Aquatic Nuisance Species

An increasing number of damaging aquatic species are invading the waters of Connecticut. Zebra mussels and Eurasian water milfoil are most familiar to anglers but other exotic species may cause problems as well. You can help prevent the spread of problem species by following these simple suggestions!
Before Leaving A Boat Launch:

  1. Completely drain all water from the boat, including bilge water, livewells and engine cooling systems.
  2. Inspect your boat, trailer, and equipment. Remove and discard all aquatic plants and animals you may have picked up while on the water.
At Home:
  1. Rinse boat, trailer and equipment with tap water. A bleach solution can be used to clean livewells. Dispose of all rinse material properly!
  1. Don't dump your bait bucket or release live bait! Avoid introducing unwanted plants and animals. Unless your bait was obtained on site, dispose of it in a suitable trash container.
  2. Do not transport fish, other animals or plants between water bodies. Release caught fish, other animals and plants only into the waters from which they came from.
