SMART Drumline Catch Report
During April 2021, 10 SMART drumlines (SDL) were deployed during daylight hours for 23 days across the Gracetown SMART drumline fishing zone. Weather permitting, SMART drumlines are deployed and retrieved each day. However, adverse weather conditions prevented the setting of SDLs for seven days.
During April 2021, no target species (white sharks) were caught. A total of 13 non-target sharks were caught, along with one other non-target species. All sharks were tagged and released and there were no recaptures recorded. A Shortfin Mako “spat” the hook prior to being brought alongside the vessel and as a result, full catch details could not be recorded. Full details are listed in the table below.
During April 2021 SMART buoys were activated 42 times, with an average response time of 9 minutes. The maximum response time of 30 minutes from alert via the SDL to arrival of the vessel at the SDL was not exceeded on any occasion.
