An operation to remove non-native fish species from a Lancashire reservoir aims to return the reservoir to its natural state.
Rossendale Council has worked with the Environment Agency to arrange the removal of the fish from Wallbank Lodge Reservoir, reports the Lancashire Telegraph.
A spokesman said: “As a result of the fish being placed there unlawfully, the reservoir is now over-stocked and the new species are causing an environmental concern.
“A licensed fishery will carry out the work over the course of a day, netting and electrofishing the animals before relocating them to a more suitable environment.”
Two black swans have also been unlawfully introduced at the reservoir and the Council is taking advice to find a rescue centre that will safely remove them.
