When you farm shellfish on Massachusetts’ beautiful coastal marshes, the world is your oy-stah! At least according to Brenden Doyle, a Gloucester native with family roots in Massachusetts’ commercial and recreational fishing industry. He spent his childhood boating and fishing around Cape Ann and learning about the unique ecology that defines the North Shore.
His love of the sea led him to his first career with the U.S. Navy. While he later worked in IT, he always wanted to find a way to work on the water again. Inspired by family members who farm scallops and salmon in Nova Scotia, he purchased a 3.8-acre section of marshy wetland in 2018. After 3 1/2 years, he secured permits and started The Great Salt Marsh Company.
The company operates in the heart of the Great Marsh, the largest contiguous salt marsh in New England. It has more than 25,000 acres of pristine waters that offer rich tidal waters for oysters. The farm sits at the mouth of the Rowley River, which provides critical nutrients for oysters and muddy flats for oyster cages.
Farming Oysters from Tide to Table
The Great Marsh Shellfish Company’s oysters grow in an incredibly productive environment. Oysters, like wine grapes, develop their flavor profile from where they are grown. They offer a unique taste of the place. The salinity of the Rowley River estuary, abundant algae, and marsh grasses create the distinctive flavor profile. Brenden describes his oysters as brine-forward and sweet, with a bright grassy aftertaste.
The oyster seeds are sourced from hatcheries in Maine. At 2 millimeters long, oysters start in the farm’s specialized nursery and move through a series of grow-out equipment to condition their shells. Throughout the process, oysters are handled often to develop the deep cups ideal for shucking. This intricate process of moving each individual oyster through these stages is incredibly labor intensive. This year, Brenden’s team will hand sort more than 1 million oysters. All this hard work pays off in high-quality oysters for the market.
