There is provided processes and uses of an inline saturator for maintaining fish in a cage in an open body of water, the process comprising: restricting movement of water into and out of a part of the cage and forming a portion of water within the part of the cage. The process also includes injecting oxygenated water produced by an inline saturator into the portion of water to raise a dissolved oxygen level and to lower a dissolved nitrogen gas level therein. A treatment process is also provided that includes the steps noted above and further including introducing a medicinal substance into the oxygenated water or the portion of the body of water.

Embodiments of the present disclosure describe an aquaculture environment control system comprising one or more control apparatuses positioned within a vessel at an angle relative to a proximal vessel wall and configured for scouring of the vessel, wherein each control apparatus has a discharge conduit and each discharge conduit has one or more orifices; and a fluid source in fluid communication with each of the control apparatuses. Embodiments of the present disclosure describe a method of controlling an aquaculture environment comprising supplying one or more of a fluid and gas to a control apparatus positioned within a vessel at an angle relative to a proximal vessel wall; and discharging one or more of the fluid and gas from the control apparatus at a fluid velocity sufficient for scouring of the vessel.

Method for cultivating paralarvae of the common octopus, Octopusvulgaris up to the settlement thereof (benthic phase), based on a diet of prey containing the caprellids Pfttisica marina and CaprelIa equilibra and/or gammarids of the genus Jassa spp. Factors such as light conditions, water renewal and temperature, inter alia, are optimized to obtain maximum paralarvae survival.

A delivery device and system to supplement CO.sub.2 in an underwater environment without the need for electricity or the use of compressed CO.sub.2. The device consists of a container containing a biological organism such as mycelium and including an exit portal for CO.sub.2 to enter the underwater environment. The device may also incorporate a separation device to delay and control the flow of CO.sub.2. The system requires the device to be held in place through a securing point in the underwater environment. The minimum requirements for the device are described, but in certain instances it will be preferably used with a double-bag or an outer shell housing to protect or aesthetically conceal the placement underwater. The use of this device and system to supplement carbon dioxide in water will span many industries and applications. It will assist with mosquito trapping. It will also supplement CO.sub.2 in underwater growing environments.

An aquaculture system can include stacked growth trays. Animals, such as shrimp, can be transferred between the growth trays for different stages of growth. Waste water can be removed from the growth trays and can be processed by a water treatment system. Treated water can be returned to the growth trays. A valve in a first configuration can permit water to circulate through the growth tray, while impeding the animals from exiting the growth tray. In a second configuration, the valve can permit the animals to exit the growth tray, such as for transition to a subsequent growth tray. A sweeper system can be used for cleaning and/or mixing the water in the growth tray, and/or for pushing the animals out of the growth tray during a transition.

There is a modular, insulated, all-in-one, plug-and-play (MIAP) aquaponics unit that includes a framework having a single base and plural walls; an aquaculture tank defined by a first portion of the single base and a first set of the plural walls; a clarifier tank defined by a second portion of the single base and a second set of the plural walls; a bio-reactor tank defined by a third portion of the single base and a third set of the plural walls; a hydroponics tank defined by a fourth portion of the single base and a fourth set of the plural walls; and piping extending through the plural walls between each two adjacent tanks for allowing water from the aquaculture tank to flow into the clarifier tank and then into the bio-reactor tank and then into the hydroponics tank and back to the aquaculture tank.

A fish tank air hose channel apparatus for channeling and hiding air hoses includes a triangular top housing having a hose aperture extending through a pair of back walls. A pair of clips is coupled to the top housing is configured to engage a rim of a fish tank. A top end of a shaft is coupled to a bottom wall of the top housing around a shaft aperture extending therethrough. A bottom end of the shaft is coupled around an entry aperture extending through a rear face of a base. The base has a plurality of exit apertures extending through a front face to the entry aperture. The apparatus is configured to receive a plurality of air hoses fed through the hose aperture, into the shaft aperture, through the shaft, into the entry aperture of the base and out the plurality of exit apertures.

An aquarium or terrarium (7) with a gravel and/or sand layer (6) arranged in the aquarium or terrarium (7), at least having a base element (4) which is arranged at a distance from the base of the aquarium or terrarium (7). The at least one base element (4) is used as a support for the sand and/or gravel layer (6) in that the sand and/or gravel is rigidly connected to the respective base element (4).

A method of increasing oxygen levels in aquaculture involves pumping water from a body of water into a temporary holding tank and storing air under pressure in a storage vessel. The method involves enriching a stream of pressurized air from the air storage vessel by the introduction of oxygen from a downstream source of oxygen and directing the oxygen enriched stream of pressurized air into water drawn from the temporary water holding tank. The method then involves passing the oxygen enriched stream of pressurized air and water through at least one mixer, whereby a mixing of the oxygen enriched stream of air into the water occurs to create oxygenated water. The oxygenated water in then introduced into water used for aquaculture at an aquaculture facility.

An apparatus for generating nanobubbles for use with fluid dispensing fittings is described. The apparatus includes a longitudinal shaft having a first end portion, a body and a second end portion. The first end portion and the second end portion are adapted for connection with the body. The first end portion and the second end portion each includes a conical-shaped guide wherein the body comprises airfoil-shaped projecting members arranged circumferentially on the outer circumferential surface of the body.
