Home \ Animals & Exhibits \ Aquatic Invasive Species
Aquatic invasive species are non-native organisms that harm the environment, economy, or human health. They outcompete native species, take over recreational areas, and can cost millions of dollars to control. Lake Champlain has fifty known invasive species. Some arrived here by natural forces, but most were introduced by people.

The following species are considered high management priorities:
  •    Alewife
  •    Asian Clam
  •    Eurasian Watermilfoil
  •    Japanese Knotweed
  •    Purple Loosestrife
  •    Water Chestnut
  •    Zebra Mussel

What You Can Do
Do not release
When baitfish or unwanted pets are released into the Lake, they can cause unexpected harm. Likely introduced into Vermont waterways by anglers, alewife have hurt fisheries by competing with native fish for food and feeding on their eggs.

  • BUY non-invasive plants and fish for your home aquariums.
  • DISPOSE leftover bait into the garbage.
  • DON’T DUMP unwanted plants or animals into the wild.
Clean, drain, and dry
Most invasive species’ introductions take place by accident when they “hitchhike” on boats. Small invasives, such as the spiny waterflea, can be difficult to detect by eye and survive in very small amounts of water.

Help Prevent the Spread of Aquatic Invasive Species:
  • CLEAN off aquatic plants, animals, and mud from your watercraft and other equipment.
  • DRAIN water from your watercraft including the motor, bilge, live well, and ballast.
  • DRY your watercraft for five days or more when moving between waters in order to kill small species not easily seen.
