Abstract
Novel methods to use Ocean Sound to address ecological questions are increasingly being developed but require optimization and validation to ensure their reliability. Source validation, increasing the number of known soniferous species of marine fauna, and characterizing their acoustic repertoires are important components of this effort. Coral reefs are remarkably complex, diverse, and noisy environments, inhabited by many soniferous species, hindering the association of vocalizations with the emitting species. Damselfish (Pomacentridae) are common and conspicuous reef fishes that have been relatively well-studied due to their abundance, territorial behaviors, and sound production. Most fish sound studies support that fish vocalizations are species-specific, often showing niche acoustic partitioning to avoid competition across frequency and time. It is imperative to record fish vocalizations in the field to avoid distortion in their acoustic attributes, which then can be used for further analyses such as automated detections. Here, we characterize the vocalizations of Dascyllus aruanus and Dascyllus reticulatus using field-experimental settings for in situ recordings from the Ningaloo Coast and the Great Barrier Reef.
