Requirement

The UoC shall only use aquatic acoustic deterrence where scientific evidence suggests that it does not result in significant stress or injury to, or mortality of, the affected species or its population(s).

How Do I Interpret This Requirement?

  • Acoustic deterrence includes any device or method used in which acoustic (‘sound’/’noise’) is used to deter wildlife. This includes, but is not limited to, the use of acoustic deterrent devices (ADDs) and acoustic harassment devices (AHDs).

Evidence of Implementation

  • Records of the use of any aquatic acoustic deterrence, which includes the frequency and duration and duration of the deterrence.

  • If aquatic acoustic deterrence is used, scientific reports/publications are obtained which demonstrate that the deterrence does not result in significant stress, injuries to, or mortality of, the species impacted/targeted by the deterrence.

Auditors Should Confirm

  • Records are provided to demonstrate whether any aquatic acoustic deterrence has been used.

  • If aquatic acoustic deterrence has been used, scientific reports/publications have been presented by the UoC to demonstrate that the deterrence does not result in significant stress, injuries to, or mortality of, the species impacted/targeted by the deterrence.
