What We Do
Virginia Sea Grant aims to maintain sustainable and thriving commercial and recreational fisheries and aquaculture production in Virginia through cutting edge research and "feet on the boat" extension work. Extension staff at VIMS and Virginia Tech specialize in fishing gear design, recreational fisheries, and finfish and shellfish aquaculture.
Extension projects include:
- Sustainable Commercial Fisheries
- Virginia Game Fish Tagging Program
- Fisheries Resource Grant Program
- Aquaculture Program at VIMS Marine Advisory Services
- Virginia Aquaculture Conference
- Aquaculture Program at Virginia Tech's Virginia Seafood Agricultural Research and Extension Center (VSAREC)
Current research and extension work is featured below
Over the next three years Mark will use quantitative modeling to investigate the effects of external influences—including human, food web, and environmental factors—on dozens
Over the next three years, Ben will investigate the effects that seasonal oxygen deficiencies and rising water temperatures have on spot and Atlantic croaker.
There’s still a lot to learn about all the factors that influence the abundance and distribution of fish stocks. Mark Stratton of Virginia Institute of Marine Science will use quantitative modeling to investigate the effects of human, food web, and environmental factors on dozens of near shore fish populations in the US South Atlantic. He […]
Some researchers suspect that seasonal oxygen deficiencies and rising water temperatures are causing fish in the Chesapeake Bay to move to suboptimal habitats. These habitats may be contributing to increased mortality rates and decreased population growth in fish species. Ben Marcek of Virginia Institute of Marine Science will use data on water temperature, oxygen […]
Defining the effects of habitat availability on population dynamics may be a critical part of creating sustainable fishing policies. Megan Wood of Virginia Institute of Marine Science will develop a model to better understand blue crab distribution patterns and will study the effects of Gracilaria vemiculophylla, an exotic red alga, in blue crab nursery habitats. […]
When saturated with excess nutrients, a body of water of water may suffer from reduced levels of oxygen and an unbalanced ecosystem. Could the solution to this problem be just below the water’s surface? Abby Lunstrum of University of Virginia will investigate whether oyster farming has the potential to reduce the harmful effects of nutrient […]
NOAA Chesapeake Bay Office and Virginia Sea Grant announce a two-year, postgraduate fellowship. Apply by July 19, 2014.
Virginia Sea Grant affiliated extension at Virginia Institute of Marine Science is collaborating with Smithsonian Environmental Research Center Scientist to learn more about cownose ray migration.
Virginia Sea Grant extension at Virginia Tech manned a booth at the Hampton Crabtown Environmental Expo on June 7, 2014. The Expo featured booths and talks about oysters, crabs, aquaculture, sustainability, wetlands, and more. Abigail Villalba, Virginia Sea Grant extension at Virginia Tech’s Seafood Agriculture Research and Extension Center in Hampton, was there to talk […]
“You can’t just approach a fisherman and say, ‘this is what I want to do with your gear’,” says Virginia Sea Grant Fellow Tony Nalovic. “You need to come up with ideas together.”

According to annual report, Virginia’s shellfish aquaculture industry continues growing, reaching all-time sales and production highs in 2013.
Virginia Sea Grant research into the minds of consumers reveals to opinions about quality of aquaculture and wild-caught seafood.
A hot topic at the 2013 Virginia Aquaculture Conference this past November was how to maintain the safe consumption of raw oysters and better understand the science that directs industry harvest regulations.
In the end, there are many definitions for aquaculture or agriculture, and none of them are universal.
Virginia’s bi-annual conference for fish farmers, held in Newport News on November 15 and 16 of last year, drew more than 100 finfish and shellfish growers.
When Annie Murphy came to Virginia to study nutrients in Chesapeake Bay, she didn’t expect her studies would lead her to Italy.
Members of the seafood processing industry learned how to make more with less at Virginia Sea Grant’s 2013 Value-Added Seafood Marketing Workshop.
The cownose ray has been in the industry crosshairs ever since they’ve been seen gobbling up shellfish crops. As industry considers the range of options for keeping rays off shellfish farms, including developing a commercial fishery, new research about cownose ray biology may help in making those decisions.
