EFKO range of electric fishing devices

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.

Subcategories

  • Portable devices

    The EFKO portable electric fishing equipment is designed to provide an efficient, safe, and mobile solution for capturing fish in both fresh and brackish water. Compact and durable, it is suitable for environmental professionals, researchers, and aquatic ecosystem managers.

    Thanks to its advanced technology, it operates with direct current or a combination of direct/pulsed current, ensuring maximum efficiency while preserving the welfare of the captured species. Compliant with VDE standards and the IEC 60335-2-86 directive, it guarantees safe use.

    Ideal for:

    • Scientific or management fishing

    • Collection of broodstock and juveniles

    • Monitoring and regulation of fish populations

    Easy to transport, with a weight ranging from 11 to 30 kg and a power output between 1000 and 4000 W, these models offer great autonomy in the field.

  • Stationary Device

    The EFKO stationary electric fishing device is designed for fishing operations requiring a fixed installation, such as laboratories, research centers, fish farming stations, or extended field studies. It offers a reliable, powerful, and secure solution for selective fish capture in both fresh and brackish water.

    Equipped with advanced technology, it operates with direct current or a combination of direct/pulsed current, with precise settings to adapt to different species and fishing conditions. Its stationary design provides a constant power supply and maximum efficiency, even in intensive contexts.

    Compliant with VDE safety standards and the international IEC 60335-2-86 directive, this equipment ensures safe usage while respecting the welfare of the targeted species.

    Main applications:

    • Scientific and technical fishing in fixed installations

    • Collection of broodstock for reproduction

    • Ecological studies and fish population monitoring

    Robust and customizable, the EFKO stationary device is an essential tool for professional organizations involved in the management and preservation of aquatic ecosystems.

  • Accessories for...

    Here is a list of accessories for electric fishing, with a brief description of each. These items are commonly used alongside electric fishing devices such as those from the EFKO brand.

    Electric Fishing Accessories – List and Descriptions

    1. Anodes and Cathodes (Electrodes)
    Essential components for creating the electric field in the water. Available in various shapes (ring, comb, sphere) depending on the need.
    Use: Submerged in water to attract fish via electrical stimulation.

    2. Insulated Landing Net
    Specially designed landing net with an insulated handle for safely handling fish.
    Use: Retrieve fish after electric capture without the risk of electrocution.

    3. Insulated High-Voltage Cables
    Durable, waterproof cables connecting the device to the electrodes. Built for tough field conditions.
    Use: Safely transmits electric current.

    4. Remote Safety Switch (Control Handle)
    Allows remote control of the electric current, often through a trigger handle.
    Use: Instantly turn the current on/off to ensure safe operations.

    5. Carrying Backpack or Harness
    Ergonomic system for easily transporting the portable unit in the field.
    Use: Ideal for hard-to-reach areas or river environments.

    6. Reinforced Transport Case
    Shockproof and waterproof case to protect the control unit and accessories.
    Use: Protection during transport or storage.

    7. Water Conductivity Tester
    Measures water conductivity to adjust current settings.
    Use: Ensures optimal efficiency and fishing safety.
