WATERLOO (KWWL)-A local nature center is stocking up to help the Cedar River.
The Hartman Reserve and Conservation Agencies are raising mussels in cages at George Wyth State Park.
Largemouth bass and walleye will be infested with larval mussels and the mussels will be allowed to grow during the summer.
Conservation officer Tony Brady says mussels indicate if something is wrong in the river, and they help the local economy.
"Mussels in the bottom of the river are like living substrate, says Brady. "They attract small insects, these insecs attract small fish that eat the small insects. The small fish attract bigger fish that attract fisherman. So they are all connected in the circle of life."
Once they mature, the mussels will be removed from the cages and relocated to the Cedar River this fall.
