Rhode Island Boater Practice Test

What can you do to prevent the spread of aquatic nuisance species from one waterway to another?

1. Drain the motor, live well, and bilge while close to the shore

2. Allow your boat to dry before its next use

3. Release all live bait into the waterway prior to leaving

4. Run your engine at high RPM to clean props of vegetation

The correct answer is: Allow your boat to dry before its next use

Allowing your boat to dry before its next use is an effective way to prevent the spread of aquatic nuisance species. When a boat is moved from one waterway to another, it may carry small aquatic organisms, including invasive species, in various parts of the vessel such as the hull, motor, or any compartments holding water. By allowing the boat to dry, you reduce the chances of these organisms being transported to a new location, as many aquatic species cannot survive without water for a prolonged period. On the other hand, draining the motor, live well, and bilge while close to the shore does not eliminate the risk, as waterlogged areas or equipment may still harbor species. Releasing live bait into the waterway before leaving can inadvertently introduce non-native species to that waterway, which exacerbates the problem of invasive species. Running your engine at high RPM to clean props of vegetation does not effectively address the problem of carrying aquatic nuisance species since it does not remove organisms that may be clinging elsewhere on the boat, and it can also harm aquatic life. Thus, the best practice is to let your boat dry thoroughly, ensuring that aquatic nuisance species have a diminished chance of surviving and being transported to new environments.
