We are the license holder for the Enature® Fishpass in Switzerland and Bavaria.

The system is a further development of the Vertical Slot Pass. It can be used with different types of waterways (with different water channels). It is a multi-structure slot (multiple slot) with an alternation of the slot side. The Enature® Fishpass enables:

• Flow rate reduction up to –25%
• Reduction of water flow up to –40%
• Defined hydraulic conditions
• Standardized precast system
• Short construction time
• Little need for space

Innovations of the Enature® Fishpass system:

• Formation of increased roughness
• Reduced flow velocities in the slot and basin, turbulence and energy dissipation
• Improved fish pass for weak swimming species and juveniles
• Flow minimization vs. economic advantage
