Question: 1 / 400

What is a common method of AIS decontamination for infested watercraft?

Use of oil-based cleaners

Flushing with hot water

Flushing with hot water is a widely recognized and effective method for decontaminating infested watercraft from aquatic invasive species (AIS). This method works by utilizing high temperatures to kill invasive organisms that may be residing on or within the watercraft. The heat disrupts the biological processes of these organisms, making it less likely for them to survive and spread to new water bodies.

This approach is particularly advantageous as it avoids the use of chemicals, which could have harmful effects on the aquatic environment if not managed correctly. By focusing on thermal decontamination, watercraft owners can effectively remove invasive species and prevent their introduction into non-infested waters.

In contrast, oil-based cleaners may not effectively target all AIS and could potentially cause environmental harm. Sanitizing with chlorine, while effective against some pathogens, might not be suitable or environmentally friendly for all situations involving AIS. Scraping off invasive species by hand can be inconsistent and may leave behind viable organisms that can regrow or reproduce. Thus, flushing with hot water remains the preferred method for thorough and environmentally safe decontamination of watercraft.
