Stationnary electric fishing devices – HANS GRASSL with engine

Stationary Electric Fishing Device by Hans Grassl with Combustion Engine

Hans Grassl stationary electric fishing devices equipped with combustion engines are designed for fixed and intensive electrofishing operations in natural or managed aquatic environments. Permanently installed on the edge of a water body, a bank, or a floating platform, these systems allow for continuous and efficient use without relying on a fixed power grid.

The combustion engine (gasoline-powered) drives a generator that produces pulsed or continuous electric current, compliant with VDE standards and IEC 60335-2-86 directive. This current is transmitted into the water via an anode and cathode, triggering electrotaxis in fish, drawing them toward the anode for easy capture.

Designed for use in freshwater and brackish environments, these devices are ideal for:

• long-term scientific studies,

• fishery monitoring stations,

• conservation projects,

• ecological assessments,

• restocking or population control operations.

Their autonomy, power, and durability make them reliable tools for fishery professionals and researchers. The system includes safety features such as an emergency stop switch and precise current adjustment settings.
