What you need to know

To help protect our environment:


Lakes, ponds, rivers, streams.

Impact on environment

Herbivory can negatively impact plant growth, survival and community composition, sometimes leading to aquatic plant collapse in lakes. Selective feeding can promote weed success.

Competes with native fish for invertebrates. May cause lake to flip to turbid state by eating zooplankton and re-suspending sediment.



Check equipment and vessels for freshwater pests, clean everything that has been in contact with the water and dry everything thoroughly.
