Round gobies (Neogobius melanostomus) have made it in to Lake Simcoe in Ontario, Canada, according to this story at myKawartha.com. The news is disappointing to many, especially after workers spent significant money and time last year treating the adjacent Pefferlaw Brook with rotenone (a piscicide) in order to prevent the gobies from making it to the Lake.
Am I misunderstanding something? How does treating a lake with herbicide kill fish, or is it something toxic to animals as well?
Sorry..."herbicide" is just what a tired botanist types when she meant to say "piscicide." Fixed.
