Stakeholders Of The Chesapeake: Curse Of The Eastern Oyster. Subjects: Life Science / Biology, Environmental Science, Marine/Ocean Science Grades: 6-8, Taylor Goelz Jan 2017

Stakeholders Of The Chesapeake: Curse Of The Eastern Oyster. Subjects: Life Science / Biology, Environmental Science, Marine/Ocean Science Grades: 6-8, Taylor Goelz

Reports

How do we decide how to manage oysters and who has a stake in that management decision? Students are placed in the role of a stakeholder group who cares about what happens to the Eastern oyster and asked to rank management priorities from the perspective of their group and others. Through viewing oyster management through a single perspective, students can begin to understand that balancing stakeholder’s views in setting policy and management is challenging.


Practical Oyster Larvae And Remote Deployment Pool, Albert Pollard Jan 2016

Practical Oyster Larvae And Remote Deployment Pool, Albert Pollard

Reports

This grant will evaluate the costs of constructing and operating a 100 bushel “floating pool” in which aged, washed, and containerized shell is placed with purchased larvae for setting on the cultch. The 100 bushel sized pool is being proposed because it is a sample size large enough to test future scalability but small enough to manage as a controlled experiment. In addition, the proposal will compare the setting efficiency of the pool vs the standard upland tanks. Also, we intend to test practicality - after lifting the skirt that forms the pool – of towing the POLARDS Pool (now a barge ...

Reports

1. The overarching goal of the Chesapeake Bay Foundation (CBF) for this project has been to enhance the Chesapeake Bay’s oyster population. In Virginia, CBF is working with partners to focus restoration efforts on the Lafayette River in order to bring the river’s biomass and reef substrate to a threshold level that will show a systemic response in terms of enhanced spatset. Portions of their grant have funded the hydrodynamic modeling of the Lafayette River recently performed and herein reported. 2. VIMS personnel have modified its existing three-dimensional hydrodynamic model of the Lafayette/Elizabeth/James Rivers to conduct ...

Population Assessment Of Eastern Oysters (Crassostrea Virginica) In The Seaside Coastal Bays, Paige G. Ross, Mark Luckenbach Feb 2009

Population Assessment Of Eastern Oysters (Crassostrea Virginica) In The Seaside Coastal Bays, Paige G. Ross, Mark Luckenbach

Reports

Declines of oyster populations and commercial harvest from the Virginia seaside coastal bays have followed similar patterns, though not as severe, as those in Chesapeake Bay. High prevalence of Dermo disease (Perkinsus marinus) and MSX disease (Haplosporidium nelsoni) coupled with over harvest and habitat destruction have dramatically reduced populations. Nevertheless, there are several promising signs that significant enhancement of the population could be achieved with well conceived restoration efforts. Oyster habitat and population distribution were examined in the coastal bay system on the seaside of the Eastern Shore of Virginia. This system is composed of barrier islands, salt marshes, broad ...

The maps are generated to illustrate the results of the targeting effort following the protocol described above. The authors recognize this level of targeting does not preclude the need for field inspection at potential sites prior to reef construction. The atlas is comprised of a series of boxes preceded by an index locator. The scale of each box may vary. The potential restoration areas are illustrated in red. The legend reports the total acres available for restoration within the boundary of each box. At this time, the size of individual restoration sites can only be retrieved using the digital data ...

A Comparative Field Study Of Crassostrea Ariakensis And Crassostrea Virginica In Relation To Salinity In Virginia, Gustavo W. Calvo, Mark Luckenbach, Standish K. Allen Jr., Eugene M. Burreson Mar 2000

A Comparative Field Study Of Crassostrea Ariakensis And Crassostrea Virginica In Relation To Salinity In Virginia, Gustavo W. Calvo, Mark Luckenbach, Standish K. Allen Jr., Eugene M. Burreson

Reports

In accordance with the Rational Plan for Testing Application of Non-Native Oyster Species (VIMS 1996) we conducted a field experiment to examine survival, growth and disease susceptibility of Crassostrea ariakensis (=rivularis) in relation to salinity in Virginia. The performance of triploid C. ariakensis in comparison with that of diploid C. virginica, (n = 250, age = 2 years, mean shell height = 60- 64 mm) was evaluated at replicate sites within low, medium, and high salinity regimes (respectively, < 15‰, 15-25‰, > 25‰) in Chesapeake Bay and the Atlantic Coast. During the course of this study, from June 1998 to September 1999, there was a severe oyster ...

Filtration By Oysters : Interactive Effects Of Water Flow, Seston Composition And Filtration Rate, Mark W. Luckenbach, Deborah A. Harsh, Roger L. Mann, R J. Orth, Ken Moore Jan 1995

Filtration By Oysters : Interactive Effects Of Water Flow, Seston Composition And Filtration Rate, Mark W. Luckenbach, Deborah A. Harsh, Roger L. Mann, R J. Orth, Ken Moore

Reports

Filtration by suspension-feeding bivalves affects water quality and the postulated impacts include increased light penetration and enhanced benthic primary production. Such system-level predictions are extrapolated fiom still water experiments which neglect the effects of flow, seston composition, turbulent mixing and refiltration by oysters within groups. Flume experiments were used to investigate the effects of varying flow speed and seston composition on filtration capacity of oysters. Six groups of 90 oysters were used in treatments which varied concentrations of the algae Ekalassiosira weisj70grgrsie parately and in combination with inorganics; four sets of shell only controls were used to evaluate hydrodynamic effects ...


A Comparative Study Of Dry Weight Measurements Of Oyster Soft Tissue, Cheol Mo, Bruce Neilson Jun 1992

A Comparative Study Of Dry Weight Measurements Of Oyster Soft Tissue, Cheol Mo, Bruce Neilson

Reports

Four alternative drying methods for oyster soft tissue were compared: oven drying at 105, 100 and 80°C and freeze drying. Weights were recorded every 12 hours for 5 days, and after sample treatments were switched, every 24 hours for another 3 days. The time required for all of the oysters in a treatment to reach constant weight were 36, 36, 60, and 120 hours for the 105, 100, 80°C ovens and freeze drier respectively. Within a treatment, the time for an individual oyster to reach constant weight was not related to that weight. For oven drying, drying was ...

The James River Public Seed Oyster Area In Virginia (A Review Of 22 Years Of Setting And Population Studies, 1946 To 1967 And Changes Caused By Minchinia Nelsoni (Msx) After 1960), Jay D. Andrews

Reports

The seed-oyster area is located in a low-salinity sector of the James River where seasonal riverflows and resulting salinities vary widely. Low spring salinities, usually below 10 °/oo in April or May, eliminate most predators and diseases. Prior to 1960, spatfalls were regular and moderate in intensity each year. High quality seed oysters 2 to 3 inches in size were produced with 1000 to 2000 thick-shelled oysters per bushel for use by private-ground planterH. Following the advent of M. nelsoni (MSX) in Chesapeake Bay in 1959:, setting declined to about one-tenth previous levels and there were spatfall failures in many ...
