Water Quality In A Small Tidal Creek: Parker Creek, Virginia, Carl F. Cerco, Albert Y. Kuo

Reports

Parker Creek is a branched tidal creek located on the Eastern Shore of Virginia. In its southern branch, the creek receives waste inputs from a poultry processing plant. A study has been conducted to determine the effects of these inputs and to formulate a mathematical model of the creek system suitable for water quality planning. The model and field studies show the creek may be divided into two zones, an upstream zone dominated by freshwater flows and waste inputs, and a downstream zone dominated by conditions in adjacent Metomkin Bay. In the upstream zone of the waste-receiving branch, conditions of …

Experimental Colonization Of Crude Oil Contaminated Sediments By Benthos On The Middle Atlantic Continental Shelf, Donald Boesch, Eugene Burreson, Et Al

Reports

In August 1979 six arrays of defaunated sediment were deployed at each of three sites in the Middle Atlantic Outer Continental Shelf. Three arrays at each site had Prudhoe Bay crude oil mixed with the sediment. Because of technical difficulties recovery was limited to one control and one oiled array from two sites--one near the shelf break and one in a mid-shelf swale--after 10 months in situ. Moderate to severe sediment erosion occurred in boxes recovered from the mid-shelf. Chemical analyses indicated that between 50 and 90 percent of the added oil remained in the sediments after 10 months and …

Morphology Of Udonella Caligorum Johnston, 1835, And The Position Of Udonellidae In The Systematics Of Platyhelminths, A. V. Ivanov

Reports

The platyhelminth, Udonella, lives on parasitic copepod crustaceans and, according to the present system of classification belongs to monogenetic trematodes (Monogena) among which it is usually placed in the group Monopisthocotylea (Fuhrmann, 1928; Bychowsky, 1937; Dawes, 1946; Sproston, 1946). However, the morphology of Udonella has not yet been studied thoroughly by anyone, and a number of unusual features of the structure, ontogenesis and biology of this form cause doubts with regard to its belonging to the Monogena.

Chesapeake Bay Bibliography - Volume V. Virginia And Maryland Waters, Marilyn Neff Loesch

Recreational Boating In Virginia: A Preliminary Analysis, Thomas Murray, Jon A. Lucy

Reports

Increasingly, recreational boating and its supporting industries are being affected by governmental policy and regulatory and allocation decisions. Clearly, those charged with making these decisions cannot understand the impacts of their decisions on related business, individuals, and their livelihoods without possessing some knowledge of the general linkages between boating and local economies. This initial estimate of the economic impacts of boating in Virginia is a first step in that direction. Hopefully, a better knowledge of the nature, recent growth and present magnitude of boating in the Commonwealth will insure that decisions made which influence its existence will be'based on the …

Study To Investigate Source And Transport Route Of Marine Organisms (Hydroids And Bryozoans) In Hampton Roads And Current Velocity Profiles Of The Pier 12 Area, Naval Station, Norfolk, Virginia, Robert J. Diaz, Evon P. Ruzecki

Reports

Entrainment of the hydroid (Sertularia argentea) and the fleshly bryozoan (Alcyonidium verrilli) in the sea suction of deep draft naval vessels (carriers) in the area of the Norfolk Naval station has been a recurring problem since the early 60's. These fouling organisms (the term fouling is used in this report to indicate clogging of hull bottom intake grates and cooling system condenser tube sheets and not the growth of organisms on any part of the vessel) are winter species, growing only in the fall and winter and not the summer. Unfortunately they are also the most abundant and widely distributed …

Sediment Mixing By Invertebrates As Shown By 85kr1, Dexter S. Haven, Reinaldo Morales-Alamo, John N. Krauter

Reports

In the event radionuclides are accidentally introduced into an estuary, many isotopes would become adsorbed on suspended particles of clay or silt; others would be incorporated into living cellular material (Caritt and Goodgal, 1954; Rice and Willis, 1959). Oysters and other filter feeders in these estuaries are capable of filtering from suspension large quantities of the suspended solids, as well as the larger living cellular material (Haven and Morales-Alamo, 1966a). Ingested material along with the associated radionuclides would be voided as compacted fecal strings or pellets (biodeposits). Many of these fecal pellets may be alternately suspended in the water mass …

Oyster Spatfall In Virginia Rivers: 1980 Annual Summary, Dexter S. Haven, Paul C. Kendall

Reports

The Virginia Institute of Marine Science (VIMS) conducts weekly surveys from June through early October to obtain oyster spatfall information. Spat counts are made from oyster shells strung on wire and suspended from stakes on public and private beds. The number of spat on shells are counted each week of the spawning season to determine the potential of a particular area for receiving a strike and to predict the most likely period the strikes will occur. Shells planted just before the period of maximum set have the best chance of getting a good strike.

Determination Of The Presence, Species Composition, And Relative Abundance Of Anadromous Fishes In Pohick Creek, Fairfax, Virginia, Joseph G. Loesch

Reports

The overall concern of the study was to determine if fish laddero are needed to permit upstream migration of spawning anadromous fishes beyond the sites of impoundment. Specific questions addressed were:

1. Do anadromous species presently utilize Pohick Creek?

2. If so, what species are present?

3. How far do the species migrate upstream?

4. What is the relative abundance of the species?

5. Wl1at effects will impoundments, with ~nd without fish ladders, have on the anadromous fish resource?

Summary Of Sea Turtle Research In Virginia During 1979 And 1980: Final Report For Nmfs Contract #80 Fac 00004, John A. Musick

Reports

Directed research on the status of sea turtles in Virginia has been carried out by VIMS personnel since May 1979. Our efforts in 1979 (supported in-house) primarily comprised a documentation of sea turtle mortalities in the state. This. work was expanded somewhat in 1980 thru a small Fellowship Stipend from N.M.F.S, to support the thesis work of Molly Lutcavage. In 1980 Molly analyzed the 1979 mortality data, continued to monitor strandings, and began a tagging program in cooperation with selected poundnet fishermen. Also in 1980 we began an evaluation of sea turtle nesting in Virginia with the support of another …

Ontogenesis And Phylogenetic Interrelationships Of Parasitic Flatworms, Boris E. Bychowsky

Reports

The purpose of this report is to establish relationship among individual groups of parasitic flatworms, namely, among monogenetic trematodes (Monogenea), digenetic trematodes (Digenea), tapeworms proper (Cestoda), and the so-called Cestodaria group (AMPHILINIDAE and GYROCGTYLIDAE). The attempt to establish the above-mentioned relationships is made to a variable degree for different groups. The main point of this report is the establishment of phylogenetic relationship in the Monogenea, not only for the entire group as a whole, but also for the individual families which are members of this group. We feel that another important point is our attempt at clarifying the phylogenetic position …
