Water Quality Trends In The Lynnhaven Bay : A Report To The Hampton Roads Water Quality Agency, Bruce J. Neilson

Reports

The Lynnhaven Bay system is perceived by many to have a high value because of its aesthetic qualities. It is an attractive body of water to live by and enjoy. Its general cleanliness and combination of broad bays and small coves make it ideal for sailing, boating and other recreational activities. Historically the Lynnhaven oyster·has been acclaimed as an epicurean delight. These positive qualities and proximity to more urbanized areas have attracted many to live either on its shore or within the basin. What was almost entirely rural is becoming more and more urbanized. The urbanization has been underway for …

Nansemond River, Study Of Leased Oyster Grounds In The Vicinity Of The Mills E. Godwin Jr. Bridge (After Construction), Paul C. Kendall, Dexter S. Haven, James R. Whitcomb

Reports

Leased grounds were studied in the vicinity of the newly constructed Mills E. Godwin Jr, Bridge across the Nansemond River during April and May 1982 to determine if any significant changes had occurred in oyster density or bottom topography since an earlier study made in 1979 (prior to construction).

Oyster distribution outside the right-of-way in 1982 was essentially the same as in 1979. However two dug channels were seen in shallow water in the right-of-way: one was downriver of the present bridge; the second was at or near the site of the old bridge (which has been removed).

Metal Inventory And Fate Of Suspended Sediment In Chesapeake Bay, Maynard M. Nichols, Galen Thompson, Bruce Nelson

Reports

This report aims to provide new information that meets selected objectives of the EPA-States Taxies Plan of Action: i.e. (1) to determine the state of the Bay with respect to the distribution and concentration of selected metals in suspended material and fluid mud; (2) to establish the temooral variations of sediment and metal loading: (3) to identify potential zones of metal accumulation and trace their transport routes, and (4) to provide recommendations for monitoring contaminated sediment.

Field observations provide longitudinal coverage of the Bay with transects into Baltimore Harbor and Hampton Roads. They include contrasting conditions of seasonal high-low river …

Reports

A study of leased oyster planting ground in the vicinity of the proposed Route 143 Bridge across Hampton River was made by the Virginia Institute of Marine Science in March 1982. The study was made at the request of the Virginia Department of Highways and Transportation in conjunction with Project 0143-114-102, RW-201.

The Impact Of Low Salinities On James River Oyster Populations 1979-1980, Dexter S. Haven

Reports

During the fall, winter and spring of 1979-1980 there was an extensive and prolonged mortality of the 1979 se•t of oysters in the James River, Virginia. Yearling oysters died at lesser rates, with mortalities starting in mid-winter. Small oysters showed moderate to 100% mortalities at two locations. Market-sized oysters showed the lowest mortality. Deaths were associated with prolonged periods of low salinity.

Reproduction Of Oysters In Virginia, Jay D. Andrews

Reports

The seed-oyster area is located in a low-salinity sector of the James River where seasonal riverflows and resulting salinities vary widely. Low spring salinities, usually below 10 °/oo in April or May, eliminate most predators and diseases. Prior to 1960, spatfalls were, regular and moderate in intensity each year. High quality seed oysters 2 to 3 inches in size were produced with 1000 to 2000 thick-shelled oysters per bushel for use by private-ground planters. Following the advent of M. nelson! (MSX) in Chesapeake Bay in 1959, setting declined to about one-tenth previous levels and there were spatfall failures in many …

Transport Of Bivalve Larvae In The James River, Virginia, Jay D. Andrews

Reports

The James River is the primary source of seed oysters for planting private beds in the Chesapeake Bay. A sharp decline in setting rates after 1960 accompanied cessation of oyster culture on private beds in the lower sector of the river. These broodstocks were eliminated and the beds were barren after 1960. High salinities permitted a new oyster disease caused by Minchinia nelsoni (MSX) to make planting in the lower river hazardous because of high mortalities (Andrews, 1964 and in press).

Studies of larval transport mechanisms were begun in the James River in 1950, and extensive sampling was done from …

Oyster Spatfall In Virginia Rivers: 1981 Annual Summary, Dexter S. Haven, Paul C. Kendall

Reports

The Virginia Institute of Marine Science (VIMS) conducts weekly surveys from June through early October to obtain oystet spatfall information, Spat counts are made from oyster shells strung on wire and suspended from stakes on public and private beds, The number of spat on shells are counted each week of the spawning season to determine the potential of a particular area for receiving a strike and to predict the most likely period the strikes will occur.
