How can boaters prevent the spread of aquatic invasive species?

Cleaning, draining, and drying boats and equipment after each use is the most effective method for preventing the spread of aquatic invasive species. This practice helps eliminate any plants, animals, or microorganisms that may have attached themselves to the boat or equipment during use, reducing the risk of transferring these invasive species to new bodies of water.

For instance, cleaning the hull and any equipment that came in contact with the water ensures that any small fragments or seeds are removed. Draining all water from live wells, bilges, and transom areas prevents any organisms that may be living in the water from being introduced to a different environment. Drying thoroughly before the next use is essential because many invasive species cannot survive without water for extended periods. Adopting this procedure is critical for maintaining healthy ecosystems and protecting native species.

The other options might seem viable but do not effectively prevent the spread of invasive species in the same comprehensive manner. Chemical treatments could contaminate waterways and might not eliminate all species. Simply avoiding certain waterways does not address the problem and may lead to the spread of invasives in unexpected ways. Lastly, purchasing only native species does not prevent the risk of introducing existing invasive species that could hitch a ride on boats or equipment used in multiple areas.
