The Fish-X Project is a technology and open-source project which aims at making the European Union fishery industry sustainable. It is a 3-year project and has been initiated and funded by the EU Horizon Europe Programme.The Fish-X Project is being implemented by seven European organisations, called consortium partners, including TransMarTech Schleswig-Holstein (TMT, Germany), EU Tech Chamber (EUTECH, Germany), Collecte Localisation Satellites (CLS, France), North.io (Germany), Sciaena (Portugal), OURZ (Germany), and WWF EPO (Belgium).The Fish-X Project is developing a Fisheries’ Dataspace (Fish-X) and an Insight Platform that is based on smart orchestrated architecture and open interoperable technology via Gaia-X. The dataspace and platform allow users to utilise the data for improved fishing methods, increased yields, and protected endangered fish species. Moreover, the project also targets streamlining the Monitoring, Control, and Surveillance (MCS) Processes to support the implementation of Common Fisheries Policies (CFP). The project also brings together different stakeholders such as large to small-scale fisheries, fishermen associations, regulators, relevant ministries, and decision-makers, to participate in the consultative process of developing and refining new technologies in view of the changes and revisions in CFP.
