The World Fisheries Congress 2021 will be delivered from Adelaide, South Australia by the World Council of Fisheries Societies, the Commonwealth and South Australian Governments and the Australian Society for Fish Biology. The Congress’ Steering and International Program Committees have developed the program, “Sharing the World’s Oceans and Rivers – a vision for the world’s fisheries”. Delegate access to the 2021 Congress has been affected by travel restrictions as a result of the COVID-19 pandemic, which has guided the program delivery format to become an interactive hybrid format. The Congress will be delivered in-person to New Zealand and Australian delegates and via an interactive virtual platform designed to accommodate the delivery of program sessions at convenient times for delegates around the world. The program features 1,400 presentations addressing sustainability matters;innovation in technology and policy;acknowledgement and discussion of the societal matters facing fisheries;new research and discoveries in fish and aquatic ecosystem management. © 2021 American Fisheries Society
