An apparatus and method for coral husbandry including a frame configured to attach to an aquaculture raceway, a carriage having a plurality of tools mounted thereon, the carriage being attached to the frame and configured to move relative to the frame, the plurality of tools comprising a rotary tool having a tool member attached thereto, a nozzle configured for at least one-way fluid communication, and an inspection instrument for monitoring and cataloguing coral reef specimens.

The present invention provides a new energy-driven in-situ plankton collecting device, comprising a solar photovoltaic cell and wind power generation system, a buoyancy support system, a power supply and control system, a plankton suction and collection system, and an anchoring system. The device has the center of gravity on the lower part and vertically floats in water like a tumbler. The plankton suction and collection system is composed of a suction axial-flow pump and a collecting cod end. The bag-shaped plankton collecting cod end has the mesh aperture of less than 0.8 time the average body length of the target plankton, and can be used on both sides. The devices provided by the present invention can be used simultaneously and arranged in an array for collection and utilization of plankton as well as governance and remediation of water area environment, and thus have a favorable application prospect.

The present invention is a new process for preserving the water of an aquatic body as a supplying source for different human activities such as recreation and amusement, food and ornamentation, by the development of a aquatic space formed by a Open water Lake, a Spa Lake, and a Water Depuration Lake that preserves the water mass by biotransformation and mineralization that allow reducing the concentration of carbon, nitrogen and phosphorous, generating clean and transparent water without the use of large amounts of chemicals and complex filtrate systems.

Examples of the disclosure provide for an apparatus for actively restoring and promoting marine life. Said apparatus includes a mounting component and a receiver component. Said mounting and receiving components are capable of mechanically joining with each other. Said mounting component provides a base for stable attachment of a living sessile organism. Said receiver component provides stable anchoring for said mounting component. Various embodiments of said apparatus function to facilitate propagation, protective transport and efficient out planting of said organisms in a submerged marine environment.

There is provided herein a method of treating a poikilothermic organism, such as marine bivalves, in a decreasing temperature environment which method comprises exposing the organism to a source of eicosapentaenoic acid (EPA) at temperatures of from 18 C. to about 12 C., and then exposing the organism to a source of docosahexaenoic acid (DHA) at temperatures of from about 11 C. to about 5 C. There is also provided herein a method of just conducting the first or second exposing step without the other, and also a method of using a decrease in temperature to catalyze the organism to produce EPA and/or DHA and/or non-methylene-interrupted fatty acids (NMIs).
