Effects Of Thermal Shock On Larvae Of The Oyster, Crassostrea Virginica (Gmelin), Robert J. Diaz

Dissertations, Theses, and Masters Projects

Larvae of the American oyster Crassostrea virginica (Gmelin) were subjected to thermal shocks of varying magnitude at different larval ages. The effects were assessed in terms of mortality, growth, and setting success. Growth of larvae acclimated at 25 C and 20% salinity was not affected by a thermal shock of 10 C or 15 C, but a 20 C thermal shock had detrimental effect on growth. Mortality of oyster larvae increased significantly following thermal chocks of 10, 15, and 20 C, and was higher for older than for younger larvae. Setting rates of the control and 10 C shocked larvae …

The Feeding Of Cornstarch To Clams And Mussels, Kathleen Rapier Harleston

Dissertations, Theses, and Masters Projects

Three concentrations of cornstarch, 0 . 6 ppm, l.l ppm, 4.0 ppm, were fed to clams and mussels during the spring, summer, and fall of 1970 . Parameters measured were shell length, shell thickness, total weight, wet meat weight, and percentage glycogen based on wet meat weight. Starch had no effect on size parameters but did influence glycogen content of meats . Mussels showed an increase of glycogen in all three seasons . Clams showed an increase only in the fall. This dissertation is from the Joint Program Degree from the College of William & Mary and University of Virginia …

Chesapeake Bay Bibliography - Volume I The James River, Susan O. Barrick, May B. Daw, Pamela S. Tennyson, Frank J. Wojcik, John J. Norcross, William J. Hargis Jr.

Reports

The Chesapeake Bay Bibliography was initiated by the Virginia Institute of Marine Science in response to growing resource management problems of the Chesapeake Bay and its tributaries. With these problems came the realization that planning and management of such a great natural resource is an overwhelming task requiring the best available information. This bibliography, therefore, was undertaken to document existing sources of information, to help identify research and data gathering needs, and to develop a comprehensive research and information services programs for individuals interested in research on, and management of the natural resources of the Chesapeake Bay region.

Hydroids And Hydromedusae Of Southern Chesapeake Bay, Dale Calder

Reports

A survey was made in southern Chesapeake Bay and its tributaries from April 1965 through March 1968 to determine the species of hydrozoans present, their seasonality and reproductive periodicities. This report discusses 43 hydroid and 27 medusa species known from the study area, of which 23 hydroids and 11 medusae have not previously been found in Chesapeake Bay. Clytia paulensis and the hydroid of Moerisia lyonsi have not been reported before in North American waters, and the hydroid of Amphinema dinema is recorded for the first time from the western Atlantic. The present records extend the northern range of one …

The Effects Of Thermal Shock And Chlorine On The Estuarine Copepod Acartia Tonsa, David Michael Dressel

Dissertations, Theses, and Masters Projects

Acute bioassays were conducted to determine the effects of thermal shock and chlorine exposure on the estuarine copepod Acartia tonsa. Laboratory conditions simulated power plant conditions using 8 C elevated temperatures and slug chlorination. A factorial design having temperatures at two levels and multiple chlorine additions, showed isolated effects of temperature and chlorine and their interaction. Adult Acartia tonsa withstood thermal shocks of 8 C above ambient summer temperatures of 20 to 25 C. No adverse effects were noted after 96 hours following an 8 ⃤ T over 5 seconds, holding at the elevated temperature for 5 minutes, and slowly …

Age, Growth, And Mortality Of The White Perch, Morone Americana (Gmelin), In The James And York Rivers, Virginia, Richard Alan St. Pierre

Dissertations, Theses, and Masters Projects

More than 750 white perch, Morone americana, were collected from each of two major tributaries of southern Chesapeake Bay to compare the age structures, growth rates, and mortality rates of the two populations.The James River is characterized by heavy domestic and industrial pollution, whereas the York River is only slightly polluted. Maximum ages determined by scale analysis were 7 and 10 years for males and females respectively in each river. Males and females from the James River were larger than those from the York up to ages IV and V, respectively. Older fish were larger in the York . Females …

Benthic Infauna Of Eelgrass, Zostera Marina, Beds, Robert Joseph Orth

Dissertations, Theses, and Masters Projects

The infauna of Zostera beds in the Chesapeake Bay-York River estuary and Chincoteague Bay was sampled in March and July using a corer. Sediments were fine sand or very fine sand. Sorting of sediments varied from poorly sorted to moderately well-sorted and was related to the density of Zostera at the respective stations. A total of 17 macroinvertebrate taxa was collected. Species abundance decreased up the estuary and there was a significant interaction in the number of species between stations and seasons. Faunal similarity of the areas sampled, as measured by three indices, indicated that the infauna of most Zostera …

The Distribution And Ecology Of The Gammaridea (Crustacea : Amphipoda) Of The Lower Chesapeake Estuaries, James Feely, Marvin L. Wass

Reports

Gammarid amphipods of three tidal rivers entering Chesapeake Bay were studied for ten months, particularly in the York River where 40 species were record during the period. Several species moved up or down the rivers with changing salinity. The more abundant species had longer breeding seasons. The number of described species from lower Chesapeake Bay is now 42 and the presence of 10 undescribed species and of several which bracket the region indicates that much remains to be learned about amphipods in the Bay. Nineteen of these have a boreal affinity and seven are limited to the Virginian subprovince. A …

Polychlorinated Biphenyls In The Elizabeth River : Final Report, Robert J. Huggett

Reports

For the past eight years, the Virginia Institute of Marine Science has been a participant of the National Pesticide Monitoring Program. Within the framework of this program, oyster samples have been collected from areas throughout the Chesapeake Bay.and analyzed for chlorinated hydrocarbon pesticides. The data from the last three years show that polychlorinated biphenyls (PCB's) are being concentrated by the eastern oyster, Crassostrea virginica. The highest concentrations found were always from one station, Hospital Point, in the Elizabeth River. Samples from this station, collected during the spring of 1971, contained residues of the PCB, Aroclor(R) 1254 of 2.8 ppm. For …

Reports

The Applied Biology Department in the VIMS Division of Applied Marine Science and Ocean Engineering conducts. weekly surveys of oyster "setting" in Virginia rivers from the end of May through early October each year. Starting at the mouth of each river and proceeding upstream to the limits of oyster setting, the collecting areas a.re established on public and private beds. Spat counts are obtained from oyster shells strung on wire and suspended from stakes. The number of spat which set in one week on the smooth side of ea.ch shell on the string are tabulated.
