I recently introduced a bipartisan bill with Congressman Mark Pocan (D-Madison), that will help keep Wisconsin’s lakes healthy by restricting the access of invasive species of fish.
Fishways serve an important purpose of preserving and enhancing the populations of desirable, native fish by allowing them a way to travel around dams. However, invasive species use these same fishways to invade rivers and lakes and devastate native species and their habitats.
The state of Wisconsin is currently experiencing this problem. The U.S. Fish and Wildlife Service has ordered the installation of a fishway at the Prairie du Sac dam. Asian Carp, which is an invasive species that can grow nearly three feet in length, have been found at the base of this dam. Installing a fishway in this location would allow the Asian Carp to migrate upstream to the Wisconsin River, Lake Wisconsin and eventually the Great Lakes. This would wreak havoc on the natural environment and threaten the Great Lakes $7 billion fishing industry.
My bill will require the U.S. Fish and Wildlife Service to consider the threats posed by invasive species before mandating a new fishway be built. I believe that we have to do a better job of making smart decisions to conserve and protect our environment, and this bill is a great step in the right direction.
