October 23, 2019 — Aquaculture is currently the third-most lucrative fishery in New England, after lobster and scallops. Oysters, and increasingly, kelp, are two of the most commonly grown foods.
Now, a new study says aquaculture could also be an important way to address issues like nutrient pollution and habitat loss. The study found that New England’s waters are among the top 20 locations in the world with the greatest opportunities for restorative aquaculture.
Aquaculture hasn’t been associated with environmental benefits, historically — in fact, it’s much more commonly known for pollution, when too many fish are crowded into coastal waters.
But it turns out that shellfish and seaweed, farmed properly, can dramatically improve water quality.
“Shellfish and seaweeds are at the bottom of the food web and they’re able to actually take up nutrients from the water column,” said Seth Theuerkauf, aquaculture scientist with The Nature Conservancy and lead author of that global assessment.
