Aliens in the app – Our invasive species series

We are releasing an 'invasive species' series, so you can help to identify species in your river that shouldn't be there!

The update contains detailed images on two non-native shrimp – the demon shrimp and the killer shrimp. These shrimps are very bad news for our native shrimp (Gammarus pulex).

Let us know any sightings of these aliens and report them to your local Environment Agency as a matter of urgency.

For all water users, by simply following the Check Clean Dry process, you can do your bit to stop the spread of invasive species.
