Distribution, Growth, And Availability Of Juvenile Croaker, Micropogon Undulatus, In Virginia, Dexter S. Haven

VIMS Articles

The shore fisheries of Virginia have long produced an important part of the nation's seafood supply. The principal fishing gears, the pound net and the haul seine, take a variety of fishes, of which the most important is the croaker, Micropogon undulatus. Prior to World War II from one-quarter to one-half of the landings of food fishes in Virginia consisted of croakers, and the catch reached a maximum in 1945 when more than 55 million pounds were landed (Fig. 1). Since that time the croaker catch has decreased precipitously, and in 1952, the latest year for which records are available, …

Notes On Fungus Parasites Of Bivalve Molluscs In Chesapeake Bay, Jay D. Andrews

VIMS Articles

My hobby is collecting the mollusks of Chesapeake Bay.. Having placed a few specimens in museums, and having made a check list · (no new species yet) with appended distribution records, I found my hobby less stimulating than rily research .. , But then my research had. taken a turn which opened up new and inviting fields of discovery.

First came a devastating mortality of oysters in the Rappahannock River, for which no explanation has been found. Then Mackin et~ .. l. (']_950) discovered the fungus disease of oysters, Dermocystidium marinum ... But not until Ray (1952) developed the thioglycollate …

The Fishes Of The Tidewater Section Of The Pamunkey River, Virginia, Edward C. Raney, William H. Massman

VIMS Articles

The distribution of the fish fauna of the tidewater section of most of the rivers that flow into Chesapeake Bay is poorly known. Indeed, this is true for practically all the great rivers tributary to the Atlantic from the Hudson southward to the Savannah. The few investigations usually have concentrated on commercial species and our understanding of distribution has been inferred from the knowledge of nearby Coastal Plain streams reported in such studies as those by Hildebrand and Schroeder (1928), Fowler (1945), Raney (1950), and Massmann, Ladd, McCutcheon (1952).

In 1949 the junior author began a study of the spawning …

Range And Habitat Of The Clam Polymesoda-Caroliniana (Bosc) In Virginia (Family Cycladidae), Jay D. Andrews, Catherine Cook

VIMS Articles

The clam Polymesoda caroliniana (Bosc), which ranges north and eastward in brackish waters from Lavaca Bay, Texas,2 has not pre- viously been reported north of the Neuse River, N. C. (Van der Schalie 1933). On 7 April 1947, Richard Hoffman found several shells on the beach above Swann Point on the James River, a tributary of Chesapeake Bay (Fig. 1). On 20 April 1947, J. P. E. Morrison (personal communication) and Hoffman found living specimens in the mud and detritus around the knees of cypress trees one-half mile above Swann Point. These records are included in this paper through the …

Seasonal Patterns Of Oyster Setting In The James River And Chesapeake Bay, Jay D. Andrews

VIMS Articles

The James River seedbeds are one of the few oyster-growing areas of the world still operated successfully as a free fishery on natural oyster grounds. It is characteristic of free fisheries that much is taken out and little is put back. For some 50 years, the James River seedbeds have continuously furnished most of the seed- oysters (young oysters) for the planters of Vir- ginia. That they are still productive is strong testimony to the natural fitness of the area for oyster culture. Yet, their survival as seed grounds must be attributed in no small measure to the laws prohibiting …

Ecological And Physiological Studies Of The Effect Of Sulfate Pulp Mill Wastes On Oysters In The York River, Virginia, Paul Galtsoff, Walter Chipman Jr., James B. Engle, Howard N. Calderwood

VIMS Articles

This study of the York River and issues impacting the oyster fishery provides historical information on the river's physical and chemical conditions (temperature, salinity, dissolved oxygen, turbidity, currents, etc.) effluent observations, history and data of the oyster fishery, oyster condition, biological and pathological work and experimental studies.

The project studies were responsible for the establishment of a fisheries laboratory in Yorktown, Va.

p. 59 - "Funds for the York River investigations were made available in 1935 by a special allotment from the Public Works Administration. Continuation of the project was made possible by regular allotments by the Bureau of Fisheries …
