Vepco Surry Power Plant Study, River Biota And Phytoplankton Entrainment Sections : Progress Report July 1975, R. Jordan, R. Carpenter, C. Becker, M Ho

Reports

This report summarizes the biological data collected from January through June 1975 in the river and phytoplankton entrainment portions of the VEPCO Surry Power Plant Study. The sampling program conducted during this period in the Hog Island area of the James River consisted of an expanded version of a study initiated in May 1969 to monitor certain aquatic communities that could be affected by the operation of the power plant. The river phytoplankton, zooplankton, benthos and fouling organism communities have been included in the past and present study designs. The phytoplankton entrainment substudy was begun in April 1975 with the …

Final Report On Effects Of Low Oxygen Tensions And High Levels Of Hydrogen Sulfide On Benthic Marine Animals, Dexter S. Haven, Robert E. Bendl

Reports

This study investigated effects of low levels of dissolved oxygen (D .O.) and low levels of D.O. in combination with hydrogen sulfide (H2S) on the larvae and adults of oysters Crassostra virginica and on adults of hard clams Mercenaria mercenaria. The purpose of this study was to investigate how low D.O. and low D. O. plus H2S, which might be associated with discharges from sewerage treatment plants, could adversely influence populations of molluscs .

Reports

This annual report covers the period October, .1973 through September, 1974. It is the seventh report generated by' the project, with 3-year completion reports prepared in 1970 and 1973. The project· is continuing at VIMS and each year allows stronger conclusions to be made concerning trends in the basic population parameters studied.

The 1970-1973 completion report was widely distributed in Virginia, libraries at fishery science institutes, and throughout the National Marine Fisheries Service. The completion report analyzed data from the entire history of the project. In many cases the entire summarized data core for a particular segment was presented, e.g. …

Remote Sensing Of Submerged Aquatic Vegetation In The Lower Chesapeake Bay : Final Report To National Aeronautical And Space Administration Langley Research Center, Robert J. Orth, Hayden H. Gordon Jan 1975

Remote Sensing Of Submerged Aquatic Vegetation In The Lower Chesapeake Bay : Final Report To National Aeronautical And Space Administration Langley Research Center, Robert J. Orth, Hayden H. Gordon

Reports

Kodak's experimental water penetration film and black and white near infrared film were used to study the distribution of submerged aquatic vegetation in the lower Chesapeake Bay. The water penetration film was very useful in this study compared to the black and white N1R. Optimal results from this film were obtained with the camera aperture closed 1/2 stop from suggested settings. Detailed description of the grass beds were obtained by flying at an altitude of 5,000 feet, at low tide when wind conditions were minimal.

There was a 36% reduction in the amount of submerged aquatic vegetation in the lower …

Fine-Structure Of Minchinia Sp (Haplosporida) Sporulation In Mud Crab, Panopeus-Herbstii, Frank O. Perkins Jan 1975

Fine-Structure Of Minchinia Sp (Haplosporida) Sporulation In Mud Crab, Panopeus-Herbstii, Frank O. Perkins

VIMS Articles

Morphogenetic changes which accompany sporulation of Minchinia sp. in the mud crab (Panopeus herbstii) are described. Small (4-19 /-1m diameter) plasmodia, the precursor cells for the sporulation sequence, increase in size and numbers of nuclei per cell to form sporonts with a delimiting wall. Since widely divergent nuclear sizes (2.3-5.9 /-1m diameter) and paired small nuclei < 3 /-1m diameter) were observed in sporonts, it is suggested that karyogamy occurs followed by meiosis. Evidence for meiosis is the observation of synaptonemal-like complexes and polycomplex-like structures in sporont nuclei. Sporonts cleave into uninucleate sporoblasts following one of two pathways. In the presumably "normal" sequence, a cytoplasmic syncytium is formed followed by cleavage into uninucleate sporoblasts. In the other, sporont protoplasm is asynchronously "carved" into uni- or binucleate sporoblasts or sporoplasms as a result of delimitation at the surface and internally. Since aberrant spore formation was commonly observed in the latter type of sporont, its cleavage patterns are considered to be anomalous. A sporoplasm is then delimited in each sporoblast and spore maturation follows. Haplosporosomes were observed in plasmodia and spores, but not in intermediate cell stages. Mitotic apparati appear to be persistent through interphase in plasmodia and sporonts and consist of two spindle pole bodies connected by a bundle of micro tubules.

Two New Species Of Sciaenid Fishes (Tribe-Sciaenini) From Caribbean Sea And Adjacent Waters, Ln Chao, Rv Miller

VIMS Articles

The genus Sciaena , heretofore monotypic, is characterized by the lack of mental barbels and an elongate swimbladder with no appendages. Two new species S. trewavasae and S. bathytatos are described herein. The new species differ from S. umbra, the type species of the genus, and from one another in the following characters: S. umbra has 11 + 14 vertebrae, 15-20 gill rakers, 23-26 soft dorsal rays, 9-13 inner gill rakers; S. trewavasae has 10 + 15 vertebrae, 19-21 gill rakers, 24-26 soft dorsal rays, 13-16 inner gill rakers; S. baillylalos has 11 + 14 vertebrae, 22-27 gill rakers, 21-23 …


The Hyperparasite, Urosporidium Spisuli Sp. N. (Haplosporea), And Its Effects On The Surf Clam Industry, Frank O. Perkins, D. E. Zwerner, Robert K. Dias Jan 1975

The Hyperparasite, Urosporidium Spisuli Sp. N. (Haplosporea), And Its Effects On The Surf Clam Industry, Frank O. Perkins, D. E. Zwerner, Robert K. Dias

VIMS Articles

SSurf clams (Spisula solidissima) from along the Virginia and North Carolina coasts are infected with an immature anisakid nematode worm which does not cause economic concern until infected with the protozoan hyperparasite, Urosporidium spisuli sp. n. When the protozoan sporulates the spores give the worm a brownish-black appearance, thus making it readily visible in clam tissues. Light and electron microscope studies of the spores reveal characteristics which differentiate the protozoan from other species of Urosporidium. All spores are killed after 5 to 30 min at 100 C; therefore, the consumer would not ingest live spores when eating commercially prepared clam …
