Now the spotlight is on two of our most fascinating – and threatened – underwater inhabitants: Freshwater pearl mussel and Thick shelled river mussel. Listen to the podcast as the experts talk about the unknown lives of these species, their dependence on fish, and how restoration is giving them a chance to come back.

Freshwater pearl mussel and Thick shelled river mussel are two of the priority species under Improve Aquatic LIFE. Both mussel species are important for Swedish rivers and environments, but have been severely affected by human activities.

Filtering and improving water
Thanks to research, we are learning more about mussels and restoration efforts and improvements to mussel habitats are helping them re-establish themselves. Mussels are sensitive to pollution and act as indicators of water health.
The life of large freshwater mussels is exciting and fascinating. For example, did you know that a Freshwater pearl mussel can live to be over 200 years old and that it spreads using salmon and sea trout as host fish? And when freshwater mussels filter water, they act as nature’s own purification plant.
