Evaluating The Recruitment Of American Eel, Anguilla Rostrata, To The Potomac - Spring 2002 : February 2002 - June 2002, Hank Brooks, M. Todd Mathes, Marcel M. Montane Oct 2002

Evaluating The Recruitment Of American Eel, Anguilla Rostrata, To The Potomac - Spring 2002 : February 2002 - June 2002, Hank Brooks, M. Todd Mathes, Marcel M. Montane

Reports

Measures of juvenile recruitment success have long been recognized as valuable fisheries management tools. In Chesapeake Bay, these measures provide reliable indicators for future year class strength for blue crabs (Lipcius and Van Engel, 1990), striped bass (Goodyear, 1985), as well as several other recreationally and commercially important species (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 ...


Qpx Susceptibility In Hard Clams Varies With Geographic Origin Of Brood Stock, Lisa M. Ragone Calvo, Eugene Burreson Aug 2002

Qpx Susceptibility In Hard Clams Varies With Geographic Origin Of Brood Stock, Lisa M. Ragone Calvo, Eugene Burreson

Reports

T he results of recent investigations by VIMS and collaborating scientists in Massachusetts and New Jersey indicate that clam strains produced from brood stocks of South Carolina and Florida origin are more susceptible to QPX (Quahog Parasite Unknown) disease than clam strains originating from Virginia, New Jersey, and Massachusetts brood stocks. During a 3-year study clam strains produced at VIMS from brood stocks originating from Massachusetts, New Jersey, Virginia, South Carolina, and Florida were grown at sites in Massachusetts, New Jersey and Virginia and evaluated for survival, growth, condition and QPX disease susceptibility. The clams originating from South Carolina and ...

Status Of The Major Oyster Diseases In Virginia 2001 A Summary Of The Annual Monitoring Program, Lisa M. Ragone Calvo, Eugene M. Burreson Feb 2002

Status Of The Major Oyster Diseases In Virginia 2001 A Summary Of The Annual Monitoring Program, Lisa M. Ragone Calvo, Eugene M. Burreson

Reports

Thirty-nine oyster populations were surveyed for disease in fall 2001. Perkinsus marinus was found in all areas sampled and prevalence exceeded 90% at all but 5 sample locations. In the James River P. marinus prevalence ranged from 88-100% at Deepwater Shoal, Horsehead Rock, Point of Shoals, Wreck Shoal, Mulberry Point, Swash, Long Shoal, and Dry Shoal. A lower prevalence was observed down river at Thomas Rock, 72%, and at Nansemond Ridge, 12%. The extremely low prevalence at Nansemond Ridge is likely age and density related; the oyster population was primarily comprised of spat; few small to market oysters were present ...

Stated Preference Methods For Environmental Management : Recreational Summer Flounder Angling In The Northeastern United States, Robert L. Hicks Jan 2002

Stated Preference Methods For Environmental Management : Recreational Summer Flounder Angling In The Northeastern United States, Robert L. Hicks

Reports

Environmental managers are becoming increasingly aware that environmental policies must be crafted in a way that incorporates the human dimensions of the ecosystem. Failure to incorporate stakeholder preferences into management measures can lead to policies that fail because people’s preferences, motivations, and behavior concerning their use of the environment were not properly considered even if defensible natural science approaches were incorporated in the management decision. In this paper, we present a new method for quantifying angler preferences for fisheries management. The method, called the Stated Preference Discrete Choice Technique (SPDC) (Louviere et. al) is a particular form of conjoint ...

Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay, January 2001-December 2001 : 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 ~trfped Bass Study program. Commencing with the 1988 annual survey, support of the program has been jointly made ...


Constraints On Sustainable Marine Fisheries In The United States: A Look At The Record, J. A. Musick, J. K. Ellis Jan 2002

Constraints On Sustainable Marine Fisheries In The United States: A Look At The Record, J. A. Musick, J. K. Ellis

Reports

The factors that may constrain or contribute to sustainable marine fisheries were examined by reviewing and analyzing the current state and history of several U.S. fisheries. Among major factors under consideration are: inherent vulnerability, (vulnerability in some species is high because of low intrinsic rates of increase and/or naturally infrequent recruitment); environmental degradation (fisheries may collapse because of anthropogenic habitat destruction); availability of data, (information necessary to conduct accurate stock assessments may not be adequate for some species); quality of the scientific advice, (inappropriate models or scientifically inaccurate assessments may be used); effectiveness of management decisions, (managers may ...


Virginia Game Fish Tagging Program Annual Report 2001, John A. Lucy, C.M. Bain Iii Jan 2002

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

Reports

The Virginia Game Fish Tagging Program (VGFTP), in its seventh year during 2001, 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.
