Regulations and controls exist to protect native wildlife species from threats caused by the introduction of non-native species. Non-native animals can carry and spread diseases to which native species often have no defence. They can also out-compete native animals, putting pressure on their populations and often resulting in population decline.

There are legal controls in the UK to protect native crayfish and lobster populations from the damage that can be caused when non-native varieties are introduced into their habitats. These aim to prevent both deliberate and accidental introductions of non-native species by placing conditions on their introduction to the UK and their location once they are in the country.

These conditions are imposed through licensing systems. Those wishing to introduce or keep non-native species must obtain appropriate licences before doing so.

This guide explains the regulations and licensing requirements that apply to non-native crayfish and lobsters. It tells you which activities are controlled or prohibited under the legislation, and the type of licence you need to cover your activities.
