Officials say a disease might be killing an invasive species of fish in Lake
Ontario and the St. Lawrence River. The GLRC’s David Sommerstein
reports.
Where the lake and the river meet, people have been finding dead round
gobies.
“Dozens in some cases, hundreds of dead gobies that have been washing up on shores.”
Steve Litwiler is with New York’s Department of Environmental
Conservation. He says a change in water temperature or a poison could
cause the die-off, but initial sampling suggests some kind of disease.
“Is it a disease that could potentially affect other fish? Fortunately right
now the only fish that are dying appear to be the round gobies.”
If only the round gobies die, this could be a good news story. Round gobies
hitched a ride from Europe in the ballast of foreign freighters. They’ve
displaced native species across the Great Lakes by breeding faster and eating
other fishes’ eggs and young.
For the GLRC, I’m David Sommerstein.
