A Denver-based federal team fighting invasive freshwater mussels is investigating new and hopeful treatments, including poison, blasts of ultra-violet light and shock waves, and the introduction of a mussel-destroying predatory sunfish.
The researchers testing these tactics say some seem to work and, if proved, could save tens of millions of dollars by protecting western hydropower and water delivery facilities against the proliferating Eurasian quagga and zebra mussels.
“Once the mussels are there, this would help control them,” said U.S. Bureau of Reclamation mussel program coordinator Leonard Willett, who this week was supervising tests at dams along the lower Colorado River.
