Launched in 1994, the International Symposium on Ecohydraulics (ISE) provides a platform for scientists and engineers worldwide to discuss cutting-edge scientific progress, compare and evaluate state-of-the-art technical methods, and recommend them to the end-users. Dating back to 2011, the annual Fish Passage Conference has brought together experts, managers, stakeholders and companies from around the world with concurrent sessions in engineering, biology, and management and social issues. The joint ISE – Fish Passage 2024 conference will be held in Québec City, Canada. This event aims at increasing research and professional networking and is an excellent opportunity to connect future partners.
