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

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, …

Juvenile Finfish And Blue Crab Stock Assessment Program Bottom Trawl Survey Annual Data Summary Report Series Volume 1988, Michael F. Land, Patrick J. Geer, Christopher F. Bonzek, Herbert M. Austin

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 …

Trends In The Distribution, Abundance, And Habitat Quality Of Submerged Aquatic Vegetation In Chesapeake Bay And Its Tidal Tributaries: 1971 To 1991, Robert J. Orth, Richard A. Batiuk, Judith F. Nowak

Reports

This report builds on two decades of aerial and ground survey SA V distribution data, as well as development of SA V habitat requirements, establishment of SAV restoration goals and targets, compilation of historical water quality data, and implementation of a baywide monitoring program. The objectives of this report are to:

• describe trends in SAV distribution and abundance in Chesapeake Bay and its tidaf tributaries from 1 971 to 1991 ;

• relate SAV distribution over time with tiered distribution restoration goals and targets;

• compare trends in SAV distribution with corresponding trends in water quality; and • correlate …

These measures of juvenile abundance are widely used as a key element in the management of the Atlantic States' coastal fishery resources. Estimates of juveniles (age-0) have been found to provide a reliable and early indicator of future year class strength. A review …

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 …

Potential Range Of The Zebra Mussel, Dreissena Polymorpha, In And Near Virginia, Patrick Baker, Shirley Baker, Roger L. Mann

Reports

This publication is devoted to predictions of the probability of invasion by the zebra mussel, Dreissena polymorpha (and the quagga mussel, Dreissena sp.) to specific bodies of water in Virginia. Probability of invasion is divided into risk and susceptibility. Risk refers to the chance, relative to other sites, that a body of water will be inoculated with Dreissena, in sufficient number to establish a population. Inoculation can occur by natural dispersal, but in the mid-Atlantic region is most likely to-occur though accidental introduction by humans, especially via boat traffic. Susceptibility of a body of water refers to the probability, based …
