A Study Of Oyster Ground Leases Adjacent To The James River Bridge, Newport News, Virginia, Dexter S. Haven, Paul C. Kendall, William C. Phoel

Reports

This report describes a study by the Virginia Institute of Marine Science (VIMS) on portions of the river bottom adjacent to the former site of the original James River Bridge near the Isle of Wight end. Comparisons are made of the results obtained in thi.s study (done in July and August 1977) with r2sults from a study done (in April 1976) prior to the removal of the original bridge.

The purposes of the two studies were: 1) to assess the impact (if any) of the bridge-removal activities; and 2) to quantify the magnitude of oyster stocks and their economic value.

Mercenaria Culture Using Stone Aggregate For Predator Protection, Michael Castagna, John N. Kraeuter

VIMS Articles

A low technology method utilizing hatchery-raised seed clams and field grow-out techniques is presented.This technique appears to be economically feasible and can be carried out by non-technical personnel with a minimum of training. The hatchery uses the Wells-Glancy (centrifuged, incubated seawater) method for raising food for the larval clams. The larvae set in 8 - 10 days and the seed are supplied with flowing seawater until they grow to 2 mm. The 2 mm seed were placed in nursery plots and protected from predation by a layer of gravel or crushed stone aggregate. Movement of the small clams was prevented …

A Survey In The Lafayette River For Oysters, Clams And Shell In The Vicinity Of The Colley Avenue Bridge In The Lafayette River, Norfolk, Virginia, Dexter S. Haven, Paul C. Kendall

Reports

The purposes of this study are: 1) to survey populations of oysters, Crassostrea virginica, hard clams, Mercenaria mercenaria, soft clams, Mya arenaria, and shell in the immediate vicinity of the Colley Avenue Bridge prior to its widening; 2) to evaluate the present and the possible future opportunity of the area for shellfish culture; and, 3) to estimate the value of the existing stocks of shellfish.

A Benefit-Cost Analysis Of The Virginia Oyster Subsidies : An Historical Appraisal And Proposals For The Future, Samuel H. Baker, Frederick Holladay Debrosche Harris, Carlisle E. Moody

Reports

As a leading producer of seafood in the United States, the Commonwealth of Virginia has long maintained an interest in the vitality of its private seafood industry. The present study focuses on the state's oyster industry which is distinguished for its long record of producing one-third of the entire national catch, but which, recently has suffered a variety of natural ·and economic setbacks. Herein, we.wish to examine the economic value of the subsidy programs enacted to meet these recent threats to the very existence of the Virginia oyster industry.

Oyster Spatfall On Shellstrings In Virginia Rivers: 1976 Annual Summary, Dexter S. Haven, Paul C. Kendall

Reports

The Virginia Institute of M3rine 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,

Assessment Of Surf Clam Stocks In Nearshore Waters Along The Delmarva Peninsula And In The Fishery South Of Cape Henry, Joseph G. Loesch

VIMS Articles

In 1974 the abundance of surf clams was sampled from Delmarva Peninsula, Delaware south to North Carolina. Surf clams were not found in commercial densities in the inshore waters along the Delmarva Peninsula. Off shore and south of Cape Henry, an area of intense surf clam fishing, the estimated standing crop was IO million bushels. A length-age relationship was estimated and it implies that recruitment to the fishery occurs at approximately age 2, at an average annual rate of about 8%. It is concluded that because of the low recruitment rate relative to the heavy fishing pressure that Virginia surf …

Importance Of Predation By Crabs And Fishes On Benthic Infauna In Chesapeake Bay, Rw Virstein

VIMS Articles

The significance of large motile predators in controlling the distribution and abundance of the macrobenthic invertebrates within the sediments (the infauna) in a shallow subtidal sand community was tested using manipulative field experiments. The blue crab (Callinectes sapidus) and 2 species of bottom—feeding fishes, spot (Leiostomus xanthurus) and hogchoker (Trinectes maculatus), were either excluded from or confined to small areas using wire mesh cages. Callinectes and Leiostomus effectively reduced infaunal desnities; Trinectes did not. The infauna responded to decreased predation with a large increase in density and diversity within 2 mo. The large population increases were exhibited by opportunistic species, …

Exploiting Natural Oyster Populations Through Waste Heat Utilization, Bruce J. Neilson

VIMS Books and Book Chapters

Oysters are filter-feeding organisms which can accumulate substances to concentrations far above those found in the surrounding water. Large acreages of estuary bottoms have been classified .as restricted for shellfish culture due to the presence of pollutants in the water and therefore, the likelihood of high levels of pollutants in oysters grown in those environments. Depuration is a natural process whereby oysters and other shellfish cleanse themselves of accumulated contaminants when they are placed in a clean environment. Recent studies have shown that bacterial depuration of oysters is feasible for the waters of Chesapeake Bay. Depuration is not possible, though, …

Disease Workshop, Virginia Institute Of Marine Science, 17-19 August 1977 : Mortality Studies, J. D. Andrews

Reports

In early years, we followed planted beds and ·oysters in trays for mortalities and prevalences of haplosporidans in live and dead oysters (gapers). We became convinced that diseases in oysters on beds and in trays were very similar in level of activity. Soon planted beds were lacking in lower Chesapeake Bay except in areas marginal for the disease......

Virginia Lobster Fishery, R. E. Harris Jr., W. A. Van Engel

Reports

Approximately 100% of lobsters landed in VIrginia are caught 60 to 80 miles off the coast. Prior to 1971 lobsters landed in Virginia were caught offshore by otter trawlers either incidental to finfish catch or by trawlers specifically in search for lobsters. , Several companies and several independent lobstermen have been fishing lobster traps since then. Few lobsters are now landed in Virginia by trawlers.

Aquaculture Thesaurus: Descriptors Used In The National Aquaculture Information System, James A. Lanier, Frances L. Lawrence, Elaine V. Collins, Mary B. Hollinger

Reports

The Aquaculture Thesaurus consists of the descriptors used in entering material into the National Aquaculture Information System {NAIS). Terms have been arranged in a format similar to that used in the Thesaurus of Water Resources Terms published by the U. S. Department of the Interior.

The National Aquaculture Information System is a NOAA project which provides computer assisted access to a broad range of information on growing marine, brackish and freshwater organisms. It was developed to answer the need for a centralized source of information in the U.S., and anyone with a need for information on aquaculture can use it.
