It's a unique approach to tackling the invasive Asian Carp species, by using an underground speaker system at Lock and Dam 8 in Genoa.
Scientists from the University of Minnesota created a sound that actually makes Asian Carp swim away from wherever that sound is coming from.
"Depending on what frequency range you look at can be upwards of 1,000 times more sensitive than the vast majority of fish in the river," said Dr. Peter Sorensen with the University of Minnesota.
Scientists from the University attached five speakers underwater on the lock to keep them from swimming upstream.The sound will play every time the lock opens and continue to play until it closes. It sounds the loudest in the middle of the lock. Scientists say the native fish won't be affected by the noise.
Asian Carp have been spreading north for the last 40 years, they are detrimental to the ecology of the river and disrupt the native species.
Mark Clements owns a fishing barge on the river near Lock and Dam 8. When he first heard about the speaker system he was worried that the native fish would be affected, just like the Asian Carp, and swim away.
But, Clements said hearing from scientists that the native fish shouldn't have the same reaction, he isn't as worried for now.
"The way they have it set up now it won't affect us. If they decide to mess with the gates and change the flow of the river it could destroy the fishing by the dam, yes it could upset it," said Clements.
Clements said if they were to change the water flow from the dam gates that could completely shut the fishing down. But for now, the experiment will only be by the lock and run concurrent with the shipping season.
The University of Minnesota has funding to keep the underground speaker system in Genoa for two years.
