Aquatic invasive species are non-native species that spread rapidly and cause harmful ecological or economical impacts. They are easily transferred between bodies of water; one way that aquatic invasive species are spread is by attaching themselves to watercrafts, and diving and fishing gear. Once attached they can be transported between bodies of water, spreading into native ecosystems and causing environmental and economic damage.

How can you help?

After leaving the water you can remember three simple steps;

(1) Clean any visible debris and plants off your boat and gear;

(2) Drain any water from your boat; and

(3) Dry your boat and gear before leaving the area that you launched your boat in.


Other ways to help:

  • Educate yourself on the threats that aquatic invasive species pose on our native aquatic ecosystems in Nova Scotia
  • Learn how to identify invasive species
  • Remember that you should never release a plant or animal into a new body of water, and only release fish back into the water in which they were caught
  • If you see an invasive species make sure you report it to NSISC or iNaturalist.
  • Help to spread awareness about aquatic invasive species
  • Become a Citizen Scientist
