Upper Dee Riparian Scheme: 2019 Electrofishing Results​​

November 08, 2019

The report provides a brief look at juvenile salmon densities in the upper Dee based on 2019 electrofishing surveys. Full results and stock assessment from all electrofishing surveys in 2019 will be available in early 2020.

Sites in the upper Dee tributaries have been electrofished since 2013. Data gathered during the annual surveys are essential for monitoring juvenile fish populations and distribution in the upper reaches. The UDRS was developed to help offset the effects of climate change and to help establish shade and shelter for juvenile salmon. The study also monitors water temperatures, which remain a long term threat to salmon. The summer of 2018 was a particular concern as water temperatures on certain upland tributaries approached dangerous levels.
