SharkSafe Barrier: Net Free, Shark Free This barrier overwhelms sharks’ sensory system by stimulating their electro-receptors, and effective repellent that does not affect other bony fish and marine life. This means that demarcated areas of the sea can be kept shark free with a device that is not as inhumane or ecologically damaging as shark nets, drum lines or exclusion nets. Further, this innovation is more cost-effective than these other devices. Bring on the SharkSafe surf!
This innovation proposes a shark barrier comprising of multiple, preferably interconnected, elongated members extending from the sea floor to the sea surface. The magnets provided on the members exploit the sensitivity of the Ampullae of Lorenzini in sharks by over-stimulating their electro-sensory systems, while not affecting bony fish and other marine life. The market segments for this innovation include Municipalities, local government, marine environmentalists, and conservationists. The SharkSafe Barrier has shark conservation properties, but also reassures local and foreign sea swimmers and surfers, thus having a positive impact on tourism.
The SharkSafe members are capable of resisting oceanic tidal currents and therefore form an effective barrier which can be used to protect large areas. This invention is environmentally friendly: use of the barrier is not detrimental to sharks or other aquatic creatures.The materials used to construct the members allow for algae growth, a vital element in healthy marine ecosystems.
The combination of a thicket-like appearance of the members and the magnetic effect provided by the shark barrier enhances the efficacy of the barrier. The articulated member configurations allow slight movement as a result of oceanic currents, without causing an entire member to shift horizontally.This invention creates zero risk of animal entanglement.
