Researchers from the Age and Growth Section conduct training in otolith chemistry.
December 9th, 2024Between September and December 2024, researchers from the Age and Growth Section have participated in the training course “Use of otolith chemistry in fish ecology: theory and practice” taught by Dr. Edwin Niklitschek, professor at the University of Los Lagos and researcher at the marine research center (i~mar), together with the collaboration of Dr. Pamela Toledo from the same university. This training included theoretical and practical sessions, which addressed concepts and theoretical foundations that support the application of chemical analysis of otoliths, its main methods and applications in fish ecology studies such as: identification of demographic units, estimation of population mixing, habitat reconstruction, migrations, life cycle, etc. The practical courses included modules on sample preparation for elemental and isotopic analysis, and a visit to the Mass Spectrometry Laboratory of the Department of Geophysics at the University of Chile, directed by Dr. Fernando Barra, and to the Isotopic Analysis Laboratory at the Andrés Bello University, directed by Dr. Sebastián Klarian.
Dr. Francisco Cerna Troncoso, head of the Age and Growth Section at IFOP, indicated that this training has been highly beneficial for our team of researchers, because it has allowed us to acquire the knowledge and methodologies in the use of metals and stable isotopes present in fish otoliths, to undertake studies aimed at understanding ecological aspects and the dynamics of exploited marine populations, knowledge that is essential for the evaluation and sustainable management of our resources.
