Diclidophora Nezumiae Sp. N. (Monogenea: Diclidophoridae) And Its Ecological Relationships With The Macrourid Fish Nezumia Bairdii (Goode And Bean, 1877), Thomas A. Monroe, Ronald A. Campbell, David E. Zwerner

VIMS Articles

Diclidophora nezumiae sp. n. is described from the gills of the rat-tail fish Nezumia bairdii (Goode and Bean, 1877) taken from the environs of Hudson Submarine Canyon in the northwest Atlantic. The host-parasite relationships were studied in the host population. The new species is most similar to small species of Diclidophora having short bodies that taper to maximum width at the level of the first pair of clamps. It may be differentiated from other species by the following: clamps wider than long, noticeably decreasing in size posteriorly; lamellate extension of sclerite b does not fuse with sclerite c1; unsclerotized diaphragm; …

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.

Dickey-Lincoln School Lakes Project

The overall study area encompassed the St. John River and its major tributaries; including the Little and Big Black Rivers (and their tributaries); and all lands extending 3.2 km (2 mi) beyond the maximum elevation of thv predicted impoundment of the Dickey Dam (1,560 km ). Research was concentra-ted in a portion of this area roughly bounded on the north by Chimenticook Stream, on the east by the St. John River, on the west by the United States-Canadian border, and on the south by a line drawn east-west through Seven Islands (Figure 1.0-1). Intensive marten studies were restricted to townships …

Streptococcal Infections Of Fishes, G. L. Bullock

United States Fish and Wildlife: Staff Publications

Streptococcosis is a septicemic disease that affects both freshwater and saltwater fishes; it was first reported in rainbow trout, Salmo gairdneri (Hoshino et al. 1958). Additional outbreaks have since been described in cultured golden shiners (Notemigonus crysoleucas), yellowtails (Sepiola quinqueradiata), and eels (Anguilla japonious) , and in a variety of feral saltwater fishes.

Bacterial Gill Disease Of Freshwater Fishes, S. F. Snieszko

United States Fish and Wildlife: Staff Publications

Bacterial gill disease (BGD) was first described by Davis (1926, 1927), who observed it in fry and fingerling brook trout (Salvelinus fontinalis) and rainbow trout (Salmo gairdneri) in hatcheries in Vermont. The affected trout were kept in dirt-bottom ponds and were not crowded; , daily mortalities were very low. Mortalities rapidly increased when the water temperature increased and diminished when the temperature decreased. Examination of the diseased trout revealed clubbing of gill filaments. In microscopic examination of wet mounts of the filaments" Davis found that the gill surface was covered with closely adhering strands of long, …

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

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.

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.
