A system is disclosed for protecting fish from parasite infection. The system comprises a fish guidance system for deterring fish from moving into a first region bordering a water surface and/or for can move from the second region into the first region so that they can reach the water surface bordering the first region. The system further comprises a radiation disinfection system that is configured to provide disinfection radiation to the first region, the disinfection radiation being configured to disinfect water from parasites.

System and method for protecting fish from parasite infection

The invention refers to an apparatus () for controlling a lighting system () comprising a plurality of lights (), wherein the lighting system is adapted to perform a hidden sensing, like radiofrequency sensing, in a sensing region (). The apparatus comprises a sensing activity information providing unit () adapted to provide sensing activity information indicative of a hidden sensing activity of the lighting system (), a notification mode selection unit () adapted to select a notification mode for notifying a person of the hidden sensing activity, wherein the selection is based on the provided sensing activity information and wherein each notification mode refers to a visual feedback, and a lighting system controlling unit () adapted to control at least two lights of the lighting system based on the selected notification mode to provide the visual feedback. The invention allows to notify a user of a hidden sensing.

Apparatus for controlling a lighting system

An aquaculture luminaire () generates below the water surface upward light () and downward light (). The upward light () is all directed with an angle to the vertical greater than a threshold angle. The division of light between the upward and downward directions may be configurable. Alternatively or additionally, the threshold angle may be configurable so that it ensures the light exceeds the angle for total internal reflection at the water surface. In this way, the luminaire is adaptable to the intended installation position of the luminaire and/or the prevailing water surface conditions (e.g. waves).
