Oyster Spatfall In Virginia Rivers: 1989 Annual Summary, Bruce J. Barber

Reports

The Virginia Institute of Marine Science (VIMS) conducts surveys of oyster spatfall (or "setting") in Virginia waters throughout the summer reproductive period. This survey provides an estimate of the potential of a particular area for receiving a "strike 11 or set of oysters on the bottom and helps define the timing of setting events. Information obtained by this effort is valuable to the Virginia Marine Resources Commission (VMRC) for its shell repletion program, and to private oyster growers, both of whom are interested in maximizing the timing of shell planting.

Bioremediation Of Contaminated Surface Soils, J. L. Sims, R. C. Sims, J. E. Matthews

Reports

Biological remediation of soils contaminated with organic chemicals is an alternative treatment technology that can often meet the goal of achieving a permanent clean-up remedy at hazardous waste sites, as encouraged by the U.S. Environmental Protection Agency (U.S. EPA) for implementation of The Superfund Amendments and Authorization Act (SARA) of 1986. Bioremediation is consistent with the philosophical thrust of SARA, for it involves the use of naturally occurring microorganisms to degrade and/or detoxify hazardous constituents in the soil at a contaminated slip to protect public health and the environment.Bioremediation of contaminated soils, including applications and limitations, has been addressed.

Geotechnical Evaluation Of Sand Resources On The Inner Shelf Of Southern Virginia : Final Report To The City Of Virginia Beach, Suzette M. Kimball, James K. Dame

Reports

The Coastal Erosion Abatement Commission, in its report to the General Assembly (1979), recommended that "there is a need to locate sources of sand supplies for rebuilding public beaches." The Sand Resources Inventory, completed in 1982 by the College of William and Mary, Virginia Institute of Marine Science, was initiated in response to this directive. The Sand Resources Inventory, however, focused on the Chesapeake Bay. The City of Virginia Beach, facing a chronic need to renourish beaches facing the Atlantic Ocean, elected to develop an inventory of beach-quality sand reserves existing on the inner shelf of the Atlantic coast.

Wetlands Mitigation Evaluation Vegetation Studies : Final Report To The City Of Norfolk, Walter I. Priest Iii

Reports

Coastal wetlands in Virginia represent a finite resource which is being
subjected to ever increasing development pressures. As a means of reducing
these losses while accomodating necessary economic development, the policy
of wetlands mitigation through compensation is increasingly being utilized
by both regulatory agencies and developers. This practice generally
involves the grading of an upland area to the appropriate elevation and
planting it with wetlands vegetation to replace a mar sh being lost in
another area.

The technology to plant and grow marsh vegetation for this and other
purposes has been well demonstrated . In as few as two growing …

A Mark-Recapture Study Of Striped Bass In The James River, Virginia : Annual Report 1988, Joseph G. Loesch, Bruce W. Hill

Reports

EXECUTIVE SUMMARY

1. In the Spring 1988, 2,145 striped bass were tagged in the James River.

2. The mean size of striped bass tagged in 1988 (351.6 mm) was 117.9 mm smaller than mean size in 1987. The difference may be due to different locations and times of tagging.

3. The dominant age group in 1987 was the 1982 year class but in 1988 the dominant age group was the 1984 year class. This difference may also be accounted for by different locations and times of tagging.

4. The exodus of the mature fish out of the river after spawning …
