So just how do we combat this problem?
The answer lies within the materials themselves. It is found that marine organisms can attach to some metals and alloys more easily than others. Steel, Aluminum and Titanium are subjective to easy fouling but Copper-based alloys are not!
Copper has been used for many years to protect boat hulls from this very same problem. When copper corrodes, a layer of cuprous oxide is formed. This layer, while relatively harmless to humans, is toxic to the mussels.
