Could offshore clamming become a thing?
By Kitta MacPherson
Rutgers researchers have made a discovery that could change the future of seafood farming in New Jersey.A study led by marine scientist Daphne Munroe has
shown that Atlantic surfclams can be successfully farmed in the open ocean.
Her research, published in the North American Journal of Aquaculture, proves that offshore aquaculture is not only possible but promising. This method could help meet the increasing demand for seafood while protecting wild clam populations.
“We’re among the first to show that offshore clam farming
can really work,” said Munroe, an associate professor in the Department of Marine and Coastal Sciences in
the Rutgers School of Environmental and Biological Sciences. “It’s exciting
because it opens the door to a new kind of business for New Jersey’s farming
and fishing industries.”
The study was funded by a grant from the National Oceanic
and Atmospheric Administration and was done in partnership with commercial
fishing companies.
“We didn’t do this in a lab,” Munroe said, emphasizing the
importance of working with industry partners. “We did it in the real world,
with real fishermen. That’s what makes the results so meaningful.”
Aquaculture is the practice of farming fish, shellfish and
other aquatic organisms. It’s similar to agriculture, but instead of growing
crops on land, farmers raise seafood in water. Most aquaculture takes place
near the shore in protected bays or in artificial ponds and lakes.
These areas are easier to manage and safer from storms, but
they are crowded with other user groups like homeowners and boaters and can be
subject to poor water quality which can hinder farm operations. Offshore
aquaculture avoids these challenges, Munroe said, by using the vast, cleaner
waters of the open ocean, where there is more room and less potential for
pollution.
Members of Munroe’s team wanted to test whether surfclams,
which are large, hard-shelled shellfish that live buried in sandy ocean
bottoms, could be raised offshore, where space is more available. The clams,
commonly used in chowders and fried clam strips, are an important part of New
Jersey’s commercial fishing industry.
