Habitat Requirements For The Softshell Clam, Mya Arenaria In The Chesapeake Bay, Patrick Baker, Roger L. Mann
Habitat Requirements For The Softshell Clam, Mya Arenaria In The Chesapeake Bay, Patrick Baker, Roger L. Mann
Reports
Large populations of softshell clams persist only in relatively shallow, sandy. mesohaline portions of Chesapeake Bay. These areas are mostly in Maryland, but can also occur in the Rappahannock River. Virginia. In some other portions of the bay, especially polyhaline portions. sparse populations of soft shell clams persist subtidally. Restricted populations exist intertidally.
Softshell clams grow rapidly in Chesapeake Bay, reaching commercial size in two years or less. They reproduce twice per year, in spring and fall, but probably only fall spawnings are important in maintaining population levels. Major recruitment events do not occur in most years. despite heavy annual …
Habitat Requirements For The Hard Clam, Mercenaria Mercenaria, In Chesapeake Bay, G.Curtis Roegner, Roger L. Mann
Habitat Requirements For The Hard Clam, Mercenaria Mercenaria, In Chesapeake Bay, G.Curtis Roegner, Roger L. Mann
Reports
The hard clam, Mercenaria mercenaria, is found along the eastern coast of North America from the Gulf of St. Lawrence to Texas. In Chesapeake Bay the hard clam is restricted to salinities above approximately 12 ppt. The abundances and distribution patterns of hard clams in Chesapeake Bay are based on studies performed nearly 20 years ago - a more extensive survey of hard clam resources is due. Statements concerning long term trends in populations are not feasible.
The basic anatomy of hard clams conform to that of venerid bivalves. Hard clams grow to a maximum shell length (anterior-posterior dimension) of …
Transport Of Bivalve Larvae In The James River, Virginia, Jay D. Andrews
Transport Of Bivalve Larvae In The James River, Virginia, Jay D. Andrews
Reports
The James River is the primary source of seed oysters for planting private beds in the Chesapeake Bay. A sharp decline in setting rates after 1960 accompanied cessation of oyster culture on private beds in the lower sector of the river. These broodstocks were eliminated and the beds were barren after 1960. High salinities permitted a new oyster disease caused by Minchinia nelsoni (MSX) to make planting in the lower river hazardous because of high mortalities (Andrews, 1964 and in press).
Studies of larval transport mechanisms were begun in the James River in 1950, and extensive sampling was done from …

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.

The Virginian Sea Bibliography, Thomas M. Armitage, William J. Hargis Jr.
Reports
The bibliography of the Virginian Sea is a compendium of literature and environmental data concerning the Middle Atlantic Bight region of the Western North Atlantic - or the United States east coast. The geographical coverage of this bibliography ineludes that region extending from 41° N latitude to 36° N latitude and out 200 miles from the coastal headlands. This volume represents the first step of an effort undertaken by the Virginia Institute of Marine Science to assess the present status of knowledge concerning the physical and chemical environment, biology, and fisheries of the Virginian Sea. We do not put forth …
Community Structure Of Fishes On The Continental Slope And Rise Off The Middle Atlantic Coast Of The United States, John A. Musick
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, …

Factors Associated With Accuracy In Sampling Fish Eggs And Larvae, R. R. Bowles, J. V. Merriner, G. C. Grant
Factors Associated With Accuracy In Sampling Fish Eggs And Larvae, R. R. Bowles, J. V. Merriner, G. C. Grant
Reports
Ichthyoplankton sampling gear is reviewed and evaluated with emphasis on power plant impact assessment. Effects of biotic and abiotic factors on gear accuracy are discussed. Difficulties associated with obtaining representative samples from patchy population distributions are acknowledged. A listing of commonly used sampling gear has been compiled and indexed by ecosystem. Meter nets and variations of meter nets are the most widely used gear for sampling fish eggs and larvae. Comparative gear evaluation has been performed based on information compiled in the report. Although the diversity of habitats and the great number of relatively important species makes summarization difficult, the …

Check List Of The Marine Invertebrates Of Virginia, Marvin L. Wass
Check List Of The Marine Invertebrates Of Virginia, Marvin L. Wass
Reports
This list is the third revision of a preliminary list compiled by Dr. Willis G. Hewatt in 1959. This latest revision has been shortened by the deletion of most oceanic species. Conversely, a number of estuarine species have been added through further work. Those species known from the published work of the Chesapeake Biological Laboratory, Solomons Island, Maryland, have been included.
For several groups the list should be quite complete; for others, such as the amphipods, of which there are 21 unidentified species in the VIMS collection, much taxonomic work remains. Since many species have been identified only by the …
