Evaluating innovative coatings to suppress priority AIS

This project will develop and test a new coating that can mitigate the spread of zebra mussels while minimizing non-target impacts. The build-up of algae, microorganisms, and bivalves such as zebra mussels onto surfaces is a natural phenomenon known as biofouling. A current way to fight biofouling involves using coatings that contain metals, which are harmful to the environment. This project is evaluating a new generation of coatings containing a non-toxic, anti-fouling biological molecule.

Coated samples will be submerged in the field and samples will be analyzed using microscopy. Organisms present will be quantified and measured. If successful, enzyme-based coatings could help mitigate the spread of invasive species like zebra mussels in Minnesota and beyond.
