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 …

The Status Of Virginia's Public Oyster Resource 1993, Reinaldo Alonzo-Morales, Roger Mann

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.

Life Cycle Studies Of Perkinsus Marinus : Host Specificity : Final Report, Grant # Na16fl0399-01, Frank O. Perkins

Reports

This project represents a renewal of Grant# NA16FL0399-0l designed to further investigate the host specificity of Perkinsus marinus by surveying for its presence in molluscs obtained from Virginia's coastal and estuarine waters. As a result of that survey, determinations were made as to the host species most appropriate for use in transmission-of-infection experiments.

Evaluation Of Seismic Sources For Repelling Sea Turtles From Hopper Dredges, Virginia Institute Of Marine Science, John A. Musick, John A. Keinath, Et Al

Reports

Hopper dredges are an effective way to both widen and deepen channels to accommodate deep draft shipping traffic. These dredging operations are required to comply with the Endangered Species Act of 1973 (Dickerson et al., 1991, Studt, 1985). It has been found that sea turtles can be entrained and killed during normal dredging operations. The five species of sea turtles that occur in the southeastern united states which may be harmed by dredging operations are the loggerhead (Caretta caretta), the green (Chelonia mydas), the Kemp's ridley (Lenidochelys kemnii) , the hawksbill (Eretomochelys imbricata) , and the leatherback (Qermochelys coriacea). Because …

Chesapeake Bay Benthic Community Restoration Goals, J. Ananda Ranasinghe, Stephen B. Weisberg, Daniel M. Dauer, Linda C. Schaffner, Robert J. Diaz, Jeffrey B. Frithsen

Reports

Benthic macroinvertebrate assemblages have been an integral part of the Chesapeake Bay monitoring program since its inception due to their ecological importance and their value as biological indicators. The condition of benthic assemblages reflects an integration of temporally variable environmental conditions and the effects of multiple types of environmental stresses. As such, benthic assemblages provide a useful complement to more temporally variable chemical and water quality monitoring measures.

While assessments using benthic monitoring data have been useful for characterizing changes in environmental conditions at individual sites over time, and for relating the condition of sites to pollution loadings and sources, …
