Comments:

More sharks than typical seasons in past, sharks were apparently abundant earlier than is typical and sharks appeared to remain longer than usual.

We hadn’t seen this many sharks since 1997-98 season.

We observed some sharks we are familiar with from our 1995-2003 efforts.

Still seeing more females than males.

We observed more sub-adults than is typical.

Deployed record number of tags this season.

DNA Samples shipped to US Fish and Wildlife, these will be shared with TOPP program associates.

The bait used during the 2005/06 effort was acquired from HMB whale stranding and ANI reserve.
