Scallops
From the Melissa Clark in the NYTimes - "There are only a handful of sea scallop farms in the United States, and most are in Maine, run by fishing families. Mr. Brewer and his son, Bob, pulled up a long algae-covered net and scooped scallops into a bucket of seawater, where they zipped around, moving a whole lot faster than you’d think bivalves could. Most would go to Glidden Point Oyster Farms. The rest were about to become lunch."
"Bivalve farming (along with kelp farming) is one of the most environmentally beneficial types of aquaculture, considered a zero-input food source because it doesn’t require any arable land, fresh water or fertilizers to grow protein. You don’t even need to feed bivalves; phytoplankton already present in the sea will sustain them." - https://www.nytimes.com/2021/08/23/dining/maine-sea-scallops.html
Yes, in addition to Oysters, we have Scallops up here. And Glidden Point is a mile down the road from us...
