Abstract: Provided are systems and methods for farming bivalves, such as clams, oysters and scallops, using the principles of geothermal cooling. The system comprises a housing for containing the bivalves and a fluid distribution system configured to move water from a relatively warm body of water, such as an inlet to an ocean, to the housing. The fluid distribution system includes a conduit having an outer surface in thermal contact with a natural thermal reservoir with a temperature cooler than the body of water. The conduit is configured to transfer energy from the water to the thermal reservoir to cool the water and to pump nutrient-rich cooler water through the housing containing the bivalves.
