The present disclosure provides systems for heat source, e.g., data center, cooling and aquaculture. In certain aspects, the systems include a heat source, e.g., data center, having a water cooling subsystem configured to receive cool water and output warm water and an aquaculture center co-located with the heat source, e.g., data center, and configured to receive the warm water. Aspects of the invention also include methods for cooling a heat source, e.g., data center, using a water cooling subsystem and cultivating aquatic organisms with an aquaculture center that is co-located with the heat source, e.g., data center.

An apparatus and method for promoting macrobenthic growth in a waterway. The apparatus comprises a biodegradable net bag with a biodegradable panel insert that is adapted to receive a biomass Suitable for attracting and promoting macrobenthic growth. The method comprises providing a suitable net bag, filling it with an appropriate biomass, deploying it in a healthy waterway until macrobenthic growth has become established, and transporting and redeploying it in a second waterway requiring remediation.

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.

The system, apparatus and method of the present invention provides for the cultivation of shellfish in subtidal environments. A key aspect of the invention is the use of specially configured baskets, into which the shellfish to be grown is seeded. In particular, the baskets are configured with a support bracket through which a cable passes. The mounting of the support bracket permits the rotation of the basket and allows a shellfish cultivator to replicate the growing conditions of intertidal ecosystems despite the invention being used in a subtidal environment.

There are provided a pearl culture material containing at least one selected from the group consisting of a pearl nucleus and a mantle, and the at least one selected from the group consisting of a pearl nucleus and a mantle contains a protein having 10 EU/g or less of an endotoxin amount, a nucleus insertion method, and a pearl culture material composition.
