Did you know that a single freshwater mussel can filter up to 15 gallons of water per day, removing impurities and clarifying the water?
Freshwater mussels are considered keystone species in aquatic communities around the world. They provide ecosystem services, including water filtration and streambed stabilization, which help maintain the health of our streams, rivers, and lakes. Unfortunately, we are at risk of losing this vital resource, as 74% of mussel species in North America are recognized as endangered, threatened, or of special concern.
Jordan Allison, Fisheries Biologist with the Pennsylvania Fish and Boat Commission, will discuss the ongoing species recovery efforts in the West Branch Susquehanna River and freshwater mussel diversity, life history, and ecology.
