Oyster Reef In The Classroom – A Hands-On Laboratory Approach, Chesapeake Bay National Estuarine Research Reserve In Virginia

Reports

Grade Level: 7

Subject Area: Life Science

Students will examine different species found on an oyster reef in the Chesapeake Bay. Students will use a microscope and a dichotomous key to help them determine the different organisms being viewed. Students will draw conclusions based on the observed adaptations of the organisms about how the organism utilizes the oyster reef. Students will practice scientific sketching and become familiar with how to use a field guide and dichotomous key.

Analyses Of Kings Creek Water And Watershed Runoff Samples For Bacteroidales Using Qpcr To Detect Human Fecal Contamination, Howard Kator, Kimberly S. Reece

Reports

The purpose of this work was to evaluate and analyze water samples collected from the Kings Creek watershed using a qPCR-based method to detect both total Bacteroidales and Bacteroidales reported to be associated with human fecal contamination. Quantitative real-time PCR assays were used to significantly reduce processing times and at the same time yield estimates of target concentrations. Initial efforts focused on evaluation of various Bacteroidales primer sets reported in the literature tested against human and animal fecal samples collected from the Kings Creek watershed. Most samples, both animal and human, were positive with the universal (i.e. general or total) …

Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay, January 2011-December 2011 : Annual Progress Report, Leonard S. Machut, Mary C. Fabrizio

Reports

The 2011 striped bass juvenile abundance index is 27.09 and is significantly higher than the historic average of 7.92. Unlike previous years, the 2011 York River index was the highest among Virginia watersheds with high recruitment in both the Pamunkey and Mattaponi rivers. All individual river JAI values were significantly higher than their respective historic averages except for the Chickahominy River which was not significantly different from its historic average. This suggests a strong year class was produced in the Virginia portion of Chesapeake Bay in 2011. Sampling of auxiliary stations provides greater spatial coverage of the nursery grounds and …

Reduction Of Crab Mortality In Seed Cages, Richard W. Harding Jr.

Reports

The purpose of this project is to find out what cage design works best to let the crabs escape and reduce m01tality. My hope is this study will help others in the aquaculture industry reduce mortality and get more yield from their seed.

Testing Raised Footlines In Virginia's Striped Bass Fishery: A Gear Based Method Of Reducing Sturgeon Interactions In Anchored Gill Nets, George Earl Trice Iv

Reports

This project was conducted over a period of 39 days using two different net configurations and fishery locations in order to test methodologies to reduce the bycatch of Atlantic sturgeon while not affecting the striped bass fishery. Nets were hung using conventional methods allowing the net to rest on the bottom of the waters. Experimental nets were hung with a 3' bottom panel with no mesh allowing bottom dwelling fishes to swim under the "floated" net mesh. Nets were hung using mesh sizes ranging from 5.5" to 8". All catch was recorded and compared to determine the effects of the …

Stake In The Bay, Michael J. Gadwell

Reports

The Stake in the bay project was instituted to make it possible for people of all ages and agility to become involved in the oyster replenishment and restoration. This was accomplished by my wife and I utilizing over a dozen different recipes and types of stakes and slurri.es to encourage spat attachment using triploid larvae set in our onshore setting tank which is also utilized for setting spat on shell.

Feasibility Of A Recirculating Aquaculture System For Early Larval Culture Of Crassostrea Virginica, Michael Congrove

Reports

Oyster aquaculture in Virginia is a rapidly developing industry with greater than 75 million oysters planted in 2010, this compared to just 6 million in 2005 (Murray and Hudson 2011). Necessary to support this rapid development, among other things, is a large and consistent supply of larval and seed oysters, from which oyster growers start their crops. Providing this product to the aquaculture industry are hatcheries.

Hatcheries represent the tip of the pyramid in oyster aquaculture. Only a few hatcheries with a handful of workers support a much larger industry of many growout operations collectively employing hundreds of workers. Hatcheries …

The Status Of Virginia's Public Oyster Resource 2011, Melissa Southworth, Roger L. Mann

Reports

This report summarizes data collected during 2011 in the Virginia portion of the Chesapeake Bay. The report is composed of two parts, part one, oyster recruitment (shell string) in Virginia and part two, dredge survey of selected oyster bars in Virginia.
