On behalf of the Symposium conveners, it is our great pleasure to welcome you to Viña del Mar, Chile for the 7th International Otolith Symposium (IOS).

The Series of International Otolith Symposium has travelled widely since 1993, and now we are delighted to host the 7th IOS in South America. The objective of this symposium is to know the scientific advances in otolith research and other calcified structures, as tools to address ecological and environmental problems in aquatic ecosystems and their resources.

The registration and abstract submission platform will be released by January 2023.
