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).

A coral ring mount device and method for the propagative culture of sessile benthic marine organisms (for example, stony corals) employing either a ring, washer or threaded nut or similar as a propagule mount upon which the coral is set in order to attach, grow and overgrow within a coral nursery system. In the preferred embodiment of the invention, once the coral is grown onto the ring mount and to its requisite size and condition, the ring mount becomes the washer through which passes a screw to secure the ring and coral to the seafloor.

The invention provides a process for the production of seafood in a closed-loop multitrophic aquaculture system comprising the steps of: (A) culturing phytoplankton in a medium, wherein said medium is irradiated with light; (B) transferring such cultured phytoplankton to a medium for culturing zooplankton; (C) transferring such cultured zooplankton to a medium for culturing seafood; and (D) transferring a part of the medium of step (C) as nutritient to the medium of step (A), thereby creating a closed loop, wherein steps (A) to (D) are carried out in a closed system, in which free gas exchange with the environment is prevented. The invention further provides an apparatus for carrying out this process.

This invention relates to a confinement device for growing larvae or aquatic organisms in general, which allows the diversification of aquaculture. The device is modular and stackable. This invention relates particularly to a confinement device that makes it possible to keep larvae from multiple marine/aquatic organisms in confinement in their natural environment for them to undergo metamorphosis, maturation and settling of larvae that will subsequently become juveniles or seed for an industrial pre-fattening stage. The device also allows confining aquatic organisms in general, facilitating their development in culture. This invention also relates to a cultivation system and method comprising the use of said confinement device.

A deep water drawing step of drawing deep water that exists in a deep region of the sea to a surface region of the sea with an upwelling pipe (1); and a phytoplankton culturing step of culturing the phytoplankton in the upwelling pipe (1) are included to produce, as a basic producer of a food chain, a living marine resource, such as fishes and shellfishes, with phytoplankton produced in the phytoplankton culturing step.
