This report explores potential utilisation of Calanus finmarchicus and krill in Nordic waters. Both are key zooplankton species that play vital ecological and economic roles in the marine ecosystems. The report therefore highlights their importance in supporting marine food webs, contributing to carbon sequestration, and offering potential applications in food production, pharmaceuticals, and aquaculture. The report identifies key challenges to sustainable harvesting, including ecological risks, technological constraints, and the need for regulatory oversight. It also highlights opportunities for innovation through technological advancements, market expansion, and regional collaboration among Nordic countries. Recommendations focus on fostering research and development, harmonising regulatory frameworks, and engaging stakeholders to ensure long-term sustainability. By addressing these aspects, the report aims to support informed decision-making and promote the development of Calanus and krill fisheries as part of a broader strategy for sustainable ocean resource management in the Nordic region. The report is an outcome of an AG fisk supported networking project aiming to facilitate networking and sharing of knowledge among different Nordic stakeholders on utilisation of Calanus and Krill. Much of the information presented in the report originates from a workshop held by the project, in Copenhagen on May 15th 2024.
