In the inland waterways, engineering structures often pose obstacles to fish populations, blocking access to spawning and hatching areas, and generally having a detrimental effect on fish habitats. Local councils and water boards support initiatives aimed at preventing waterways from becoming obstacle courses and disrupting fish migrations. 

In partnership with consultancy and engineering firm Tauw, Jansen Venneboer has developed an ingenious and cost-effective way of enabling fish to swim safely through weirs and pumping stations: the Meyberg Fish Passage System.  

This easy-maintenance polyethylene fish passage system contains a number of chambers interconnected by vertical slots. The surface of the chamber floor is rough and, because the water current passes slowly along the passage, the fish can easily find their way upstream.

The Dutch Water Board Rivierenland is measuring the number of fish using the passage system by placing a funnel behind a weir, and counting the fish that enter it. Over a three-week period last year, the fish count totalled 1654.
