Washington, D.C. - Congressman Tim Walberg (MI-05) has expressed concern over the recent discovery of silver carp environmental DNA (eDNA) in the St. Joseph River in southwest Michigan. In a letter addressed to Martha Williams, Director of U.S. Fish and Wildlife Service, Walberg called for additional information on this troubling development.

"The presence of silver carp eDNA in the St. Joseph River is a troubling development given the steps Congress has taken to prevent the spread of invasive carp into the Great Lakes and the importance of the St. Joseph River watershed to Michigan’s residents," said Walberg. "This invasive species poses a substantial threat to the native species and the overall health of the Great Lakes region and its economy."

Walberg's letter requests a prompt update on two key aspects:

• Testing Results: Walberg seeks detailed information about the testing data and subsequent reports on the trace of silver carp eDNA within the St. Joseph River. He emphasizes the importance of Congress being provided with updated reporting on the location and timing of the positive test, as well as the ongoing testing being conducted by the U.S. Fish and Wildlife Service (USFWS).
• Current Prevention Efforts: Walberg also calls for an explanation of the current efforts being taken to prevent the invasion of silver carp or other invasive species following the positive test announced on September 7. He specifically seeks insights into the role that USFWS is playing in partnership with the Michigan Department of Natural Resources (MDNR) to address this threat.
