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 …

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.

The James River Public Seed Oyster Area In Virginia (A Review Of 22 Years Of Setting And Population Studies, 1946 To 1967 And Changes Caused By Minchinia Nelsoni (Msx) After 1960), 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 planterH. Following the advent of M. nelsoni (MSX) in Chesapeake Bay in 1959:, setting declined to about one-tenth previous levels and there were spatfall failures in many …

Examination Of Tidal Flats. Vol. 2 A Review Of Identified Values, R J. Orth, R. Wetzel

Reports

This report summarizes the available information from the literature concerning the physical, chemical and biological processes characteristic of the tidal flat habitat and suggests possible techniques for the evaluation of coastal wetlands types for management or scientific purposes. Companion to this volume is an evaluation methodology for assessing tidal flat ecological value.

Russian Roulette With Oysters : A Review Of Exotic Introductions And Information Needed For Planning New Ones, Jay D. Andrews

Reports

Importation and transplantation of exotic oysters has probably resulted in introduction of more marine invertebrate species than any other of man's activities. Unintentional introductions have resulted from careless movements of oysters without planning or consideration of consequences. Diseases and parasites are often unknown and oysters cannot be adequately diagnosed or inspected for problems by biologists. (...)

Submerged Aquatic Vegetation : Distribution And Abundance In The Lower Chesapeake Bay And The Interactive Effects Of Light, Epiphytes, And Grazers Final Report, Robert J. Orth, Kenneth A. Moore, Jacques Van Monfrans

Reports

This final grant report is subdivided into two major sections. the first section describes the distribution and abundance of submerged aquatic vegetation (SAV) in the lower Bay. Baseline information for SAV was collected in 1978 and supplemented with additional information from 1979. Subsequently, in 1980 and 1981, overflights were conducted of all polyhaline and mesohaline areas mapped for SAV in 1978 and photographs were taken from which aerial coverage of the vegetation was measured. The data from 1978 through 1981 were analyzed for short term changes in SAV distribution and abundance. This information was combined with historical data from six …
