Shark Repellent
Show notes
A shark repellent is any method of driving sharks away from an area. Shark repellents are a category of animal repellents. Shark repellents are of interest to the commercial fishing industry as well as to swimmers, surfers, and other people in the ocean. Shark repellent technologies include magnetic shark repellent, electropositive shark repellents, electric repellents, and semiochemicals. Some electric repellents may reduce shark interactions with bait by about half, depending on the product, the type of shark, and other factors;[1][2] the other types are not expected to have a significant protective effect for swimmers.[3]
