Abstract
It has been known for a long time that many fishes produce sounds especially during reproduction. Recent studies using a novel system for synchronous audio and video recordings underwater reveal that several species produce species specific and behavior specific sounds exclusively associated with courtship and the mating act. Passive acoustic technology can utilize these sounds to remotely monitor the breeding behavior of reef fishes. This application is being tested as an alternative or supplement to the traditional methods involving sampling fish gonads, ichthyoplankton net collection, and direct observation by scuba diving. This presentation will show a video with sounds of fishes courting and spawning and will describe their acoustic characteristics.
