Volunteers get their feet wet!
Our volunteers have been getting their feet wet helping The Tees Rivers Trust Fisheries Officer, Richard Holmes, with electrofishing surveys over the summer. This work continues the electrofishing surveys that started in 2014 on a number of local becks that run through the HoT area. A total of seven becks are being monitored again to monitor the fish stocks within them.
The surveys have shown similar numbers and species of fish although there have been a couple of surprises and discoveries. Firstly, a large eel of about 2.5ft turned up in Scur Beck. This was great to see as eels are now an endangered species having suffered an estimated 98% collapse in stocks. It was also surprising to find one so far up the river. Eels start life in the Sargasso sea of the Mexican Coast and move with ocean currents, looking more like a leaf than an eel for the first 2 years. As they reach brackish waters they become tubiform and free swimming. They then move into rivers and wetlands and stay for between 8-15 years before making the journey back to the Sargasso. An eel of the size we caught would have been around 10 years old.
Another pleasant surprise was a new survey section of Deepdale Beck. The beck contained a really healthy population of brown trout up to about 20cm and stoneloach.
