Now residents are being urged to report sightings of the creatures.
A spokesperson for the Nene Park Trust, which runs Ferry Meadows, said: “We’ve had a few reports of Chinese Mitten Crab over the past week, particularly around Orton Water.
"Unfortunately there is very little we can do about them as they are naturally spreading through our waterways and water courses. These recent sightings have been reported to the relevant authorities.

A spokesperson for The Marine Biological Association said the crabs can be identified by their white-tipped, furry claws.
They said: “It is important that their spread is monitored and therefore we encourage the public to either submit sightings here to us at DASSH or to record their observations on iNaturalist, an easy to use citizen science platform at https://www.inaturalist.org/”
According to https://www.mittencrabs.org.uk/, Chinese mitten crabs are officially listed as one of the World's 100 worst invasive species. They can cause damage to fishing gear and river banks, block intake screens, modify natural habitats and compete with native species. It is this economic and ecological damage that makes this crab such an unwelcome arrival. The full extent of these exotic pests in English and Welsh waters is currently unclear and a consortium of research institutes is requesting mitten crab sightings from members of the public, anglers and waterway workers, to clarify the distribution of this species.
