As part of the FishSenseWell project, a consortium comprising Fraunhofer IZFP and the Saarbrücken-based SEAWATER Cubes GmbH is conducting a study to provide an overview of all signal variables from recirculating aquaculture systems (RAS). Their aim here is to systematically search for additional, indirect measurement variables, find redundancies, reduce the number of sensors in the system and, as far as possible, replace expensive or complex measuring principles with simpler measurement variables.
