  EFKO range

  An electric fishing device, also known as an electrofisher or electrofishing unit, is a device primarily used to capture or study freshwater fish in a temporarily non-lethal manner. Below is a general description of how it works and its components:

  1. General Description

  The electric fishing device emits an electric current into the water to trigger a reaction in the fish known as galvanotaxis: the fish are drawn toward the positive electrode (anode), making them easier to catch using a net.

  2. Main Components

  Power Generator

  • Portable device (often worn as a backpack) or stationary.

  • Produces pulsed direct current (DC) or alternating current (AC).

  • Adjustable voltage (typically between 100 and 600 volts).

  3. Anode (Positive Electrode)

  • Often a metal ring attached to the end of a pole.

  • Operated by the user to direct the electric field.

  4. Cathode (Negative Electrode)

  • Immersed in the water (often dragged behind the operator or attached to their belt).

  • Completes the electric circuit.

  5. Power Source

  • Rechargeable battery (commonly lead-acid or lithium).

  • Must provide enough power to generate the electric field in the water.

  6. Usage

  • Scientific studies (fish population surveys, monitoring, etc.).

  • Fisheries management (fish relocation, restocking, etc.).

  • Conservation efforts (relocating endangered species, controlling invasive species).

  7. Safety and Regulations

  • The use of these devices is regulated in many countries (permits, required training, etc.).

  • The current can be dangerous to humans and animals if misused.

  • Should only be operated by trained personnel using proper protective equipment.

  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.
