AP has an article about a new shark repellent tested in the waters of Bimini. While visiting Dr. Samuel Gruber a few weeks ago, I saw demo footage that was very impressive indeed. One drop per minute into open water above a hang bait will keep all sharks away, and not only to sharks avoid the bait, they vacate the area altogether. A full squirt of the stuff will make sharks evacuate the area at high speed, staying away for a full 15 minutes.
The testing was done at BBFS, where I covered Gruber’s PIT Tagging program. The researchers are now planning on testing the repellent on larger sharks like great hammerheads and tigers. By the way, the photo in the AP article shows the repellent waking a shark up out of tonic immobility.
