What does Rising Tide BioAcoustics do?

Rising Tide BioAcoustics provides underwater acoustic solutions for:

fish deterrence and guidance

environmental monitoring

environmentally friendly methods of improving the efficiency and reducing bycatch of commercial fishing operations.

control/eradication of invasive species.

Our acoustic technology can reduce the environmental impact and operating costs of various activities, such as power generation, waterway management, commercial fishing and aquaculture. 

Sound as a fish deterrent for dolphins
Underwater sound as a fish attractor for fishes
Underwater sound monitoring as a tool for environmental monitoring

Environmentally friendly approach to fishing

In conjunction with our commercial fishing partner Katchi and the Higgs Lab at the University of Windsor, we are developing methods of reducing bycatch and increasing catch rates using very low-frequency sound. 

Fish behavioral responses using very low frequency sound

Did you know that most fish hear in the 0-3,000 Hz band and have the highest sensitivity in the very low frequency (VLF) band of 20-500 Hz? Fishes and other marine organisms can be deterred, guided and, in some instances, attracted by the particle motion and some VLF sound produced by our C-BASS transducers. Applications include deterring fish from entering turbines and water intakes and controlling invasive species in waterways.

Our fish guidance and deterrence solutions will use a game-changing family of very low-frequency underwater sound projectors that can produce sound at frequencies as low as 1 Hz called C-BASS.

C-BASS was originally developed as an environmentally friendly alternative for marine seismic surveys. Until recently, the use of VLF sound for many underwater applications has been prohibitive due to the size, cost and reliability of the transducer/speaker. C-BASS was developed by our partner company GeoSpectrum Technologies. They are literally an order of magnitude smaller than the previous state of the art and can produce high sound pressure levels between 1 – 1,000 Hz.

Hardware solutions for bioacoustics researchers

For bioacoustics researchers, C-BASS is an ideal solution for emulating anthropomorphic sounds and those made by marine fauna. We can also supply particle motion sensors to support your research and for environmental monitoring at installations such as offshore wind farms.

We can also supply
– hydrophones and passive acoustic monitoring arrays for detecting marine mammals and other marine species and measuring anthropomorphic sounds

– a wide variety of acoustic sound projectors as indicated below

Rising Tide Bioacoustics sound projectors and the frequencies they can work at.

Development programs are also underway for other applications, such as using very low-frequency sound for controlling zebra mussels and active noise cancellation for man-made underwater sound with the initial focus on vessel noise.

Rising Tide BioAcoustics partnership with GeoSpectrum

Rising Tide BioAcoustics has agreed with GeoSpectrum Technologies to commercialize its products for environmental and commercial applications.

We have access to GeoSpectrum’s acoustic performance modelling and transducer design software if your application requires a customized solution.
