The genus Salvelinus (charrs) contains the northernmost freshwater fish species on earth that also exhibits the most remarkable polymorphism of all vertebrates. Our knowledge and understanding of the evolution, ecology, and biology of charrs has increased greatly in recent decades, aided by growing research and development of new technologies. Climate change, impacts of non-native fishes, and restoration/conservation of charr species have become an international focus and sustainable management of all charr remains a major challenge, especially at the southern limits of their range.

This 9th International Charr Symposium will gather scientists with an interest in charr biology from the whole distribution of the genus, and will disseminate the latest research findings within a broad range of topics. The symposium will also provide a unique forum for networking and developing research collaborations. Our aim is to publish the proceedings of the symposium in a special issue of Hydrobiologia (impact factor 2.051). Additionally, selected sessions from the symposium will be used in a forthcoming book on the lake charr (S. namaycush).

The charr symposium series has a long history from its origins in Winnipeg, Canada in 1981 to locations around the northern hemisphere: Sapporo, Japan (1988), Trondheim, Norway (1994), Trois-Rivières, Canada (2000), Reykjavik, Iceland (2006), Stirling, Scotland (2009), Yuzhno-Sakhalinsk, Russia (2012), and Tromsø, Norway (2015). In 2018, the symposium will take place for the first time in the United States, in Duluth, Minnesota, on the shores of Lake Superior, where the lake charr and brook charr (S. fontinalis) thrive and have supported prosperous fisheries for centuries.

North America is home to more charr species than any other continent on earth, with three indigenous species, the lake charr, brook charr, and bull charr (S. confluentus), and two holarctic species, the Arctic char (S. alpinus) and Dolly Varden (S. malma). The only charr species not represented in North America are the white-spotted charr (S. leucomaenis) and the stone char of Kamchatka (scientific name unresolved). The 9th International Charr Symposium hopes to see research on all charr species!
