Unrivalled expertise in fish guidance and deterrence

Fish Guidance Systems is the world’s leading designer and installer of sound and light-based fish deterrents.

We work with governments and private organisations across the globe, providing design, manufacturing, installation and maintenance services that are backed by over 25 years of innovative projects and groundbreaking research.

Our systems are tailored to particular species, including invasive carp, salmon and eels – controlling their movement with sound projector arrays, high intensity lights and other novel developments.

Only a scientific approach, combined with political will and collaboration between experts, can ensure the movement of fish is managed and supported effectively. The FGS process begins with a detailed analysis of the environment and your requirements. We then develop a unique design that accounts for individual species and the wider ecosystem.

Scientific expertise, regulatory compliance

Power generation, civil engineering and the introduction of invasive species such as bighead and silver carp affect the natural balance of the environment.

FGS is committed to maintaining this balance not only because it is often a regulatory requirement, but because it is the responsible thing to do. We have conducted extensive research and trials into the most effective deterrence and guidance techniques. This experience is supported by expertise in aquatic biology and acoustics, as well as electronic, electrical and mechanical engineering, and software development.

Acoustic and light-based behavioural systems are proven to be more effective than physical screens in cases where waterways need to remain navigable, and when fish need to be diverted from large volume flows where debris puts physical barriers at risk.

As fish protection needs and regulations evolve, so too have our systems. Each is backed by scientific evidence, and our continued investment in research and development means this body of evidence is ever-growing.
