In the project AquaInno (Ecologically compatible aquaculture using floating flow-/circulation systems) we tested novel floating flow-/circulation plants to address sustainable, ecosystem-friendly system designs. AquaInno was a joint project including partners from industry and research, within which ecologically functioning alternatives regarding the traditional fish farm cages were conducted. Our approach was to lower the ecological impact of inshore, nearshore, and offshore aquaculture facilities. The consortium were set-up within the framework of InnoNet - Promotion of innovative networks (Förderung von innovativen Netzwerken), consisted of specialists with regard to system design, synthetic material plant construction, electronics, environmental legislation, biology and applied aquaculture. In cooperation with the AWI (lead), the University of Applied Sciences Bremerhaven and the University of Rostock, a patent of the company Aquanova GmbH was further developed. The project AquaInno was financed both by the industry partners Aquanova GmbH, GMA Gesellschaft für Marine Aquakultur mbH, Fishery Müritz-Plau GmbH, Klävertec Sewage Plant Construction GmbH, OPTIMARE Sensor Systems AG, Peehs Plastics Construction, Sasol Wax GmbH. The project was financed by the Federal Ministry of Economics and Technology.
