New guidelines aim for sustainable growth of MA aquaculture

New global guidelines for aquaculture aim to address growing concerns about the industry's impact on the oceans.

Scientists have suggested ways to protect aquatic ecosystems, reduce antibiotic use, and even prevent ocean litter from discarded aquaculture gear.

Danielle Blacklock, director of the Office of Aquaculture at the National Oceanic and Atmospheric Administration, calls the guidelines "a big deal," as consumer demand for seafood outpaces supply.

"We're developing a new food system for the first time in millenia," said Blacklock. "That means that things are changing quickly. We're learning fast. We're adapting."

Blacklock said the U.S. currently imports up to 85% of its seafood.

She said the new guidelines should help level the playing field for Massachusetts farmers to ensure they, too, can reap the financial benefits of aquaculture while using sustainable practices.

For the first time, the amount of seafood produced on farms has surpassed the amount harvested from the wild, according to the United Nations.

Critics of finned fish farms, in particular, say they're no different than land-based factory farms and are detrimental to ocean habitats.

But Blacklock said aquaculture, including New England's numerous shellfish and kelp farms, will play an important role in countering food insecurity.

"When we mix climate change with our growing population," said Blacklock, "it clearly starts to rise to the top as part of our solution set to fight hunger."

Blacklock said the new guidelines also suggest ways aquaculture itself can reduce its carbon footprint.

She said the new guidelines are voluntary - but if implemented, they could help lift local economies and coastal communities, while building climate change resilience.
