Aparte de los depredadores naturales, las redes de pesca y la contaminación, algunos peces corren el peligro de verse absorbidos por las turbinas de las centrales eléctricas con el consiguiente daño para los equipos. Las barreras físicas para impedir estos accidentes son caras y no resultan muy prácticas. Por eso se desarrollan nuevos métodos acústicos que han demostrado una eficacia del 90%. Esta técnica desarrollada por la empresa Fish Guidance Systems (FGS) se basa en una investigación profunda del sistema auditivo de los peces. FGS es el resultado de la colaboración de dos científicos procedentes de campos complementarios, el Dr. Andrew Turnpenny, biólogo marino y el Dr. Jeremy Nedwell, experto en acústica acuática. El Dr. Turnpwnny se dio cuenta de la dificultad de construir barreras físicas para los peces cuando trabajaba en un proyecto para construir una presa en el estuario del Severn. Entonces pensó en espantar a los peces con ultrasonidos.
