Report period: 8 Dec 2016 - 7 Jan 2017

During the first month (8 December 2016 – 7 January 2017) of the NSW North Coast Shark Meshing Trial, SMART drumlines were also deployed on 27 and 29 days at Evans Head and Ballina-Lennox Head, respectively (Table 1). The mean number of hours that SMART drumlines were deployed at each location was similar but varied daily depending on ocean conditions (Table 1).

Twenty two (22) alerts were recorded from the SMART drumlines. These included nine (9) alerts with no catch, and 13 sharks comprised of nine (9) White Sharks, two (2) Tiger Sharks and two (2) Greynurse Sharks. All 13 sharks were deemed to be in good health and were released alive (Tables 2 and 3). After capture, sharks were relocated if conditions allowed. Data indicates that sharks depart the area following capture.
