GENOA, Wis. — An experimental sound system designed to deter invasive carp has been operating near the Mississippi River shipping lock.
The St. Paul Pioneer Press reports (http://bit.ly/1miO05k ) that University of Minnesota scientists demonstrated their project Monday in Genoa. It features five underwater speakers that produce a sound the carp hate.
The $75,000 sound system is designed to prevent the carp from swimming upstream. It's activated every time the downstream gates of Lock and Dam No. 8 open.
The project was funded by state lottery funds and nearly $7,000 in private donations.
The invasive fish, commonly known as Asian carp, are thought to be a major threat to native aquatic species throughout the Midwest.
