Bait Traps For Hagfish
The circular trap and bait bag have the
same cut-up fish contents, but the bait bag has much more fish
in it, acting as a "decoy" to lure hagfish and other
non-targeted species away from the traps. The traps
are intended to capture crabs for Dr. Tammy Frank's electrophysiological
vision experiments. Attached to the large ball on the
top of the bait bag is a "pinger," which emits a
sonar signal so it can be easily located for recovery by the
submersible. Video footage courtesy of Harbor Branch Oceanographic Institute.
