We don't have oysters but we have freshwater mussels in the #AnacostiaRiver. As filter feeders they are our greatest allies in our mission to clean and restore the river. Check out these before and after photos. These small tanks were filled with water and substrate from the same site at Buzzard Point. The tank on the left has 5 adult mussels from the same site (including 3 Eastern elliptios, 1 Eastern pondmussels an 1 Eastern lampmussel). The tank on the right doesn’t have any mussels. See the difference in water clarity after one hour (photo below)! #freshwatermussels#cleanwater#DCwildlife#thisisDC

Home to 41 species of mussels (18 of which are endangered), over 100 species of fish, and a variety of other freshwater species, the Clinch river is among the most biodiverse rivers in North America. Unfortunately, much of this diversity is now under threat. From coal power plants to everyday trash, the health of the Clinch is severely impacted from a number of pollutants.
What many don't realize is that protecting species, like mussels, can have a large impact on water quality and the health of a river. Freshwater mussels act like small water filters, sifting out organic matter and debris resulting in cleaner water. Protecting mussels means protecting rivers!
Freshwater mussels also have some pretty interesting behaviors. Here a female Oyster mussel (Epioblasma capsaeformis) has trapped a fish host using a modified lure. After trapping the fish, the female places her young mussels (glochidia) onto the gills of the fish to help distribute her young. #everydayextinction#biodiversity#extinction#endangeredspecies#freshwater#cleanwater#pickupyourtrash#conservation#freshwatermussels
