Why are mussels considered a significant concern?

Mussels are considered a significant concern primarily because they reproduce quickly and have the capability to clog infrastructure. Invasive species, such as zebra and quagga mussels, can multiply rapidly, leading to dense populations that disrupt aquatic ecosystems and infrastructure. Their tendency to attach to surfaces enables them to clog water intake pipes, facilitate the growth of problematic biofilms, and block the flow in water systems, which can lead to costly repairs and maintenance for municipalities and industries that rely on freshwater resources.

Additionally, these mussels can outcompete native species for food and habitat, further destabilizing local ecosystems. Their presence can lead to declines in native fish populations and other aquatic life, creating a cascade of ecological effects. The overall economic impact and ecological damage associated with mussels highlight why they are treated with such urgency in terms of management and prevention in aquatic environments.
