A peristaltic pump is provided for conveying a fluid pumping medium through a compressible hose. The pump is designed particularly for use in an aquarium, terrarium, or vivarium for metering fluids accurately and reliably by eliminating permanent tubing deformation and random stopping positions of rollers.

A circulating water purification system for aquaculture breeding, including a feeding machine, a growing pond, a water purification and separation system, and a recycling device, where the feeding machine for feeding fry to the growing pond is disposed outside the growing pond, the upper part of the growing pond is provided with a water-level safety line, the bottom of the growing pond is conical, and a mesh for filtering solids from liquids are mounted at the bottom of the growing pond; the bottom of the growing pond is connected to the water purification and separation system through a first discharge pipe; the water purification and separation system are provided with a feed pump, and pumps water to the growing pond through the feed pump; and the water purification and separation system are connected to the recycling device.

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.

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.

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.

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.

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.

A fluid pump assembly is used in combination with a container having a wall. The pump assembly comprises a first casing disposed outside the container in contact with the wall, a first magnetic assembly mounted to the first casing and operatively associated with a drive motor, a second casing disposed inside the container in contact with the wall, and a second magnetic assembly mounted to the second casing and operatively associated with an propeller. The first magnetic assembly includes a rotatable magnetic drive member drivingly coupled to the drive motor. The magnetic drive member is magnetically coupled to the magnetic driven member through the wall for imparting a rotary driving force of the drive motor to the propeller. Furthermore, the second casing is detachably connected to the second side of the wall of the container solely by magnetic attraction force between the first and second magnetic assemblies.

A fluid pump assembly is provided. The pump has a pair of units magnetically coupled to each other. The first unit contains a drive motor and a magnetic assembly. The second unit contains a magnetic assembly and a blade of a propeller/impeller for imparting movement to a fluid. As the first unit is activated by the drive motor, a magnetic flux is created which in turn rotates the magnetic assembly in the second unit, driving the blade.
