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.

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.

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.

Taxonomy And Distribution Of Western Atlantic Bittium (Gastropoda: Mesogastropoda), Ella May Thomson Wulff

Dissertations, Theses, and Masters Projects

The genus Bittium in the Western Atlantic was studied to determine the number and distribution of extant species. Shells of adults and juveniles collected from Brazil to Canada, including the type specimens of B. virginicum, were examined and compared on the basis of length, lengthwidth ratio and varix presence or absence. Although intergrades of B. alternatum and B. varium probably existed in the middle Chesapeake Bay, along the Atlantic shores of the Delmarva Peninsula and New Jersey, and in western Long Island Sound prior to 1940, B. alternatum is now found from Shark River, New Jersey, northward and B. varium …

Batillipes Gilmartini, A New Marine Tardigrade From A California Beach, Maxine Mcginty

VIMS Articles

Two SPECIES of marine tardigrades have been reported from the Pacific coast of North America. Schuster and Grigarick (1965) studied Echiniscoides sigismundi Schultze, 1865, from algae and barnacles. This species is thought to occur along much of the west coast. Styraconx sargassi Thulin, 1942, was reported as Bathyechiniscus tetronyx Steiner, 1926, from washings of Dictyota sp. by Mathews (1938). Although marine tardigrades are often found in association with algae and a variety of animals, they are most abundant in the interstitial spaces of sandy beaches. The apparently rich interstitial fauna of the west coast has not as yet been investigated.

Larval Development Of Bathynectes Superba (Costa) Reared In The Laboratory., Morris H. Roberts Jr.

VIMS Articles

The present study was undertaken to determine the number of larval stages in Bathynectes, and to describe each larval stage in detail based on laboratory raised specimens. Criteria for distinguishing Bathynectes from other Portunidae were sought.

Boring Mechanism Of Polydora Websteri Inhabiting Crassostrea Virginica, Sarah A. Haigler

VIMS Articles

The boring mechanisms of species of polydorid polychaetes are little understood due to lack of experimental evidence and direct observations. In thepresent studies the boring mechanism of adults and metamorphosing larvae of Polydora websteri was investigated by (1) inducing adults and larvae to settle against test substrates, (2) observing behavior in natural burrows and in "artificial blisters"composed of transparent "Pliobond" films surrounding Iceland spar substrates, (3)removing the giant setae of worms prior to tests of boring, (4) applying the giant setae to substrates, and by (5) testing for production of acid.All the layers of oyster shell, including conchiolin, were bored. …

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 …

Strobilation Of Chrysaora Quinquecirrha Polyps In The Laboratory, Harold N. Cones Jr.

VIMS Articles

The scyphistoma of Chrysaora quinquecirrha was induced to strobilate in the laboratory. Detailed description of the process is given. Just prior to strobilation, the goblet-shaped polyp undergoes color change and clefting. Each scyphistoma typically releases five ephyrae. Terminal tentacles are resorbed during strobilation and appear near its completion at the base of the strobila. Upon release, ephyrae swim to the surface and attempt to maintain their position there. Strobilation is normally complete in 20-25 hours after clefting. All stages survive well on Artemia, enchytraeids, ground ctenophores, and similar food.
