An insulated passive house, building, or skyscrapers system and method with integrated aquaponics, greenhouse, and mushroom cultivation, includes a glazing on a sun facing side at an angle to maximize winter sunlight, and housing a fish tank; a plant growing area; a mushroom growing area; a shop, apartment or office area; a water wall thermal mass that divides the plant growing area from the mushroom growing and the shop, apartment or office areas, and the fish tank; and a natural air ventilation (NAV) system that provides misted air to the mushroom growing and the shop, apartment or office areas, and the fish tank from O2 generated by the plant growing area, and CO2 generated by the mushroom growing and the shop, apartment or office areas, and the fish tank to the plant growing area.

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.

The present invention relates to a movable aquaculture platform suitable for offshore onboard cabin culture and open culture. The aquaculture platform includes a hull with a propulsion system and an onboard control system. A recess recessed downwards based on a plane of a main deck is provided between the front and rear of the hull. Both sides of the recess are formed into an open structure corresponding to double sides of the hull. The recess is provided with a closed cage. The cage and the recess together constitute an open culture cabin. An internal space of the cage is used for culture. The hull is provided with a closed culture cabin below the recess. The present invention can flexibly switch between an onboard closed cabin culture mode, an onboard open cage culture mode and a mixed mode thereof according to different working conditions.

A Bluetooth, or other wireless communications protocol, control of a water filled habitat system. A Bluetooth phone application will control the duty cycle on a timed basis or programmed to maintain a desired oxygen saturation of the water based on the readings sensed by the oxygen sensor. The Bluetooth phone application will control the duty cycle on a timed basis or programmed to maintain a desired temperature of the water based on the readings sensed by the temperature sensor. On and off duty cycles will conserve on power supply life and reduce noise and extend the life of the environmental regulating device.

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 provided an inline saturator system and method for gas exchange with an aqueous-phase liquid. The system comprises a pressure vessel, configured to receive a first liquid and a first gas from external sources and to discharge a second liquid and a second gas from the pressure vessel, and a gas infusion device situated within the pressure vessel. The gas infusion device is configured to receive the first liquid and first gas, to facilitate gas exchange therebetween, producing the second liquid and the second gas, and to discharge the second liquid and second gas into the pressure vessel. The system further includes a recirculation system configured to direct a portion of liquid within the pressure vessel back into the saturator device, where injection of the redirected liquid into the gas infusion device forces the first liquid into the gas infusion device for the gas exchange.

A mort trap assembly includes an upper ramp with a top end, a first bottom end, and an outer edge that is fixedly attached to an inner edge of a slide. A retaining chamber is located below the upper ramp and includes a first entry port located below the first bottom end of the upper ramp. A lower ramp has a top end spaced away from the upper ramp, and a first bottom end located at a bottom of the first entry port of the retaining chamber, and a purge pipe fluidly connected to the retaining chamber. The upper ramp is configured to receive morts from the slide, and the lower ramp is configured to receive the morts from the upper ramp and to direct the received morts into the first entry port.

Systems and methods for intensive recirculating aquaculture are provided herein. An example system includes water sourced from a first segment of a saline aquifer, a recirculating aquaculture system receiving the sourced water and producing discharge water, and a water discharge point located within second segment of the saline aquifer disposed below the first segment of the saline aquifer.

An insulated passive house, building, or skyscrapers system and method with integrated aquaponics, greenhouse, and mushroom cultivation, includes a glazing on a sun facing side at an angle to maximize winter sunlight, and housing a fish tank; a plant growing area; a mushroom growing area; a shop, apartment or office area; a water wall thermal mass that divides the plant growing area from the mushroom growing and the shop, apartment or office areas, and the fish tank; and a natural air ventilation (NAV) system that provides misted air to the mushroom growing and the shop, apartment or office areas, and the fish tank from O2 generated by the plant growing area, and CO2 generated by the mushroom growing and the shop, apartment or office areas, and the fish tank to the plant growing area.
