Our design is based on eel behavior, and perfected in Sweden. The Elverator not only protects elver from predators, independent studies have confirmed this unique floating system safely collects up to 300% more elver, including larger elver, than other existing systems.
The Whooshh Innovations EF-16 Climbing Substrate is a durable and modular substrate that is designed to attract and pass a broad cross-section of eels, from elver to yearlings, with a wide range of sizes.
Original tiles are used throughout the entire ramp except for the uppermost part of the ramp were the end tile is used together with a PVC half pipe (3-4´´ diameter) to create a curved descent to the collecting box (sold separately.)
The EF-16™ tiles comes with a standard width of 200 mm, a common ramp width of 400 mm needs four EF-16™ tiles per meter of ramp.
*Specialized tile sizes can be produced
Typical rivet placement, maximum rivet/screw head size: 6.5 mm, five rivets/screws per tile
