Oyster Diseases In Chesapeake Bay, Jay D. Andrews

VIMS Articles

Three major diseases of oysters have been monitored in Virginia estuaries for 2-3 decades. Dermocystidium marinum, causing a warm-season wasting disease, was discovered in Virginia in 1950 and continues actively to kill oysters where beds or populations are found in high salinity waters ( >15%). This disease spreads by close proximity of dying oysters to other oysters, hence each isolated bed must be sampled in early fall annually to document activity of the pathogen. Control involves avoiding infected seed oysters, cleaning beds of all oysters after harvest, and isolation of new beds. A new pathogen, Minchinia nelsoni (MSX), caused …

A Mechanical Escalator Harvester For Live Oysters And Shell, Dexter S. Haven, John P. Whitcomb, Q C. Davis

VIMS Articles

A mechanical oyster harvester was designed, constructed and tested in Chesapeake Bay,Va.,from 1972 to 1976. It couples the escalator system of a conventional Maryland soft clam dredge with a newly designed head. Revolving spring-loaded teeth attached to two drums in the head pull or rake oysters from the bottom and horizontal water jets and the action of the revolving teeth impel the oysters onto a conveyor belt which carries the oysters to the boat.

Description And Occurrence Of Vexillifer Larvae Of Echiodon (Pisces, Carapidae) In The Western North-Atlantic And Notes On Other Carapid Vexillifers, Je Olney, Df Markle

VIMS Articles

Five hundred twenty-two vexillifers of an unnamed species of the carapid genus Echiodon are reported from ichthyoplankton collections made in the Caribbean Sea, Gulf of Mexico, Middle Atlantic Bight, Sargasso Sea, and Scotian Shelf. These are compared with 36 vexi1lifers and one juvenile of the only other known western Atlantic carapine, Campus ber- I/ludensis, as well as two small unidentified western Atlantic vexillifers, and eight eastern Pacific vexillifers of E. exsiliul/l. Vexillum placement relative to anal-fin origin, myomeres, and vertebral centra appears to be a useful character for separating Echiodon vexillifers from other western Atlantic carapids. The vexillum in Echiodon …

The Use Of Sonic Gear To Chart Locations Of Natural Bars In Lower Chesapeake Bay., D. S. Haven, J. P. Whitcomb, J. M. Zeigler, W. C. Hale

VIMS Articles

An underwater microphone has been developed to detect shell material on the bottom. The system is simple to use and easily constructed. It consists of a microphone encased in a PVC tube and suspended from an A-frame which is towed over the bottom. It is being used along with other methods to chart oyster bottoms in Virginia.

The Functional Ecology Of Submerged Aquatic Vegetation In The Lower Chesapeake Bay, Richard L. Wetzel, Kenneth L. Webb, Polly A. Penhale, Robert J. Orth, Donald F. Boesch, John V. Merriner

Reports

The research program, "The Functional Ecology of Submerged Aquatic Vegetation in the Lower Chesapeake Bay" (EPA/CBP Grant No. R805974), is an integrative effort composed of seven principal investigators. The research team has worked since July 1978 at one study site, the Vaucluse Shores area, to develop and institute a coherent research program on SAV ecological relationships.

The principal studies have focused on plant productivity, metabolism and nutrient cycling, the role of resident consumers in SAV community dynamics, the role of migratory species and efforts to develop a realistic, ecosystem simulation model of SAV communities.

The preliminary results of the first …

Oyster Spatfall In Virginia Rivers: 1979 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.

The Role Of Filter-Feeding Organisms In Concentration Of Suspended Solids Containing Kepone Into Bottom Deposits, Dexter S. Haven, Reinaldo Morales-Alamo

Reports

Filter-feeding marine animals such as molluscs, tunicates and barnacles filter particles as small as 1 micron from suspension during their feeding process and void them as fecal pellets. These settle at much faster rates than their component particles. Feces or pseudofeces which settle are termed biodeposits. Eighty-two to 93 percent by volume of the particles in the biodeposits of several species of molluscs are smaller than 4 microns; the range in size of those particles is about 1 to 10 microns (Haven and Morales-Alamo, 1973).

Community Structure Of Fishes On The Continental Slope And Rise Off The Middle Atlantic Coast Of The United States, John A. Musick

Reports

Otter trawl cruises were conducted off the middle Atlantic coast of the U. S. from 1971 to 1975. More than 50,000 specimens of demersal fishes were captured during this program at depths of 75 m to 3000 m. Species assemblages were distributed along a coenocline with bathymetric areas of rapid faunal change (anantoclines) and of more gradual faunal change (aganoclines). Between 75 and 3000 m anantoclines were found at 150 to 200 m, 400 to 600 m, 900 to 1000 m, 1350 to 1500 m, and 1900 to 2100 m. Species diversity (Hl) increased between the continental shelf and slope, …

Lower Bay Zooplankton Monitoring Program : An Introduction To The Program And Results Of The Initial Survey Of March 1978, George C. Grant, John E. Olney

Reports

The zooplankton of Chesapeake Bay occurs as two definable, seasonal populations: a summer-fall community, peaking in August, and a winter-spring assemblage, peaking in February or March (Grant 1977; Jacobs 1978). A minimum of two surveys per year are therefore required for long-term assessment of these communities: March and August have been selected as sampling months. Adequate assessment of meroplankton, particularly fish eggs and larvae and the larvae of decapod crustaceans, requires sampling over the principal reproductive period of June through August (Goy 1976; Olney 1978). Surveys for these components only are to be conducted in June and July, in addition …

Reports

Sampling of the shellfish resource in the lower part of Brick Kiln (or Wythe) Creek was conducted by personnel of the Virginia Institute of Marine Science during August, October and November of 1978. Live oysters.were found in several places from the bridge downstream t9 the mouth. Observations indicate that the oyster beds here have average growth and normal rates of survival; recruitment is occurring. No other species of commercially valuable shellfish was found.

Nansemond River, Study Of Leased Oyster Grounds In The Vicinity Of The Us 17 Bridge (Before Construction), Dexter S. Haven, Paul C. Kendall

Reports

Leased oyster ground in the vicinity of the US 17 Bridge across the Nansemond River was sampled in September, October and November of 1978 and January of 1979 by the Virginia Institute of Marine Science. ·The purposes were: 1) to determine the extent of the shellfish resources on the leased areas; and 2) to estimate the value of those resoμrces occurring within the proposed right-of-way. Other than one small, isolated lump, the only place oysters were found within the area studied was on three adjacent leases of Henry Parker.
