An aquaculture system (1) for farming aquatic organisms includes an apparatus (2) for supplying oxygenated water into an enclosure (20) in which aquatic organisms are to be fanned. The apparatus (2) includes a water inlet (4) and an oxygen inlet (6) to create a water and oxygen mixture. The apparatus (2) also includes a venturi (17) arranged to dissolve the oxygen into the water passing through the venturi and such that the oxygen and water mixture passing through the venturi (17) is exposed to a substantially null magnetic field. The apparatus is also arranged such that the water and oxygen mixture that is supplied to the venturi (17) contains substantially no colloidal minerals. The apparatus also includes an outlet (18) for the oxygenated water in fluid communication with, and downstream of, the venturi (17) and in fluid communication with the inlet of the enclosure (20).

An embodiment of the present invention makes it possible to sterilize a marine animal with use of sea water and atmospheric air, to the extent that the marine animal can be eaten as an unheated food product. A sterilization method in accordance with an embodiment of the present invention is a method for sterilizing a marine animal as an unheated food product, the method comprising the steps of: producing oxygen-enriched water by mixing electrolyzed atmospheric air into sea water; producing sterilizing water by electrolyzing the oxygen-enriched water; and bringing the marine animal into contact with the sterilizing water, the sterilizing water containing HOCl, OH.sup.− and O.sup.−.

A magnetization purifying device is provided. At least one or more accommodation spaces formed inside a housing unit along a preset depth or a width status are formed for accommodating a preset amount of magnetization purifying devices having corresponding status, a covering unit having an outwardly-extended engaging segment is provided and capable of being rotated for being matched with an opening formed at one end of the housing unit, another end of the housing unit capable of accommodating the magnetization purifying devices is formed with a recessed engaging segment, so that the magnetization purifying device can perform a predetermined rapid circulating magnetic force line cutting operation to introduced water or air, thereby enabling the water or air fully magnetized and discharged to be provided with anticipated pure oxygen and negative ions, thus the dissolved oxygen in water in a predetermined route, for example an aquaculture pond, can be increased.

The disclosure provides an outdoor device for simulating a pond ecosystem comprising a plurality of simulated ponds connected together by pipelines and including an adjusting pool, a plurality of control groups and a plurality of treatment groups with different concentrations; the plurality of control groups and the treatment groups are randomly distributed in the ponds according to a random draw method or a random allocation method, and the adjusting pool is a transfer station for water inlets and outlets of the ponds. According to the device, the plurality of control groups and treatment groups are arranged in a system, achieving a scale of a middle-scale pond ecological simulation system, which can stimulate an actual complex hydrostatic ecological system including a plurality of aquatic macrophytes, algae, zooplankton, benthos and microorganisms, and evaluate the effects of the complex ecological efficiency caused by chemical pollutants entering an actual water body.

A fluid-dynamic pump which is suitable for circulating water in an aquarium includes a rotary device, an electric motor configured to move the rotary device, a pump body which houses a printed circuit board which that controls the electric motor and a temperature sensor that detects the temperature of the water of the aquarium. The temperature sensor is positioned on the pump body.

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.

An integrated coral cultivation system includes a water tank unit having at least one aquaculture tank configured to contain corals, a water supply unit for supplying aquaculture water to the water tank unit, a drain unit for discharging the aquaculture water in the water supply unit and the aquaculture tank to the outside, an air supply unit for supplying air to the water tank unit, a temperature adjustment unit for adjusting the temperature of the aquaculture water in the water tank unit, a light unit for providing lighting to the water tank unit, and a power source unit for supplying power to the water supply unit, the air supply unit, the temperature adjustment unit and the light unit.

The invention relates to a method for controlling a concentration of dissolved oxygen in a volume (V) of water (W), wherein a device (1) for dissolving oxygen in water (W) is submerged in said volume (V) of water, wherein oxygen is injected by the device (1) with an adjustable flow rate into a main water stream (W′) sucked into a housing (100) of the device (1), and wherein the oxygen enriched main water stream (W′) is discharged by the device (1) out of the housing (100) of the device (1) into said volume (V) of water (W), and wherein a current concentration of oxygen dissolved in the sucked main water stream (W′) is measured with an oxygen probe (6) that is integrated into the housing (100) of the device (1), wherein said current concentration of dissolved oxygen is transmitted in a wireless fashion to a hand-held device (9) of an operator, and wherein the flow rate of the injected oxygen is controlled such that the measured current concentration of dissolved oxygen approaches a pre-defined reference value.

The present invention relates to a system and a method of manufacturing a feed product for farmed animals in an aquaculture environment, including but not limited to fish, shrimps, and crabs. The method of manufacturing the aquaculture feed comprising the steps of providing and contacting water, a fatty acid component, a protein source, and a feed stabiliser, and a suspension is formed. The feed stabiliser has a setting condition represented by a setting component. The feed stabiliser is contacted with the water at an activation condition, and the concentration of the setting component in the shaped suspension is increased to the setting condition of the feed stabiliser to obtain the aquaculture feed.
