Biology And Management Of River Herring And Shad In Virginia : Annual Report, Anadromous Fish Project 1975, Walter J. Hoagman, William H. Kriete

Reports

The number of pound nets and the catch of· alosines per net continued to decline in 1975. Effort by sta.ke gill nets.· increased but catch estimates declined. The James River · yielded an estimated 853,847 pounds of American shad (down 47% from 1974) with the peak of the run at the end of March. Stake gill nets landed 246,036. pounds of American shad in the York River, a decrease from 1974. Estimates of Hickory shad landings declined 83% in the York River. Pound nets in the Rappahannock River had a 75% reduction in American shad catch and stake gill net …

Biology And Management Of River Herring And Shad In Virginia : Annual Report, Anadromous Fish Project 1974, Walter J. Hoagman, John V. Merriner, William K. Kriete, Woodrow L. Wilson

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. …

An Investigation, Testing And Modifying Of Gear To Harvest Oysters And Shell : Final Contract Report For The Period 1 July, 1973 Through 30 June, 1975, Dexter S. Haven, James P. Whitcomb

Reports

During the 1974-75 contract period the hydraulic escalator was modified and tested in the York and Rappahannock Rive r s . The tests showed that the harvester was capable of raising large quantities of oysters from various types of bottoms. Moreover, these oysters were not broken or crushed, were free .of silt or grit , and t he apparatus caused only minima l damage to the bottom . The modification were made from January to April and field testing began in May 1975 in t he York and Rappahannock Rivers on public and leased bottom and on several types of …

Culture Of The Bay Scallop, Argopecten Irradians, In Virginia, Michael Castagna

VIMS Articles

In recent years there has been increased interest in the development of marine aquaculture or mariculture. Techniques for growing many traditional species. such as oysters and quahogs. have been developed, and considerable effort has also been made to test the feasibility of culturing new . less traditional species (Loosanoff and Davis,1963 : Iversen. 1968; McNeil, 1970; Price and Maurer, 1971: and Milne ,1972). This paper reviews the natural history of the bay scallop. Argopecten irradians Lamarck, and presents a review of the Virginia Institute of Marine Science's (VIMS) continuing research on this species which began in 1968.

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 …

Usable Meat Yields In The Virginia Surf Clam Fishery, Joseph G. Loesch

VIMS Articles

The weight of surf clam meat landed in Virginia is estimated by the National Marine Fisheries Service, Division of Statistics and Market News (DSMN) by multiplying bushels landed by a constant of 17 lb (7. 71 kg) of total meat per bushel. However, total meat weight includes the viscera, a portion of clam not utilized by the industry. Herein is an analysis of the yield of useable surf clam meat weight per bushel and seasonal variability in meat weight relative to seawater temperature for Virginia stocks

Inventory Of Surf Clams In Nearshore Waters From Cape Henlopen To The False Cape Area : Quarterly Progress Report, December 16, 1974 - March 15, 1975, Joseph G. Loesch

Reports

The main objectives of the study are to estimate distribution, relative abundance and recruitment of surf clams along the Delmarva Peninsula and in areas of intense harvesting off the Virginia coast. The project is a joint undertaking by the National :Larine Fisheries Service (NM.FS), and the Virginia Institute of Marine Science (VIMS). Herein-after it is associated with the latter Institution to avoid confusion with an NMFS surf clam cruise in Virginia and Nor h Carolina coastal waters in Augus t, 1974.

This report briefly summaries previous data and describes the survey for 22 October 1974. We have submitted reports to the Commission on the status of these plantings in April, 1974, and again in August, 1974. These data will not be repeated in detail, but pertinent aspects will be reviewed.

Chesapeake Bay Bibliography - Volume Iii. Maryland Waters, Jane F. Stauble, Douglas H. Wood

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.

Oyster Spatfall On Shellstrings In Virginia Rivers: 1974 Annual Summary, Dexter S. Haven, Paul C. Kendall

Reports

Oyster setting levels in m9st Virginia river systems are still far below those which commonly occurred prior to 1960. However, the 1974 season showed continuing improvement since 1972 when Tropical Storm Agnes raged through the Chesapeake Bay region, creating adverse environmental conditions which were largely responsible for the lowest setting levels on record. Data for 1973, as well as for 1971 and 1972 are included in this summary for comparison with the 1974 setting season. Setting information is obtained through surveys conducted weekly by the Virginia Institute of Marine Science (VIMS) from June through early October, with assistance of personnel …
