The Larinier fish pass, thought to be the largest constructed in England by a Rivers Trust, enables a diverse range of fish species to move upstream to find suitable river habitat for feeding and spawning.
The design and construction of the fish pass was a complex process to ensure the heritage value of the weir and the surrounding area was not adversely affected. Darley Abbey weir forms part of the Derwent Valley Heritage Site with a great many other important historic mills and weirs along the river.
The fish pass was built using an grant provided by Defra under the Catchment Restoration Fund. The work was completed in partnership, with support from the Environment Agency, Derby City Council and Derwent Valley Mills World Heritage Site.
The Trent Rivers Trust has now built a series of fish passes in the Trent catchment, including the Burton Bridge fish pass in Burton-on-Trent and they continue to investigae the scope for opening up other important stretches of river to migratory fish, by building new fish passes or removing redundant weirs.
