Fraunhofer Research Institution for Marine Biotechnology Paul-Ehrlich-Str. 1-3, 23562 Lübeck, Germany stephanie.borchardt@emb.fraunhofer.de Former studies showed that Integrated Multi Trophic Aquaculture (IMTA) concepts can be suitable alternatives to conventional indoor land based Recirculating Aquaculture Systems (RAS). The Nordic Network on Recirculating Aquaculture Systems is a lasting network, and everybody with an interest in RAS is most welcome to join (please refer to our website: NordicRAS.net). The network was founded in 2011 with support from the Nordic Council of Ministers. The steering committee consists of country representatives from Denmark, recirculating aquaculture systems (ras; also known as "closed-containment systems") are an emerging method of fish production which, due to their contained nature, have the potential to mitigate or eliminate many of the environmental concerns associated with more "open" other aquaculture production systems (e.g., net pens, ponds, flow-through … 1. Introduction. Land-based recirculating aquaculture systems (RAS) are becoming a viable alternative to traditional aquaculture methods, as they intensify fish production in advanced and controlled environments (Aguilar-Alarcón et al., 2020; Lazado and Good, 2021).The benefits offered by RAS are in terms of reduced water usage, controlled water quality, and improved biosecurity and disease Land-based farming of Atlantic salmon is projected to produce 100,000 tons of fish in 2023 and 320,000 tons in 2028. Assuming a typical 4 kg harvest size, 50 million eyed eggs available via import from overseas or domestic seed production will be needed on a year-round basis to produce 100,000 tons annually. This white paper will present a brief overview of the status of each of the various land-based aquaculture production technologies and the opportunities and challenges of each type. In addition, recommended research needs to address those opportunities with emphasis on facilitating economic development will also be provided. POND PRODUCTION SYSTEMS 2003.

Recirculating systems provide an alternative produc-tion method when temperature, salinity, disease, water supply, land availability, or exotic species /environmental regulations prevent more cost effective alternatives. A recirculating aquaculture system (RAS) can also be used to support traditional pond or net pen culture through aquaculture system (RAS) recycles 98% of the water needed for fish growing.
