Notes On Msx Resistance Of Selected Virginia Oysters, J. D. Andrews

Reports

The purpose. of these summaries is to demonstrate that a high level of genetic resistance to MSX has been acquired in lab-bred oysters in Virginia waters. The brood stocks were selected from survivors of James River seed oysters that were 90% killed in the early 1960's on private beds in Mobjack Bay. Only data from the years 1976 to 1980 are given in this summary, although comparable data have been accumulated since 1964 when laboratory· breeding began.

Notes On Oyster Diseases In Virginia, J. D. Andrews

Reports

The weather continues to occur in extremes that interfere with growth and survival of oysters in the Chesapeake Bay. First there was a very wet year in 1979 (some 63-65 inches annual rainfall), much of which occurred in excessive amounts (some 15 inches) between late September and early November. Oysters in the upper James River seed-oyster area were killed by prolonged exposure to fresh or near-fresh waters in fall and winter of 1979-80.

The Shellfish Resource In The Vicinity Of The Proposed Bridge-Tunnel For I-664, Paul C. Kendall, Dexter S. Haven

Reports

A study of the. shellfish resoμrce near the proposed site of the I-664 bridge-tunnel across Hampton Roads was conducted by the Virginia Institute of Marine Science in September 1980, Bottom samples collected with patent tongs in a corridor surrounding the proposed site indicated the following:

l. The oyster population was negligible;

2. Medium and high densities of hard clams occurred in the Northern part of the study area,. generally between Newport News Point and Middle Ground; and,

3. Density South of Middle Ground was low.

Value of all the hard clams was estimated to be slightly in excess of one …

A Study Of Some Leased Oyster Planting Grounds Adjacent To The James River Bridge, Newport News, Virginia : Conducted For The Virginia Dept. Of Highways And Transportation, Project 0017-046-102, B-605, Paul C. Kendall, Dexter S. Haven

Reports

A study of portions of two leased oyster planting grounds adjacent to the construction site of the additional lanes of the James River Bridge was conducted in October 1980. Sampling with patent tongs indicated that on one lease oysters existed in medium commercial density while the other lease had no oysters. The fathometer showed a fairly even bottom with no evidence of large holes. Audio gear was used to indicate the nature and the contents of the bottom between patent tong sampling sites.

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.

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 …

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

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.

Reports

This presentation is the first annual report for P. L. 89-304, AFC 10 project "Anadromous Fisheries Research, Virginia," for the period 1 October, 1979 to 30 September 1980.

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?
