1 Aug - 31 Aug 2017

Report period: 1 August - 31 August 2017

In addition to Ballina-Lennox Head and Evans Head (which have been operating since 8 December 2016), two new locations, Coffs Harbour and Forster each with ten SMART drumlines deployed daily, started on 14 August 2017.

During the month of August, SMART drumlines were deployed for totals of 21, 28, 12, and 16 days at Ballina-Lennox Head, Evans Head, Coffs Harbour and Forster, respectively. The average number of hours that SMART drumlines were deployed at each location was similar (8:21h to 9:01h), but varied daily depending on environmental conditions (4:53h to 10:51h).

Total catches

A total of 30 target sharks were caught in August; five White Sharks at Ballina-Lennox Head, 9 White Sharks at Evans Head, and 16, White Sharks at Forster (11 males and 19 females). No target sharks were caught at Coffs Harbour (Table 1).

Eight non-target species were caught; four Greynurse Sharks (two each at Ballina-Lennox Head and Evans Head), three Dusky Whaler Sharks at Coffs Harbour, and one unidentified Thresher Shark (Table 1).

Six alerts had no catch with the bait fully intact on four hooks and either 25% or no bait remaining on the other two hook when the contractor arrived.
