Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, what assessment he has made of the potential implications for his policies of the spread of mitten crabs to Cambridgeshire.

The Government understands concerns regarding the impact of Chinese mitten crab in Cambridgeshire. However, whilst we continue to take steps to prevent the further spread of Chinese mitten crab, Defra is not currently aware of any cost-effective or proven methods of controlling this species in areas it is currently present, such as Cambridgeshire. Due to the known impact of this species we continue to monitor for any new viable methods of controlling and managing populations and to preventing further spread.

Although control in currently impacted areas is not currently possible, Defra has taken clear steps towards reducing the spread of this species. Chinese mitten crab is listed as a ‘Species of Special Concern’, this means it cannot be brought into GB, kept, bred, transported, sold, used or exchanged, allowed to reproduce, grown or cultivated, or released into the environment.

Defra also funds the Fish Health Inspectorate to carry out work to prevent the illegal sale and spread of this species and continues to support the ‘Check Clean Dry’ campaign which offers aquatic biosecurity advice to minimise the risk of spreading invasive plants and animals to new areas.
