Squidgly is a versatile tool for marine biology facilities, coral aquascaping and reef hobbyists. Designed to reduce hand and water contact while being an extension of your hand. Tool is a shaft available in different lengths. One side of the shaft includes a handle with a spring pulling mechanism. The other side of the shaft includes a unique detachable pair of claws/grabber. Handle and claws are internally connected in the shaft with a quick release design. Claws have an open resting position that will close and grab when the user pulls the handle mechanism. Each claw's shape and length is unique for the sole purpose of the design, but they are detachable, rotate 360, snap and lock into 45, 90, and 180. Using this tool will limit hand and water contact therefore reducing contaminants in the water, resulting in healthier corals, fish and clean water.

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.

A buoy that includes a first sensor to measure a change of an environmental event, a compartment that contains at least one organism, a second sensor to determine a maturity of the at least one organism, a release mechanism to release the at least one organism from the compartment to the body of water, an adjustable aperture nozzle mounted to the buoy to disperse the at least one organism from the compartment in a rate proportionate to the change of the environmental event with a quantity of the water from the body of water, and a control operable to adjust the release mechanism.

A floating power generation unit is provided which, by dispersing oxygen content in water as fine air bubbles while generating power on the water, increases the activity of aerobic organisms, promotes plankton growth, and improves fishing grounds. This floating power generation unit is provided with a power generator, an oxygen separator, and a float. The power generator and the oxygen separator are arranged on the top surface of the float. The floating power generation unit is provided with a first fine air bubble generating medium which supplies the oxygen separated by the oxygen separator into the water as fine air bubbles and is provided with a second fine air bubble generating medium which supplies the nitrogen separated by the oxygen separator into the water as fine air bubbles.

The present disclosure relates to shaped cementitious compositions that comprise a substrate for aquatic flora and/or fauna attachment; methods for providing a substrate for aquatic flora and/or fauna attachment comprising depositing a shaped cementitious composition into a body of water; and methods for making a shaped cementitious composition. The shaped cementitious composition is formed from a pourable cementitious mixture comprising: (a) a pozzolan comprising a natural pozzolan and/or a manmade pozzolan; (b) MgO and/or Mg(OH).sub.2; (c) an aqueous solution comprising one or more accelerants; and (d) at least one aggregate. In some cases, the MgO and/or Mg(OH).sub.2 of (b) is included in the aqueous solution of (c). And, in various cases, the manmade pozzolan comprises a slag.

The feed production device includes a first water tank in which bacteria and plankton are raised, and a second water tank in which the bacteria and plankton that are raised in the first water tank are annihilated to create a feed for leptocephalus.
