Passive Acoustic Reflectors (PARs) Progress Report – March 2025

Click here for the March 2025 progress report on Passive Acoustic Reflectors (PARs), which:

1. Presents the results of a robustness trial, where PARs were tested in real fishing conditions to assess durability and practicality at sea.
2. Outlines a proposed methodology for a fishery-independent behavioural trial to evaluate cetacean responses to the PARs, which was ultimately rejected due to identified limitations.
3. Explores alternative next steps, including further design refinements, controlled acoustic testing, and evaluation in fishery-independent and fishery-dependent trials.
