What steps should be taken if mussels are found on a watercraft?

The correct action when mussels are found on a watercraft is to document their locations and conduct a full decontamination. This process is essential for preventing the spread of invasive species like zebra or quagga mussels, which can pose significant ecological and economic threats to water bodies.

Documenting the locations of any discovered mussels is important for understanding the extent of an infestation and implementing control measures. A detailed record can aid in management efforts by reporting the incident to local authorities or watercraft inspection programs.

Conducting a full decontamination is critical as it ensures that all mussels, their larvae, and any eggs are completely removed from the watercraft before it is transported to another location. This comprehensive cleaning process typically involves high-pressure washing, draining all water from the boat and equipment, and drying them, as these steps will help eliminate the risk of spreading these invasive species to other water bodies.

The other options do not prioritize the necessary precautions needed to manage and control the spread of invasive mussels effectively. Ignoring the problem or attempting to remove mussels manually without reporting can lead to greater issues for the ecosystem. Seeking assistance from a local marina might provide help, but it does not substitute for proper documentation and decontamination, which are the most
