Fishery Independent Standing Stock Surveys Of Oyster Populations In The Virginia Sub Estuaries Of The Chesapeake Bay And A Comparison With Continuing Estimates Obtained From Fishery Dependent Data, Roger L. Mann, James Wesson
Reports
Extensive description of the Virginia oyster resource and history of its utilization has been given by Haven, Hargis and Kendall (1981), and more recently reviewed by Hargis and Haven (1988). These contributions, among many others, describe a state of continuing decline. To facilitate resource management a fishery independent survey was proposed to and subsequently supported by the Chesapeake Bay Stock Assessment Committee in 1993. This report covers activity on that program for the period October of 1993 through September of 1994.

Estimation Of Relative Abundance Of Recreationally Important Finfish In The Virginia Portion Of Chesapeake Bay: Annual Progress Report 1993-1994, Patrick J. Geer, Herb M. Austin
Estimation Of Relative Abundance Of Recreationally Important Finfish In The Virginia Portion Of Chesapeake Bay: Annual Progress Report 1993-1994, Patrick J. Geer, Herb M. Austin
Reports
Provisional annual indices of juvenile abundance have been generated from trawl survey data for six species of key recreational importance in the Virginia portion of Chesapeake Bay (spot, croaker, weakfish, summer flounder, black sea bass and striped bass) and two species of secondary importance (scup and white perch) for the period 1988-1993. No species has shown a continuous trend during the six year period. Spot has shown the largest decline from a high geometric mean catch per trawl of 68 (1988) to a low (1992) of 2, recovering to 9. 7 in 1993. Atlantic croaker continued to decline reaching levels …

Development Of Age Determination Methods, Life History/Population Dynamics Information, And Yield-Per-Recruit Simulation Modeling To Evaluate The Potential For Growth And Recruitment Overfishing Of Atlantic Croaker, Micropogonias Undulatus, In The Chesapeake Bay, Mark Chittenden, Luiz R. Barbieri, Cynthia M. Jones
Reports
The Atlantic croaker, Micropogonias undulatus, supports large recreational fisheries in the Chesapeake Bay region, where it has historically shown large fluctuations in abundance. Although many studies have been conducted on this species in this region over the last 50 years or more, commencing at least as early as Wallace (1940), little or no information exists to support yield modeling and wise management. The present studies were undertaken to provide basic life history/population dynamics information and yield modeling needed to wisely manage this species in the Chesapeake Bay region, and to evaluate the role that fishing plays in their fluctuations. Accordingly, …

Reports
The Virginia Institute of Marine Science (VIMS) has conducted a trawl survey of the Virginia tributaries to the Chesapeake Bay dating back to 1955. Over these forty years, methods and objectives have varied according to funding sources and state and/ or federal mandates. The present thrust of the program is to provide juvenile indices of relative abundance of recreationally, commercially, and ecologically important finfish and invertebrates. In 1988, the main area of focus was as a monitoring device of the resources of the Chesapeake Bay and its tributaries, as well as a way to create juvenile indices of key target …

Juvenile Finfish And Blue Crab Stock Assessment Program Bottom Trawl Survey Annual Data Summary Report Series Volume 1986, Michael F. Land, Patrick J. Geer, Christopher F. Bonzek, Herbert M. Austin
Reports
This report summarizes data collected by the Virginia Institute of Marine Science (VIMS) monthly trawl survey cruises for January-December 1986. The trawl survey is a long term, broad scope monitoring program. Its present primary goal is to produce annual indices of juvenile (young-of-year) abundance of commercially, recreationally and ecologically important marine and estuarine finfish and crustaceans. The objective is to provide indices of sufficient accuracy and precision for both immediate resource management needs and long-term understanding of environmental influences of fishery resources. A second important product of this effort is the documentation and monitoring of habitat utilization by juveniles and …

A Profile Of The Oyster Industry Northeastern United States, Douglas Lipton, James Kirkley
Reports
This is a critical period for the future of the east coast oyster industry. This report documents the dramatic decline in industry output which has been the impetus for a publicly funded program to "revtalize" the industry. Oyster biologists argue over the severityy of the decline and the cause, and also the potential remedies. Should non-native oysters, specifically Crassostrea gigas, be introduced into the region to replace the native oyster production? Are there ways to manage around the devastating oyster diseases MSX and Dermo? Will large populations of oysters significantly improve the water quality in currentiy degraded areas?
While these …

Harvesting Efficiency And Size Selectivity Of 3.25 And 3.50 Inch Ring Sea Scallop Dredges : Final Cruise Report, William Dupaul
Reports
Sea scallop dredges constructed with 3.25 inch (82 mm) and 3.50 inch (87 mm) rings were towed side-by-side to assess differences in harvesting efficiency and size selectivity of sea scallops (Piacopecten magellanicus). One hundred tows were made within the Canadian portion of Georges Bank from the northern edge eastward and south to the southeastern pari near Corsair Canyon. Quantities of and size distribution of scallops harvested were assessed for each dredge. Data will be analyzed to assess size selectivity and technical efficiency of scallop vessels operating in both the U.S. and Canadian portion of Georges Bank and factors affecting the …

Evidence For A Relation Between A White Perch Young-Of-The-Year Index And Indices Of Later Life Stages, Thomas C. Mosca Iii, Herbert Austin, David M. Plotner
Reports
Juvenile indices are employed in fisheries management to predict the future relative abundance of harvestable adults and to monitor the success of management efforts. Frequently, regulations controlling utilization of the resource, and a lack of fishery independent abundance data, make verification of the prediction impossible. In the case of white perch (Morone americana) in Virginia, this is not so. Using the weighting system developed for a Chesapeake Bay-wide index of juvenile striped bass abundance based on summertime beach seine data collected in nursery ground waters, we developed a similar index for white perch in the Virginia portion of the Bay. …
