Suboptimal use fish pass by fish

Print Email


Insufficient fish migration

The free migration of fish is obstructed.

Because of limitations of the designs, current fish passes are not used optimally by fish.


The Fishionpassage

The design of the Fishionpassage is based on model research on flow and fish behavior, which made the ideal configuration for a fish pass possible. The Fishionpassage is shaped organically and is printed out of recycled plastics, which can be reclaimed and reinserted into the production process.
