Report period: 8 May - 30 May 2017

During the sixth and final month (8 May 2017 – 30 May 2017) of the NSW North Coast Shark Meshing Trial, SMART drumlines were deployed for totals of 22 and 19 days (from 23) at Evans Head and Ballina-Lennox Head, respectively (Table 1). Similar to previous months, the mean number of hours that SMART drumlines were deployed at each location varied daily depending on ocean conditions, (Table 1). The mean number hours deployed was consistently longer at Evans Head (Table 1).

Nine alerts were recorded from the SMART drumlines. These included five White Sharks at Evans Head and two White Sharks and two alerts with no catch at Ballina (Table 2). There was no alert for the one Dusky Shark caught at Evans Head. This small animal (1.15 m total length) was found alive on the SMART drumline at the end of the day.
