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.

Treatment Of Shell Cultch With Polystream To Increase The Yield Of Seed Oysters, Crassostrea Virginica, Michael Casatagna, Dexter S. Haven, James B. Whitcomb

VIMS Articles

A commercial scale study was conducted on the Eastern Shore of Virginia during 1964, 1965 and 1966 to evaluate treatment of shell cultch with Polystream. Three intertidal reefs of the same approximate size were shelled with similar amounts of untreated shells.

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.

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 …

Comparative Strength Of The 1966 Year Class Of Striped Bass, Roccus Saxatilis (Walbaum), In Three Virginia Rivers, George G. Grant, Edwin B. Joseph

VIMS Books and Book Chapters

The age composition, as determined from scale impressions, of striped bass stocks in the James, York, and Rappahannock Rivers during the period June 1967 - March 1968 indicates a relative deficiency of the 1966 year class in the James River. Similar results are shown in samples from non-selective gear (pound nets, fyke nets), selective gear (gill nets, haul seines, hook-and-line), and routine surveys using a 30-foot semi-balloon trawl.
