Native freshwater mussels grew more slowly when invasive Asian clams (Corbicula fluminea) were abundant. The study was led by Wendell Haag, a USDA Forest Service research fisheries biologist. It was published in the journal Freshwater Biology. Mussels live out of sight – buried in the river bottom, eating algae and other small particles of organic material. Mussels are filter feeders and key members of aquatic ecosystems. Unfortunately, mussels are disappearing worldwide, and about 70 percent of the 300 mussel species native to the U.S. are in danger of extinction. Addressing mussel declines is difficult because their causes are mostly unknown.

This past August, a new population of golden clams, Corbicula fluminea, was discovered by twelve-year-old budding conservationist, William Guthrie. The new infestation was found in Briggs Lake (Sherburne County). The discovery of golden clams in Briggs Lake is significant because it is an inland lake with no supplemental heat source. If the clams can survive our winter months, they could also spread and reproduce in additional lakes and rivers. Similar to zebra mussels, infestations of golden clams can clog water intake pipes and alter local ecosystems.
