[From Press Release] Great Lakes resource managers can now determine rivers that may be vulnerable to Asian carp spawning if they were to spread into the Great Lakes Basin, according to a new U.S. Geological Survey report.

Findings indicate that two species of Asian carp—silver and bighead carp—may be able to spawn in more Great Lakes tributaries than previously estimated…

Results indicate that Asian carp can successfully spawn in river stretches as short as 16 miles, which is considerably shorter than the 62 miles previously thought to be required. Scientists analyzed water temperature, streamflow and water quality in two Lake Michigan tributaries (the Milwaukee and St. Joseph rivers) and two Lake Erie tributaries (the Maumee and Sandusky rivers). Findings and techniques from this report can be used to identify other rivers vulnerable to Asian carp spawning in the future. ..
