Summary
The spread of invasive mussels (Dreissena spp.) has increased water clarity in many Midwest lakes, as the mussels filter algae out of the water. Fish are at greater risk of damage from UV radiation in clearer water, and will move deeper, hide under structure, and take refuge under ice to avoid harm. However, warming temperatures from climate change are reducing ice cover on many lakes, threatening early life stages of species like Cisco with increased exposure to UV radiation.
