the question
What design features are incorporated into the Elverator, floating elver trap, and how well does it perform?
the conclusion
Floating design, EF-16 climbing substrate, covered, water delivery to climbing substrate, supplemental attraction flow, and collection vessel location, all contribute to a successful design.
The Elverator outperformed in number of elver collected when compared to a conventional ramp trap in a study on River Lagan, Sweden in 2016 and three conventional pipe traps on River Gota alv, Sweden in 2018. In addition, the Elverator collected a greater range of elver sizes.
