August 6, 2025 — Much of the scallop farming techniques used in the U.S. derive from practices in Japan, where scallops have long been a part of the country’s seafood industry. Researchers from the University of Maine are working to test and adapt those practices to help grow the industry in the Gulf of Maine, where oyster farming is currently the most well-known form of aquaculture in Maine’s blue economy.
Building off a four-year study published in the spring, which compared the effectiveness of two different Atlantic sea scallop farming techniques, UMaine researchers further analyzed the economic advantages and disadvantages of the same two methods of scallop aquaculture. Lead researcher Damian Brady, professor of marine sciences at UMaine, and co-author Chris Noren, a postdoctoral researcher, used their results to develop a user-friendly application that helps interested parties compare the different costs and possibilities associated with building their own scallop farms.
“Now new farmers can make educated decisions on what option is going to be most viable for them, taking into account their location, timeframe, budget and all the other pieces that go into scallop farming,” Brady said. “Ultimately, our goal is to help Maine grow this industry to its fullest potential and preserve Maine’s working waterfronts—an integral part of the state’s culture and history.”
Published in the journal Aquaculture, the study looked at two of the most common options for scallop farming: lantern net and ear-hanging. Previously, lantern net methods were thought to be more cost-effective, but this study shows the ways in which the ear-hanging method can be more cost-efficient over a longer period of time.
