Pond filter unit and a method for operating a pond filter unit (1). A control unit (12) controls the operation of the pond filter unit (1), including the cleaning cycle of the filter (2′, 2″, 2′″). The pond filter unit (1) further comprises one or more plugs (14) for connecting one or more auxiliary devices, such as a separate pump, one or more additional pond filter units, illumination devices/lamps, air pumps, and/or feed automats. The control unit (12) of the pond filter further controls the one or more auxiliary devices connected to the plugs (14), such as pumps, air pumps, automatic feeding devices based on input settings for each of the one or more auxiliary devices. The control unit (12) further controls the cleaning cycle for cleaning of the filter (2) in the vessel (3). The cleaning cycle comprises a sequence of backwash and/or a mechanical filter cleaning sequence where a filter cleaning motor unit (6) rotates the filter cleaning device (7) in the vessel. During backwash, the valve (8) directs the water to the waste water outlet (11). The filter unit allows to control the one or more auxiliary devices by the pond filter control unit (12), and to coordinate the control of the additional devices in relation to the control of the filter.

A system and method of sustainable aquaponics that vertically integrates unique aquaponic system designs with alternative aquaculture fish feed sources, fingerling production methods, alternative aquaculture/farmed fish grow out models, and green energy sources that yield organic produce in the form of fruits and vegetables. A raceway system serves as the hub for grow-out throughout the warm and cold months. During the summer months, fish can be spawned and fed for steady growth, while during the winter months, the fish continue to grow at slower quite acceptable growth rates. Plants like legal (licensed) cannabis for medical use can be grown in plant areas near the raceways with very high yields. The system may also be used to reclaim gray water using the biology of the system to purify it for agricultural use.

A multi-stage rationed feeder for ornamental fish, comprising a container, a container cover assembly and a measuring cup assembly. A falling-material receiving cover of the container cover assembly is adapted to a container cover, and a buckle position is buckled into a container cover snapping slot, such that the falling-material receiving cover is rotatably mounted and connected to the container cover. The measuring cup assembly comprises a measuring cup and a blocking slice. One end of the blocking slice is provided with a sleeve hole for sheathing a blocking slice pin. A pin groove is adapted to a falling-material receiving cover pin snapped into the pin groove such that the measuring cup assembly is removably mounted and connected to the container cover assembly from below.

The present invention relates to a control unit (116) for a game or fish feeder (100). The control unit (116) is mounted on the feeder (100) and comprises: means (130) for controlling the powering of a drive unit (110) of said feeder (100) for controlled output of feed from the feeder (100); a wireless transmitter (138) arranged to communicate over a wireless network (146) with a remote unit (140); a sensor (132; 134) for measuring a parameter of the feeder (100); and means (124) for determining whether a measured parameter value provided by said sensor (132; 134) fulfills a predetermined condition in order to detect an action-requiring state of the feeder (100). In response to a detected action-requiring state, the wireless transmitter (138) is triggered to send a notification to said remote unit (140).

An offshore farming system comprising an elongated vertical support column floating vertically in water with a larger extension below sea surface than above the sea surface, and a rigid cage structure enclosing the elongated vertical support column in circumferential direction and arranged movable in longitudinal direction of the elongated vertical support column.

A system and method for shrimp aquaculture is disclosed. All growth phases and essential operations are modularized and integrated in a system controlled by a cyber-physical platform. The system comprises one or more post-larvae nursery module(s), grow-out production module(s), recirculating aquaculture system (RAS) module(s), feed distribution module(s), and regulatory elements comprised of Program Logic Controllers (PLCs) integrated with Human Interface Modules (HIMs).

The disclosure relates to the technical field of aquaculture, and more particularly to a fish breeding device provided with a magnetizer and a method for accelerating normal propagation and growth speeds of fishes. The fish breeding device includes a box body, a controllable partition plate, an extraction pump, and the magnetizer; the controllable partition plate is arranged in the box body and used for dividing the inner space of the box body into a feeding area and a non-feeding area; the extraction pump is arranged on the controllable partition plate and used for exchanging the water body in the feeding area with the water body in the non-feeding area; the magnetizer is arranged on the outer wall of the box body corresponding to the feeding area, and used for magnetizing the water body of the feeding area. In the disclosure, fish eggs are further hatched by the magnetized water. An adjustable magnetic field is utilized to act on fishes in development so that the fishes normally propagate and grow without causing the problems of retarded embryo development, stagnation, deformity, and the like. Meanwhile, pollutants generated in a feeding process can be purified, the utilization rate of feed put in a breeding process is increased, intermittent magnetization is adopted, and the consumption of electric energy is reduced.
