Understanding Mussel-rope Part 1
Many culverts are barriers to fish due to being perched/overhanging or having fast laminar flow.
In the video below, Tim demonstrates how mussel-rope can improve fish passage at perched/overhanging structures.
The rope simulates natural tree roots and fibres that some species have evolved to utilise when migrating upstream.
The type of rope being used here is “looped mussel-rope”.
Looped rope is proving to be an effective remediation tool at perched/overhung structures. It also has the benefit of not shedding fibres as readily as other types of ropes.
