R02/0923 - Testing of acoustic tracking system for toothed whales around longline and gillnet fishing gear, and preliminary trials of depredation mitigation devices for longline fisheries

This study was intended as a Phase II extension component of the initial study on the depredation effects of toothed whales. This extension was to further assess the potential for depredation mitigation acoustic devices in Australian tropical tuna longline fisheries, and to continue development of methods for tracking toothed whales around longline gear as a means of achieving more appropriate experimental results to assess effectiveness.
