A Rutgers University study has demonstrated that Atlantic surfclams can be successfully farmed far from shore, opening new opportunities for sustainable seafood production.

Led by marine scientist Dr Daphne Munroe, researchers placed over 300,000 juvenile clams in specially designed cages miles off the New Jersey coast. The cages protected the clams from predators, allowed cleaner water flow, and withstood rough ocean conditions. Clams deployed in spring grew faster and survived better, and the resulting meat quality was excellent.

Offshore aquaculture could reduce pressure on wild populations, avoid crowded coastal waters, and support local fishing industries. “We did it in the real world, with real fishermen,” said Dr Munroe. “This shows offshore aquaculture can be productive, environmentally responsible, and a win-win for people and the ocean.”
