Can certain metals repel sharks from fishing gear?
Date:4/22/2008

The lab experiments were conducted at the Virginia Institute of Marine Science using juvenile sand sharks up to five years old caught in surrounding waters and brought to an outdoor holding tank.

In addition to Brill, the study included scientists and students from Indiana University, Bangor University in Wales, Hampton University in Virginia, the University of Hawaii, and the research firm Shark Defense LLC of Oak Ridge, NJ, which develops shark repellents. Principal funding was provided by the Pacific Islands Fisheries Science Center of NOAAs National Marine Fisheries Service in Honolulu, with logistical support from the VIMS Eastern Shore Laboratory.

This study by Brill and colleagues is among the first to rigorously test the use of rare earth materials on repelling elasmobranchs, and supports a recent study using metal alloys to repel spiny dogfish conducted by NOAA researchers in Oregon.

Results of the sandbar shark study were presented at a NOAA-sponsored shark deterrent workshop in Boston earlier this month.
