Why are freshwater mussels declining?
The mussels have declined by nearly 70 percent because of water pollution and dams, and remaining populations are at high risk of extinction. Freshwater mussels are the most endangered group of organisms in North America because they are highly sensitive to water pollution.
Why are mussels declining?
Factors contributing to the decline of mussels are overharvest, siltation of their habitat, from agriculture, poor land management, channelization, and impoundments, pollution by herbicides, pesticides, and other chemicals ( Mussel Biology WWW).
How do freshwater mussels die?
Dozens of mussel types have already gone extinct in North America, wiped out by water pollution, human development and habitat loss. The current die -off is just one more threat, widespread and fast-moving. And its cause – Richard, the biologist, says that’s the challenge. It could be a million things.

Do zebra mussels die out of water?
Zebra mussels may survive up to two weeks out of water.
What happens when mussels die?
When the mussels die, their decomposing bodies spur a brief pulse of productivity, followed by a steep decline in species diversity as rivers become cloudier and darker without mussels to filter the sediment. It’s a phenomenon Agbalog and Richard have seen along the Clinch.
Are freshwater mussels rare?
Freshwater pearl mussels are incredibly rare and only exist in a few river systems in the UK. Adult mussels have a robust, brown-black shell of elongate elliptical shape with a concave ventral margin.
