There … Ten SMART drumlines are deployed evenly across 11.5 kilometres of coastline in the State’s South West, about 500 metres offshore from Hangmans surfbreak north of Gracetown to Ellensbrook in the south.

The Government has supported a variety of research projects and initiatives to enhance our understanding of shark biology and ecology to better inform our government policies. *No target species caught in the eight days of fishing operations in February 2019.
During the first 12 months, the SMART drumline trial caught two white sharks (target species) and 146 non-target sharks including tiger, bronze whaler, shortfin mako, dusky and smooth hammerhead sharks. Additional information about the activation of the shark warning systems can be found here. As part of the consultation process for the SMART drumline trial, the community was able to provide advice on potential locations for three additional satellite-linked (VR4G) acoustic receivers which were deployed, two outside Cowaramup Bay and one at Lefthanders surfing spot.

A SMART drumline is designed to be non-lethal and to send an alert when a shark has been captured on the line.

During the eight days of fishing operations in February 2019, no target species (white sharks) were caught.
SMART Drumlines: Shark Management Alert in Real Time NSW is leading the world in trials of SMART Drumlines, which are both a shark mitigation tool and a research tool that reduce the risk of interactions with sharks while minimising the impact on marine species. Weather permitting, SMART drumlines are deployed and retrieved each day. 139. The trial commenced on 21 February 2019 in the Gracetown area, in the State’s South West. On Réunionregular operation of "SMART" (Shark-Management-Alert-in-Real-Time) drum lines began in August 2015 and they are used in conjunction with bottom long lines. This extension will provide more data on the sharks being caught, tagged and monitored and will enable a science-based assessment on the effectiveness of the technology. Read more, Latest shark advice and warnings. Shark warning systems have been installed at nine locations in the SMART drumline trial area for the duration of the trial, alerting beach users of shark activity in the area. As the trial commenced on 21 February 2019, the February report only reflects the first eight days of operations. SMART drumlines are new technology that allow target sharks to be intercepted beyond the surf break; once caught, they are tagged and relocated 1km offshore. Switch on your Sea Sense. Weather permitting, SMART drumlines are deployed and retrieved each day, during daylight hours. The intent of the trial is not to kill sharks, but to catch, tag, relocate and release white sharks one kilometre from shore. Six non-target species of sharks were caught, along with two other non-target species. Weather permitting, SMART drumlines are deployed and retrieved each day, during daylight hours.
Future reports will reflect a full month of operations. In Reunion, fishermen usually attend the drum lines within 90 minutes of an alert and 90 per cent of animals caught on the hooks survive. SMART drumlines comprise of an anchor and rope, two buoys, and a satellite-linked communications unit which is attached to a trace and baited hook. The maximum response time of 30 minutes from alert, via the SDL, to arrival of the vessel at the SDL was exceeded on one occasion.
The Chief Scientist, will continue in his role and provide an independent assessment on the effectiveness of the SMART drumlines in reducing the risk of shark attacks. This was due to two sharks being captured on drumlines at the same time (23 February) at either end of the SMART drumline zone. SMART drumlines are deployed around 500 m offshore in 8–15 m of water, away from swimmers and surfers to allow sharks to be intercepted beyond the surf zone.
Operation Summary During February 2019, 10 SMART drumlines (SDL) were deployed during daylight hours for eight days across the Gracetown SMART drumline fishing zone. The drumlines are continuously monitored while in the water and positioned to allow a vessel to attend within 30 minutes of an alert being received. Read More. %PDF-1.6

A "SMART" drum line is based on the traditional drum line design, but it includes technology that can alert rangers to the capture of marine life, who can then attend the device if sea conditions permit. © All contents copyright Government of Western Australia. These receivers will provide ocean users and land managers with near real-time alerts through the Shark Monitoring Network when tagged sharks are detected. While they’d been in use for decades on metro beaches and proved highly successful in preventing attacks (depending where you sit on the correlation/causality spectrum) they also successfully caught pretty much … endstream
