Comments

When the contractors responded to nine alerts that had no catch, they found that three hooks had no bait remaining, one hook had 20% bait, and five hooks had 100% of the bait remaining.

All sharks triggered an alert to the DPI contractors who responded and were at the SMART drumline within an average of 25 minutes.
