University of Maine researchers have successfully hatched and reared juvenile Atlantic halibut.


Now, as Maine’s wild fisheries are further depleted and restricted, the scientists and their business partner are ready to raise the darkish brown flatfish to market size and test whether land-based halibut farming is a viable seafood enterprise.

Last week, UMaine staff and Maine Halibut Farms President Alan Spear were busily grading and moving thousands of juvenile halibut from the UMaine Department of Industrial Cooperation’s Center for Cooperative Aquaculture Research’s nursery to recirculated-seawater tanks where the fish will be grown to 2 to 10 pounds.


Some halibut already were marketed last year to notable Maine restaurants such as Cleonice Mediterranean Bistro in Ellsworth and Fore Street restaurant in Portland.


Nick Brown, operations manager of the Center for Cooperative Aquaculture Research (CCAR), and staff were also closely monitoring and collecting eggs from Lana, Wanda, Daisy, Neissa, Sylvia, Violet and other spawning female halibuts housed in 21-foot-round brood tanks fabricated locally by Tom St. Claire of Sullivan Plastic Products. The breeding season runs from mid-February through May.

“We only expected to rear a few thousand fish, but these systems were so successful, we wound up with 25,000 fish last year. This bodes very well for the future because our building was designed to rear 100,000 juveniles at expected survival rates,” Brown related last Friday.


He ran a successful halibut farm in Digby, Nova Scotia, before being hired six years ago to manage the applied research facility on Taunton Bay.


“We have shown we can produce the fish and we are now building the grow-out systems,” he said.


In 1999, UMaine purchased an existing Franklin salmon farm and established the Center for Cooperative Aquaculture Research. CCAR’s mission is to explore new marine species and develop related technology to enhance and expand the Maine aquaculture industry. Sea urchins are among the other sea creatures being studied there.


“Seafood consumption is increasing in the U.S. Yet, 70 percent is imported. The trade deficit on seafood is $8.2 billion,” Brown noted. “Half of the seafood we consume is aquaculture-produced or could be. Clearly, we want to increase domestic production of aquaculture products.”


Once a grow-out system has been developed in Franklin, Maine Halibut Farms aims to start a land-based commercial venture in the Gouldsboro village of Corea as part of the new Gulf of Maine Aquaculture Business Park envisioned at the former U.S. Navy communications center. The Holden-based company would be one of as many as 10 corporate tenants engaged in fishing-farming and other aquaculture activities on site.


Acadia Capital Corp., an affiliate of Eastern Maine Development Corp. (EMDC), owns 40 acres on the 450-acre property vacated by the U.S Department of Defense in 2002. ACC secured a $335,700 Community Development Block Grant last year, but is still awaiting word on a $450,000 grant, which would furnish matching funds, from the U.S. Department of Agriculture.


John Holden, director of business development at EMDC, is hopeful he’ll get answer this spring.


“Until they get their federal allocation,” Holden said Monday, referring to the U.S. Department of Agriculture, “they can’t make any decisions.”
