SMART Drumline Catch Report

March 2021

Operation Summary

During March 2021, 10 SMART drumlines (SDL) were deployed during daylight hours for 30 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 on one day.

Catch Summary

During March 2021, no target species (white sharks) were caught. A total of 19 non-target sharks were caught, but no other non-target species were captured. All sharks were tagged and released, and there were two recaptures recorded. 

The two recaptured sharks were both Tiger Sharks, and were recaptured on 11 and 23 March 2021. The Tiger Shark captured on 11 March 2021 was originally caught on 15 November 2019, and was released in good condition. The Tiger Shark captured on 23 March 2021 was originally caught on 6 January 2021, and was tagged with PAT and acoustic tags and released in good condition. 

Full details are listed in the table below.
