European juvenile eel (elver), Anguilla anguilla

How do three different elver climbing substrates compare?

the conclusion

The stubbed substratum, EF-16 climbing substrate, demonstrated “superior performance” in attracting more elver approaches, initiating more climbs and the elver traveled measurably faster up the studded substratum in contrast to either the bristle or open weave substratum. “To recover endangered migrating species, enhancing the performance of passage solutions at barriers between habitats is a critical factor.”
