THE OYSTERS WE EAT ARE TYPICALLY PRODUCED BY OYSTER FARMERS WHO PURCHASE SEED FROM HATCHERIES FOR GROW-OUT TO MARKET SIZE ON STATE-LICENSED OFFSHORE LEASES. THE SYSTEM IS BURDENED BY ECOLOGICAL AND REGULATORY CONSTRAINTS AND INCREASINGLY THREATENED BY ADVERSE WEATHER, PREDATION, AND DISEASE, AND IS HIGHLY INEFFICIENT. AN EXCELLENT SOURCE OFPREMIUM-QUALITY PROTEIN, OYSTERS WERE ONCE ABUNDANT AND CHEAP, BUT HAVE LARGELY DISAPPEARED FROM THE AVERAGE PERSON'S DIET.MAINE SHELLFISH DEVELOPERS LLC IS TRANSFORMING SHELLFISH FARMING TO 100% ONLAND CLOSED-CONTAINMENT PRODUCTION - KEEPING THEM WHERE THEY BEGAN LIFE ALL THE WAY TO MARKET-SIZE. YEAR-ROUND, ENVIRONMENTALLY INSULATED, AND OFFERING LARGE-SCALE EFFICIENCIES, THIS CAN MAKE A MAJOR CONTRIBUTION TO SUSTAINABLE NATIONAL AND GLOBAL FOOD SECURITY.
