Potential Range Of The Zebra Mussel, Dreissena Polymorpha, In And Near Virginia, Patrick Baker, Shirley Baker, Roger L. Mann Jan 1994

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 …

Reports

This report summarizes data collected during 1993 in the Virginia portion of the Chesapeake Bay. The report is composed of two parts, part one, oyster recruitment (shell string) in Virginia and part two, dredge survey of selected oyster bars in Virginia.


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 Jan 1994

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. …
