Acoustic deterrent system

fishfor aquaculture

Our MMPA compliant, award-winning deterrents keep fish safe from predators without harming marine mammals. We combine acoustic and electric systems with thermal camera triggers to provide long term effectiveness and high welfare standards. It’s the best solution for responsible farming. Environmental benefits Safe for marine mammals Our randomly modulating computer generated sound frequencies avoid hearing damage and our low frequency RT1 system (0.8kHz – 2kHz) avoids hearing ranges of non-target cetacean species like porpoises and dolphins. To further reduce acoustic output we use a thermal trigger to activate deterrents only when the risk of a predator attack is high. Operational benefits Long term effectiveness You need a predator deterrent that won’t decrease in effectiveness over time due to predator deafness or habituation. Our CageGuard system of triggered acoustic and electric deterrents has been deployed on dozens of farm sites for years with no drop-off in impact due to habituation.
