The present invention is directed to a first farming plant including a central tank and one or more surrounding tanks, where the central tank is used for water treatment and the one or more surrounding tanks are used for the farming of fish. The fish farming plan may also include one or more flow applicators, whereby the flow rate of the water in the surrounding tanks are individually independent of the water exchange rate. The fish farming plant may include several movable permeable section walls in each of the surrounding tanks dividing each surrounding tank into tank sections. Each surrounding tank is equipped with one or more outlets and one or two inlets, and a substantially horizontal/laminar flow structure of the water in each one of the surrounding tanks is provided.

Disclosed is a method for guiding aquatic organisms. The method includes disposing a plurality of electrode units at a distance from one another in water; and applying an electrical pulse to at least one electrode unit of the plurality of electrode units to generate an electric field and/or a magnetic field around the at least one electrode unit to guide the aquatic organisms by stimulating the aquatic organisms with the generated electric and/or magnetic fields.

A floating breakwater and wind energy integrated system used for offshore aquaculture. The system contains the wind turbine system, the floating breakwater system, and offshore aquaculture system. The combination of wind turbine, floating breakwater system and offshore aquaculture system makes full use of the floating breakwater, thus decrease the wave load on the floating cage. In addition, the floating breakwater offers a supporting platform to the floating wind turbine, which effectively reduces the costs of the wind turbine. Meanwhile, a power autarkic offshore aquaculture system may be realized by using the electrical energy generated by the turbine. Compared with the simple offshore aquaculture system, the utilization rate of the sea per unit becomes even higher while the costs of the floating wind turbine becomes even lower.

Provided is a system for centralized water monitoring of a fish farm. the system including a plurality of fish tanks divided into a first and a second subgroup; and a first sample conduit only connected to the first of the subgroups through a first set of pipe connections, and a second sample conduit connected only to the second of the subgroups through a second set of pipe connections; each one of the pipe connections being connected to only one fish tank; the pipe connections being configured for water sampling from a selected fish tank of the first subgroup into the first sample conduit and from a selected fish tank from the second subgroup into the second sample conduit. Water samples are received by a first and second sensor system from the first and second sample conduits for simultaneous measurements of the samples by the sensor system.
