An example aquatic imaging system comprises a light source, a first platform coupled with a image capture device and a second platform that is parallel to the platform, the image capture device having a first field of view, and, the second platform being coupled to a organism tank, first organism tank having an inner wall, outer wall and a base that defines a well capable of retaining water, the base being parallel to the second platform, the organism tank configured to receive a light beam originating from the light source and configured to project at least a portion of the light beam through the well and in a directional plane that is parallel to the base, the image capture device configured to direct the first field of view from the first platform through the well in the organism tank.

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.

A lighting device includes: a light emitting unit that emits illumination light; and a control unit that controls an intensity of the illumination light. The control unit controls the intensity of the illumination light in each of a period of no change during which the control unit keeps the intensity of the illumination light constant and a period of change during which the control unit changes the intensity of the illumination light as time passes. The period of no change is longer than the period of change.

An aquaculture system (Sy) includes mineral sensors (22, 24, 26) for detecting the concentrations of minerals contained in rearing water within a rearing tank (50) for rearing an aquatic organism or the rearing water within a circulation passage (70), and an adjustment section which performs instruction issuance or operation for rendering the concentrations of the minerals contained in the rearing water coincident with their standards when the mineral concentrations detected by the mineral sensors (22, 24, 26) deviate from their standards.
