Dolphin Dissuasive Devices (DDD) are thought to limit interactions between dolphins and fishing nets by emitting high frequency ultrasound signals. Signals can be modulated (in length and width) to limit the potential of dolphins adapting to the signal. DDDs are currently used in the deepwater jack mackerel fishery (two units deployed either on bridles facing backwards over the net or placed on the headline getting coverage immediately in front of the trawl mouth). Currently there is anecdotal evidence that shows that these devices may be effective but little quantitative research to support this.
This desk-based study would involve an international review of Dolphin Dissuasive Devices with a focus on research on species and fisheries relevant to New Zealand. It would also involve developing a proposed methodology for field trials and assessment of a dolphin deterrent device in an inshore setting plus recommendations on location(s) and technology suited to the New Zealand inshore environment and dolphin species.
