Brown trout have had to be rescued from a tarn in the Lake District using unusual fishing equipment
after months of dry weather led to the oxygen supply becoming dangerously low as the water level fell.
Volunteers from the South Lakes Rivers Trust and the Coniston and Crake Partnership have been stunning the trout using electrical signals and then fishing them out so they can be safely moved to a nearby stream, the Westmorland Gazette reports.
Such a move may help preserve the trout so that those bringing their fishing tackle
to the Lake District can still fish in the area.
National Trust ranger Kevin Fairclough told the paper: "By rescuing the fish now we're hoping we can repatriate the fish elsewhere to protect their populations."
Yew Tree Tarn also has the problem of water leakage through the dam built at one end, which the ranger said cannot be fixed because of a faultline running under the tarn.
The tarn was enlarged by the dam in the 1930s by landowner James Marshall, who was also responsible for the creation of Tarn Hows nearby through damming a stream to turn three small tarns into a larger one.
