Dr. Ed Hale, assistant professor at the University of Delaware and the Delaware Sea Grant, as well as a member of the Delaware Environmental Coalition (DECO), told Sussex County Council members this week that the First State’s aquaculture industry is nowhere near capacity yet. Support will be needed to see it continue to grow in ways that could also benefit the local tourism industry, he added.

Ed Hale, an assistant professor in the University of Delaware’s School of Marine Science and Policy, and fisheries and aquaculture extension faculty with Delaware Sea Grant, sits on the council. One of his recent projects was overseeing the creation of the state’s first oyster hatchery at the university’s Lewes campus a couple years ago.

Assistant Professor Edward Hale, who is leading the project, believes that growing oysters in a facility and distributing those seeds to local farmers will provide a significant boost to Delaware’s economy. "The more oyster farmers we have, the more oysters we can grow, and the better we're going to do for our local environment," Hale said. "Making that connection is really important."

After the city of Wilmington removed a Brandywine dam in 2019, University of Delaware scientists discovered American shad returning to the area to reproduce. One fish the researchers tracked even made its way to Nova Scotia, Canada, and back, said assistant professor Ed Hale, who helped lead the research.

“There’s a group of us that have essentially been trying to really develop what would be a shellfish hatchery in the State of Delaware," Hale said. "So this is an effort that I’ve been working on with a colleague of mine - Dennis McIntosh at Delaware State University - as well as a couple other folks. We’re just trying to determine the feasibility of how to do this and how to execute it properly.”

Oyster-based restoration projects, particularly living shorelines, are being installed to protect coastal ecosystems and infrastructure. While these installations often successfully create aquatic habitats, further refinement in optimizing the growth potential of shellfish on shoreline installations will increase the success rate and efficiency of restoration projects.

The global shellfish aquaculture industry has expanded over the last seven decades. Similarly, the size of individual shellfish farming operations has grown in some states. Circulation processes in natural water bodies are dynamic and vary across multiple temporal and spatial scales. How gear installation affects the circulation of currents and waves, and subsequent phytoplankton delivery to crops within farms, is largely unknown.

Estuaries include some of the most productive yet anthropogenically impacted marine ecosystems on the planet, and provide critical habitat to many ecologically and economically important marine species. In order to elucidate ecological function in estuaries, we must understand what factors drive community dynamics.
