Fish Pesticide May Control Unwanted Round Goby (Sep 2, 2008)
U.S. Department of the Interior.
Scientists have discovered that certain chemicals may be useful in slowing the spread of the round goby, an invasive fish species that is threatening parts of the Great Lakes and Mississippi River.
When released near the bottom of a river or lake, two fish pesticides are effective in controlling this bottom-dwelling invader, particularly where dissolved oxygen is low, while leaving native species unharmed.
