On one of the calm, unseasonably warm early December days we had last month, my husband Isaac took our three-year-old son Emmett and me scalloping in Menemsha Pond for the first time. With each dump of the drag on the culling board we were amazed by what we found — tiny sea robins and flounder that Emmett put in a bucket on the deck, jellyfish, eel grass, and an incredible bounty of bay scallops with their beautiful fan-shaped shells.
