Sorensen, the director of the Aquatic Invasive Species Research Center, holds an underwater speaker. They hope to receive $60,000 in funding to order and install five 196-decibel speakers at the Lock & Dam #8 on the Mississippi River at Genoa, Wis. to stop the spread of bighead and silver carp, which are successfully breeding below the dam.
