Freshwater mussels are the most threatened taxonomic group in North America with extinction rates that exceed those of many species found in both terrestrial and freshwater ecosystems including fish, birds, and amphibians. Part of the reason that mussels are so threatened is because their larvae are parasitic on fish, making the completion of their life cycle dependent upon healthy fish populations. The imperilment of freshwater mussels is a cause for concern because of the benefits that mussels provide to freshwater ecosystems including habitat enhancement, substratum stabilization, nutrient cycling, and water clarification. Restoration and conservation efforts targeting western freshwater mussels have …
