A What happened
The UPAC-360°, a new underwater acoustic camera, has successfully recorded and identified sounds from 46 fish species in their natural environments, marking a significant advancement in bioacoustic research. This device allows for the extraction of individual fish sounds from complex underwater audio recordings, enabling researchers to map fish populations and behaviors. The study, conducted in Curaçao, revealed that less than 3% of the estimated 35,000 fish species have been documented in terms of sound. The camera's ability to isolate sounds and correlate them with video footage provides valuable insights into fish ecology and conservation efforts. However, limitations exist, such as depth restrictions and the need for sunlight for video recording.
