The main objective of this project is to investigate the behavior of rocky reef fish species that structure an ecosystem, in relation to their acoustic and physical environment. This experimental, in situ approach will make it possible to identify how a fish community responds to external disturbances and to assess its level of resilience. Based on an acoustic tagging approach of individuals from 11 species, a series of analyses will be conducted to examine the individual, intra- and interspecific processes that influence rocky reef fish communities.
