A Check List Of The Biota Of Lower Chesapeake Bay : With Inclusions From The Upper Bay And The Virginian Sea, Marvin L. Wass

Reports

The biota of Chesapeake Bay seems generally less known than that of New England and much of our West Coast. The present work attempts to mollify this discrepancy. The compilation has been revised and expanded to include plants and vertebrates. Inclusion of creatures not strictly aquatic but which may occasionally found their areas flooded by tidal waters has necessitated subjective declsions of limitation.

Includes:

• Lower Plants
• Wetland and Dune Plants
• Phylum Protozoa
• Free-living Invertebrates (except Protozoa)
• Fishes of Chesapeake Bay and the Adjacent Coastal Plain
• Herptiles of the Maryland and Virginia

The Active Pound Net Fishery In Virginia 1959-1972, Woodrow L. Wilson, Jackson W. Davis

Reports

An aerial survey of pound nets was conducted in the lower Chesapeake Bay and Virginia rivers from 1959 through 1972. The Potomac River was included from 1965 through 1972. Surveys were conducted monthly, excluding January, during this period.

The pound net is one of the most important fishing gears operated in Virginia waters. A brief description of the net is given. The number of pound nets in the fishery fluctuated from 1959 to 1966, but has been steadily declining since 1966. The term "active pound net" refers to a stand that has net hanging, and actively fishing at the time …

Biology And Utilization Of Anadromous Alosids: Annual Progress Report (October 1, 1971 - September 30, 1972), Jackson Davis, Walter J. Hoagman, John V. Merriner, Richard A. St. Pierre, Woodrow L. Wilson

Reports

Fishing effort for herring and shad has been stable for the past three years in the lower Chesapeake Bay and tributaries. River herring catch in 1972 was slightly above the 1971 landings but continued to be very low.

River herring landings in U.S. waters have declined as the c.atch has been increased by non-nationals. The catch per unit of effort has decreased from 122.5 in 1965 to 30.3 in 1972 in Virginia waters. Total mortality rates for river herring were without significant trend from 1965-1971.

Twice as much towing effort was expended in 1972 as in other years. The abundance …

Feasibility Of Increasing Striped Bass Populations By Stocking Of Underutilized Nursery Grounds : Annual Progress Report 1971-1972, John V. Merriner, Walter J. Hogman

Reports

Numerous estuaries in the lower Chesapeake Bay region and coastal Virginia possess physical, chemical and biological properties favorable· to their use as nursery grounds for striped bass. Many of them, however, are not so utilized because of the absence of associated spawning grounds. This project was designed to investigate the feasibility of stocking such underutilized nursery grounds as a management device, while monitoring population parameters such as age composition, mortality rates and relative abundance of year classes .

Economic Potential Of Clam Operation, Michael Castagna

Reports

The following estimates are based on the premise that the clam operation will be in an area where clam culture techniques will work. This means the seawater available t_o the hatchery is of suitable quality for this operation at least during the period that the clam larvae and juveniles are in that system. The food growing method (Glancy method) has been successfully used from Canada to Florida so should not be a problem.

A Study Of The Zooplankton Of Lower Chesapeake Bay : Nsf-Rann Annual Report, 1972, George C. Grant

Reports

Studies of zooplankton are necessary to any broader investigation of aquatic ecosystems. In estuaries such as the Chesapeake Bay, zooplankton function as both detritus feeders. and primary consumers of phytoplankton. Some of them, including chaetognaths, medusae and large copepods, are members of a higher trophic level. The diversity of zooplankton, especially in neiitic areas, contributes to the complexities of' such studies.

The present project was initiated wholly as a result of the interest of the National Science Foundation in Chesapeake Bay and the establishment of the Chesapeake Research Consortium. The design of the research was planned to integrate with ongoing …

The Economic History Of The Fisheries Of The Eastern Shore Of Virginia, John B. Pleasants

Reports

The economic history of the Eastern Shore has been greatly affected by both its natural characteristics and its location. Each has had both good and bad effects, with the very advantages carrying with them serious disadvantages in a bewildering juxtaposition. For instance, the sea and bay provide a boundless resource of commercially desirable species, yet lead to isolation from major markets of the area. The very isolation 0£ the Eastern Shore and its low population density lessens the possibility of pollution, thus preserving the environment on which estuarine animals are dependent. (...)

Bibliography On The Scyphozoa With Selected References On Hydrozoa And Anthozoa, Dale R. Calder, Harold N. Cones, Edwin B. Joseph

Reports

Our goal in assembling this bibliography has been to bring together literature references on all aspects of scyphozoan research. Compilation was begun in 1967 as a card file of references to publications on the Scyphozoa; selected references to hydrozoan and anthozoan studies that were considered relevant to the study of scyphozoans were included. In 1968, a major research program on the jellyfish of Chesapeake Bay was initiated at the Virginia Institute of Marine Science (VIMS) under Dr. E. B. Joseph, and work on the bibliography became an integral part of the program. In 1969 we began converting the bibliography into …

Some Sociological Perspectives On The Formation And Operation Of Commerical Fishery Cooperatives, Victor Ligouri

Reports

This report is intended to present a range of sociological perspectives: problems, questions pertaining to the formation and operation of cooperatives for and by commercial fishermen. It is a preliminary report which does not duplicate those discussions in publications specifically concerned with cooperatives (included in the selected bibliography), but rather offers themes and generalizations which I hope will prove useful, subject to criticism and discussion with staff members of VIMS. The first part of the report concerns planning the formation of a cooperative, with emphasis upon problems which have been encountered elsewhere.
