish habitats. "Essential fish habitat" is broadly defined to include "those waters and substrate necessary to fish for spawning breeding feeding, or ...

Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay, January 2000-December 2000 : Annual Progress Report, Herbert M. Austin, A. Dean Estes, Donald M. Seaver

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 of juvenile striped bass 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 ...

Polychaete Key For Chesapeake Bay And Coastal Virginia, Aaron Bartholomew, Virginia Institute Of Marine Science Jan 2001

Polychaete Key For Chesapeake Bay And Coastal Virginia, Aaron Bartholomew, Virginia Institute Of Marine Science

Reports

Polychaetes are a class of annelid worms, generally marine, with more than 10,000 species. Common representatives include the lugworm (Arenicola marina) and the sandworm or clam worm Nereis. Polychaetes are important members of benthic ecosystems, serving as food for other organisms and playing a key role in mixing sediments. This key is designed to help identify polychaete species in Chesapeake Bay and coastal Virginia.
