The European Aquaculture Technology and Innovation Platform (EATiP) and the Ocean Best Practices System (OBPS) of the Intergovernmental Oceanographic Commission (IOC) are jointly organizing a workshop to stimulate sharing of knowledge and to promote best practice development across aquaculture systems and regions in Europe. The aim to consolidate data sharing and best practices relates to a broad range of aquaculture areas such as spatial planning, animal health and welfare, traceability, environmental performance. The workshop will provide the participants with a better understanding of how to develop and maintain best practices within the existing boundaries for sharing of data. It will also show examples of how good practices at a local, regional or EU level can contribute to better aquaculture planning and control. It will also look into opportunities for guidance and collaborative actions on how to support best practices in aquaculture.
