The perfect food may not be underfoot, but rather, underwater. It’s delicious, fast-growing, nutritionally dense, sustainably produced, locally available from coast to coast and comes in nature’s own sturdy packaging. “Shellfish is the most sustainable protein on the planet. There are no antibiotics, no pesticides, no fertilizer and no feed needed to raise shellfish,” says Bob Rheault, executive director of the East Coast Shellfish Growers Association, which represents 1,500 shellfish farmers from Maine to Florida. Shellfish is a nutritional powerhouse, providing proteins, essential amino acids, long-chain polyunsaturated fats, vitamins and carotenoids. The drastically shorter life cycle of shellfish compared to other farmed seafood also means shellfish producers can generate more food more quickly. Shellfish also offer many ecological benefits; they filter the water, remove excess nutrients and create habitat for juvenile fish, Rheault says. A single oyster can filter up to 50 gallons of water per day, according to the Oyster Recovery Partnership, an organization that restores reefs in conjunction with a shell recycling network of restaurants and public drop sites across the mid-Atlantic region. Ray Hilborn, a biologist and professor at the University of Washington School of Aquatic and Fishery Sciences, in Seattle, has compared the relative environmental costs of different food sources, including grains, poultry and imitation, plant-based meats. He has found that farmed shellfish, specifically mollusks like oysters, clams and mussels, provide the lowest impact protein of them all. “Shellfish has a very low carbon footprint and enormous yield per area,” he says. “Mussel farms, for example, are pretty much just ropes hung from rafts, with no changes to the ecosystem or loss of biodiversity, as compared to agriculture.” Bivalve shellfish like clams and oysters are mainly sourced from farms because wild stocks are largely depleted due to overharvesting, habitat loss and other contributing factors. “Somewhere
