Check, clean, dry to stop the alien invaders

The killer shrimp (Dikerogammarus villosus)
By Andrea Kelly, Senior Ecologist

Check, clean, dry is the message as the Broads Authority continues to raise awareness of alien invaders.

The Authority is involved in mapping the distribution of the killer shrimp (Dikerogammarus villosus) and the zebra mussel as well as other non-native species.

The highest densities of killer shrimp and zebra mussels are on the eastern shore of Barton Broad and zebra mussels can also be found throughout the Bure, Ant, Thurne and Yare.

It is likely that the water intake from Belaugh to the Trinity Broads will also spread the shrimp.

It is critical to avoid the spread to other waterways by taking the simple steps of check, clean, dry – checking your boat and equipment for invaders before leaving a waterway, cleaning everything and making sure it is all dry. A leaflet is available with further information.

For more details on how we have raised awareness of non-native species please see the Broads Authority website.

Any sightings of non-native species can be emailed to
