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.

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.

A flow passage (70) is shown in the form of two successively linked, substantially parallel, adjacent, open top channels (12A, 14A) to form part of an algae cultivation system. The forward flow of the water passes in sequence through the respective open top channels (12A) and (14A) of flow passage (70), in the direction of arrow A and then is then recirculated back into to the channel (12A), and so on. The combination of added nutrients, sunlight and agitation of the fluid flow encourages the growth cultivation of the biological organisms which are continually suspended in the flowing water. Such a flow passage (70) can be used as a standalone passage used as part of a system for cultivation of biological organisms, or it can also form one basic unit of a modular system which is arranged in use to have several such flow passages linked together in use. Such a reconfigurable apparatus gives the user the flexibility to cultivate different algae products both separately and simultaneously.

Disclosed herein is a feed composition that promotes the growth of zooplankton, enhances the survival rate of zooplankton, is safe, and has little adverse effect on the environment. The feed composition for zooplankton contains PHA.

A photobioreactor device for growing photosynthetic organisms, organisms that feed on photosynthetic organisms and hydroponics is disclosed. The device may include a lighting system integrated around the circumference of the device. In embodiments, a cap configured to seal the container has ports configured to permit passage of fluid out of or into a container without removing the cap. In some embodiments, organisms are grown in a disposable bag secured between the cap and the container.
