Marine biosecurity

Last edited: Apr 4, 2022, 3:58 PM

Biosecurity is about taking action in order to minimise the introduction, spread and establishment of invasive non-native species (INNS). Movement of vessels, equipment and/or stock can cause both the introduction of a new INNS and the spread of an INNS already established at a site to new locations.

We all rely on the health of our marine environment to prosper. Once INNS become established they can threaten the diversity of life in our seas and coasts, as well as impacting on our livelihoods and our sport, leisure and enjoyment of the marine environment.

In the marine environment, the complete eradication of INNS is rarely possible or affordable and control is usually only effective on a local scale. Therefore following best practice biosecurity measures to reduce the likelihood of introducing an INNS in the first place are all the more important.

Marine biosecurity planning

Damage to the marine environment can lead to financial losses to marine industries such as additional costs for removing biofouling on structures or damage to farmed shellfish and reduced yield. Effective biosecurity planning can help reduce these impacts. A marine biosecurity plan will outline the realistic actions that can be implemented and achieved to help reduce the risk of marine INNS. Guidance has been produced to take you through how to write a biosecurity plan:

Guidance for recreational activities

Individuals can play a key part in improving biosecurity and protecting the environment when out and about enjoying the water. Whenever you leave the water remember to Check Clean Dry. Download a Check Clean Dry leaflet for:

Pathway Action Plans

Pathway Action Plans have been developed to provide guidance for different organisations and individuals on steps to take to reduce the risk of INNS. The following are relevant to the marine environment:
