|Freshwater Mussels of the Upper Mississippi River System|
Mussel Conservation Activities
Work continues to identify host fish and propagation techniques for a variety of Upper Mississippi River mussels. Some species like black sandshell (Ligumia recta), mucket (Actinonaias ligamentina), fat mucket (Lampsilis siliquoidea) and plain pocketbook (Lampsilis cardium) have been successfully propagated. Identifying a host fish for spectaclecase (Cumberlandia monodonata), a federal candidate species, still eludes researchers.
Juvenile black sandshell (Ligumia recta) collected in August, 2006, from a closed propagation cage in the Upper Mississippi River, Pool 4 (Frontenac), Minnesota. Juveniles are three years old. Photos by Gary Wege, U.S. Fish and Wildlife Service.
