Otoliths are calcareous structures that allow us to determine age, migratory patterns, micro-evolutionary and ecological changes of fish populations in the interaction with their habitat, being a fundamental piece of information in the evaluation of fish stocks and the impact of climatic change. on their populations.

Between October 9th and 13th, the Seventh International Otolith Symposium will be held in Chile, an event that brings together the world’s scientific leaders who carry out otoliths and other calcified structures of aquatic organisms research. These structures have the capacity to record populations age, migratory patterns, microevolutionary and ecological changes and the relationship with their habitat, which has led to various applications, both in the field of fishery resource management and in approaches to reconstruction of Past events and their relationship with the life cycle of fish and invertebrates.

This event has been held six previous times: 1st South Carolina, USA (1993), 2nd Bergen, Norway (1998), 3rd Townsville, Australia (2004), 4th Monterey, USA, 5th ° Mallorca, Spain (2014) and 6° Keelung, Taiwan (2018). The 7th International Otolith Symposium (IOS), which will take place between October 9 and 13, 2023 in Viña del Mar, will allow the scientific development of this discipline to be promoted from Chile to Central and South America.

This symposium, organized jointly between Fisheries Development Institute (IFOP) and the Pontificia Universidad Catolica deValparaíso (PUCV), will feature the participation of academics, researchers and postgraduate students from 44 countries from all continents. It will also have the presence of international experts who will offer 6 keynote lectures and 4 workshops to enhance methodological aspects. To organize this event, an Organizing Committee was formed made up of Chilean and Latin American researchers with experience in otolith science. The main conveners of this event are doctors Francisco Cerna Troncoso and Guido Plaza Pasten from the IFOP and PUCV, respectively, who have stated that the seventh IOS will provide an international forum for students and scientists from all continents to present their new research, discuss new potential applications, project future perspectives and expand your research networks.
