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).

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 …

Development Of Oyster Resources, Katherine V. Leonard

Reports

During the 3-year project period, augmentation of cultch material and transplanting of seed oysters as a means of increasing oyster production was used. Sites were selected for the planting and transplanting. These sites were evaluated based on several criteria. One of the major considerations is the relative abundance of previous spatfall or production in a given area. Several additional factors reviewed for selection included approximate date of peak setting, substrate type (muddy, sandy, rocky, etc. bottom), impact of MSX, estimate of bar potential, gross fishing efforts and salinity regimes. It is important to plant a week or two prior to …

Anadromous Fisheries Research Program, Virginia - Annual Report 1982, Joseph G. Loesch, William H. Kriete Jr.

Reports

This presentation is the third annual report for P. L. 89-304, AFC 10 project "Anadromous Fisheries Research, Virginia," for the period 1 November 1981 to 31 October 1982. The fishes of concern were the alewife (Alosa pseudoharengus), American shad (A. sapidissima), and the blueback herring (A. aestivalis).

The Alosa species were once an important component of the landings of Virginia fisheries. In the last decade, however, there has been a dramatic decrease in American shad and river herring landings. The 1981 landings of Alosa species in Virgin.ia were the lowest ever recorded. American shad and river herring are also sought …
