Salmon Recolonising the Avon Water, South Lanarkshire
Salmon Recolonising the Avon Water, South Lanarkshire
The Clyde River Foundation’s programme of electrofishing surveys in 2019 included a targeted survey for salmon in the Avon Water, following the full restoration of the fish pass at Millheugh Weir, Larkhall. Two year classes of juvenile salmon were caught above Millheugh Weir but not above Craig Mill Dam, which we now consider a barrier to further upstream spread of the species and which now requires reappraisal in order to realise the full benefits of the installation of fish passes downstream at Ferniegair and Millheugh. Some 14km of new habitat have been recolonised by salmon, and this is an increase of around 5% of the total river length occupied by salmon in the River Clyde catchment. The results and our interpretation of them can be found here:
