Experts are warning that EDF’s plans to replace a proven Acoustic Fish Deterrent with a high-frequency battery-powered device at Hinkley Point C will not protect all species or deliver long-term reliability. An eight-year delay has Read more…
The UK government has announced that Sizewell C is to become the latest in the UK’s new generation of nuclear power stations. The manufacturing cost has been estimated at £14.5bn for the first four years, Read more…
Fish Guidance Systems have produced high-quality technology that stops fish from going places they shouldn’t for over thirty years. Fish love to go places they shouldn’t – inside the intakes of power plants, clogging them Read more…
Our systems can be used to discourage managed fish stocks in lakes and reservoirs from exiting via outlet channels, as well as blocking invasive species such as bighead, silver, black and grass carp from travelling upstream.
Guidance is often necessary to affect the movement of migratory fish, which might otherwise enter channels and follow routes that are harmful.
These solutions can be deployed from a barge or boat in both freshwater and estuarine environments, with equipment moved to different locations as the project progresses.
Invasive species such as bighead, silver, black and grass carp pose a major threat to the ecosystems in which they are allowed to thrive.
Sound-based systems reduce the possibility of harm to salmon, without risking shutdown of facilities or incurring the high maintenance costs associated with operating fixed smolt screens
Eels have poor hearing ability, so sound-based systems are rarely effective in controlling their movement. Instead, FGS has developed light-based solutions that ensure these species are guided away from intakes
Gizzard shad, alewife and blue-back herring and more achieving deflection rates of over 95%
Every species of fish has slightly different physiology and hearing characteristics, we use three categories of hearing sensitivity before developing an appropriate solution.
