The groundbreaking technology behind TAST reflects a deeper understanding of mammal behavior and leverages nearly 20 years of scientific research. In contrast to primitive, untargeted acoustic deterrent devices (ADD), GenusWave employs a narrow band of sound frequencies to trigger the “startle response” in mammals, such as seals. For our initial endeavor, this minimally disruptive approach allowed for protection of salmon in aquaculture environments without harming seal populations. Today, TAST can also deter marine mammals from potentially harmful interactions with fisheries, vessels, oil spills, and offshore development, and protect wild salmon from over-predation by pinnipeds at migration bottlenecks.
GenusWave was developed with the help of biologists from the world-renowned Sea Mammal Research Unit of the University of St Andrews in Scotland. We used rigorous research, not guesswork, to create the industry’s only safe, non-habituating, and target-specific solution to human-wildlife conflict around the globe.
At GenusWave, we know that human activity can negatively affect the natural world and that our industry must take steps to minimize its impact. We’re leading the way in research and development of technologies that protect animals and their habitats, allowing people and animals to peacefully coexist.
GenusWave works with governments, nonprofit organizations, and private enterprise to find solutions that support the fish farming industry with sustainable solutions. GenusWave’s technology represents a safer, more effective approach — and the only one backed by science.
GenusWave develops scientific solution that respect nature and harness nature ecosystems. Our goal is not to defeat nature – but to reconcile human activity with environmental imperatives. We offer solutions that respect nature forces, not oppose them.
We're leading the way in sound technology for the ocean and beyond. Explore some of our research projects and milestones.
TAST began through research by world-renowned scientists, Thomas Götz, Vincent M Janik, at the University of St. Andrews in Scotland, UK. Many years of trial and error uncovered new applications for the little studied auditory “startle reflex” in marine mammals.

Many years of study uncovered new applications for the little-studied auditory “startle reflex” in marine mammals, which caused sensitization in seals and caused them to avoid known food sources in favor of staying away from the sound.
Götz & Janik (2010)
TAST was recognized as an alternative to conventional ADDs that solved many of the problems with this original technology, including habituation, noise pollution, and hearing damage to target species.
Götz & Janik (2013)
The use of acoustic startle technology for mammals is patented by Thomas Götz and Vincent M Janik.
Further research with TAST finds that the target startle response can be highly specific depending on signal frequency and target species hearing sensitivity. Scientists were able to selectively deter seals without affecting harbor porpoises also in the study area.
Götz & Janik (2015)
TAST is explored as a way to protect prey from predators. When implemented on an aquaculture facility, it showed reductions in seal predation by over 90%.
Götz & Janik (2016)
Onsite research at Ballard Locks and Whatcom Creek. Applications explored for predation reduction on endangered salmonids in the Pacific Northwest. Studies saw 45-77% reductions in predations when carefully implemented at pinch points to migration.
Williams et al. (2020)
Startle reflex is explored in harbour porpoise. Research showed that by using a different signal, these species react with similar aversive behavior as seen in pinnipeds.
Hiley, Janik, & Götz (2021)
Lessons are learned about launching effective TAST deployments in riverine systems.
Williams et al. (2021)
Startle reflex is explored in orcas and humpback whales. Research showed that by using a different signal, killer whales react with similar aversive behavior as seen in pinnipeds. More research is needed to assess humpback whale response.
Langstein (2023)
This study examined predation of individual seals on endangered salmonids. Researchers modeled a 43.8% reduction in overall foraging success when TAST was in use.

In October 2024, GenusWave and the University of St Andrews were honoured with the Global Seafood Alliance’s Responsible Fisheries Innovation Award. This recognition reflects our dedication to innovation and sustainability, and highlights the effort, creativity, and teamwork of many collaborators who have been vital in developing this technology.
In a test at sea with an inshore static net fishery in England, researchers found a 74 % increase in catch weight in test nets compared to controls.

GenusWave is a science-based technology company driven by a deep respect for nature. This underlies all we do and guides the development of our signature products: unique systems that keep wild animals away from vital human activity — keeping animals safe and people productive. In achieving this goal, we provide benefits for the humans of today and the planet of tomorrow:
1.Harness science to solve human problems.
2.Support the planet's fragile environment in all we do.
3.Develop solutions that create jobs and build communities.
4.Draw inspiration from both natural wonders and scientific ingenuity.
5.Reconcile the needs of people and animals.
