The DNR teamed up with partners across Wisconsin to deliver and place more than 1,200 hatchery-raised mussels in several Wisconsin rivers where past water quality problems had taken a toll on mussel populations.

“Propagation and reintroduction are a useful conservation strategy to increase the abundance and distribution of native mussel populations,” said Weinzinger. “We’re thankful for the partnerships that made it possible to augment mussel populations in these streams and provide research going forward to help us shape recovery efforts.”  

Weinzinger said that Genoa National Fish Hatchery raised thousands of fatmuckets (Lampsilis siliquoidea) as part of an experiment to research optimum water quality parameters and feeding rates for best survival.

University of Wisconsin-Stevens Point students worked with the DNR conservation biologists to place over 700 mussels at two streams in Portage County to monitor the growth and survivorship of the animals. Results from this student-led project will help determine the feasibility for future reintroduction efforts.

In southern Wisconsin, DNR partnered with the Upper Sugar River Watershed Association to place an additional 500 fatmuckets into the Sugar River to augment existing populations.
