Electric fish barrier

An electric barrier is a device specially designed to control and regulate the passage of fish in waterways and aquatic installations. Primarily used in fishery management and conservation programs, this system allows blocking or channeling fish without causing them harm, thereby facilitating population monitoring or the protection of sensitive habitats.

This device can operate through a combination of techniques, notably the use of adapted electric fields that deter fish from crossing certain areas, while complying with safety and animal welfare standards. The Hans Grassl fish barrier is robust, easy to install, and suitable for both natural and managed environments.

Ideal for ecological studies, monitoring fish migrations, and preventing the spread of invasive species, this system integrates perfectly into sustainable aquatic resource management strategies.
