Marine pests

Marine pests are plants and animals that are not native to a particular region.

They can be introduced by human activity. Once here, they can harm our resources, marine industries and the natural environment.

Marine pests can have a serious effect on our way of life. They can:

  • affect human health

  • damage coastal areas and structures
  • restrict access to waterways, ports and marinas
  • spread disease.
