A Canal and river trust has made an appeal for volunteers to help remove a large number of terrapins from Ashby Canal to save the natural ecosystem.
The reptiles are 'taking over' the canal and eating the local wildlife, according to the trust.
Officials think the animals were once pets, as they would not breed in cold UK temperatures.
Richard Bennett, senior ecologist for the trust, said: "Terrapins can cause real damage, munching their way through the canal, so it's important we take action.
"We are looking for people with some experience and quick reflexes to help us catch the terrapins and move them to somewhere that keeps them and the wildlife within the canal safe.
"The volunteers will help us to say goodbye to these turtles once and for all on Ashby Canal and protect the native wildlife that makes the canal such a special place for people to visit".
