Movement of Depredating Species 

This aspect of research will aim to tag sharks species at an area with frequent depredation to see if sharks are staying at certain sites to depredate catch or moving broadly and only depredating catches opportunistically.  Testing will be carried out at several popular fishing locations in North, Central and Southern Queensland.  At these sites, vessel activity will be monitored to see if depredation hotspots correlate with the number of sharks present at a certain location. This research is vital to inform fishers on how they can best minimise depredation occurring while they are out fishing.
