Coming up, using the "voices" of the Round Goby to reduce their numbers in the Great Lakes.
Did you know that fish can hear? It's something Dennis Higgs has known
for a long time. And he's using that knowledge to find a way to reduce the Round Goby population in the Great Lakes. The Round Goby is an invasive species
from Europe that found its way to our waters about 20 years ago.....likely through the ballast water in ships. And since that time, it's population has grown to number in the billions. Dennis Higgs has been trying to come up with a way to trap them. And he's come up with an interesting way to do it.....using fish sounds to attract the Round Goby.
Dennis Higgs is an Associate Professor of Biology at the University of Windsor.
