Laboratory And Field Studies Of The Fauna Of The Upper James Estuary : Annual Report Submitted To Virginia Electric And Power Company, Virginia Institute Of Marine Science

Reports

Grab samples at 31 stations in the Hog Island region of the James River to evaluate the benthic fauna. All species of infauna taken were identified and weighed. Sediment particle size analysis was made at each station. This region is characterized by a low diversity. The dominant organism, Rangia cuneata, may occur in densities up to l,000/m2. Other organisms common to the area are Congeria leucophaeata, Scolecoleides viridis, Corophium lacustre, Leptocheirus plumulosus and Cyathura polita.

Laboratory studies werb made to determine the effects of temperature shock on oyster! larvae, Crassostrea virginica. 10° and 15° temperature shocks were used. Growth …

Bibliography Of The Monogenetic Trematode Literature Of The World, 1758 To 1969, W. J. Hargis Jr., A. R. Lawler, R. Morales-Alamo, D. E. Zwerner

Reports

In preparing this bibliography we have attempted to collect all literature references pertaining to the Monogenea. Accordingly it represents an up-to-date (through September 1969) guide to the literature of these parasites, and is of maximum scope, including not only taxonomic literature but also references to ecological and physiological studies on Monogenea as well as reports of preferred methods of treating infestations of these parasites.

Biology And Utilization Of Anadromous Alosids: Annual Progress Report (October 1, 1968 - September 30, 1969, Jackson Davis, Joseph P. Miller, J. Ernest Warriner

Reports

Estimates of average annual mortality rates were derived. from the decline in numbers of repeat river herring spawners each year. in the Rappahannock and Potomac Rivers. The 1961 year-class contributed slightly more than 6 million fish to the fishery since 1965 while the 1962 year-class contributed nearly 5 million fish. Estimates could not be made for the James and York Rivers because the catch could not be measured. Fishing effort generally declined from 1968 in all major rivers with the Potomac River exhibiting the greatest decline. The catch of river herring in 1969 was generally lower than in 1968. Shad …

A Multidisciplinary Study Of The Scyphozoan Jellyfishes Of Lower Chesapeake Bay, 1 July 1968 - 30 June 1969, Edwin B. Joseph

Reports

At the beginning of the fiscal year covered by this report the scope of the present study was restricted to an ecological consideration of the jellyfish, Chrysaora quinquecirrha. During the winter of 1968 the project proposal was amended broadly to include physiological, biochemical and developmental aspects and the taxonomic base was expanded to include the clover leaf jellyfish Aurelia aurita and the lions mane jellyfish Cyanea capillata.

It was not possible to initiate those physiological and developmental aspects that required the medusae of the two summer species until the last month covered by this report. However some activities on all …

Treatment Of Shell With Polystream To Increase Survival Of Oysters (Crassostrea Virginica) In Virginia, Dexter S. Haven, James P. Whitcomb

Reports

Survival of oysters set on shells treated with Polystream* was investigated during 1963 and 1964. Treated and control shells were held in wire bags in the high-salinity intertidal seaside area of the Eastern Shore and in the moderate-salinity subtidal areas of the lower James River. Significantly more spat survived on treated shells than on controls. Differences in survival could not be attributed to absence of drill predation on treated shell.

James River Foraminifera, Warren Norton

Reports

Foraminifera in the James River estuary were studied at the Virginia Institute of Marine Science in 1965 and 1967. The data are presented in the hope that they will be useful for analysis or comparison with other estuaries. Interpretation of the data and further details are presented in a forthcoming publication.
