Higgin's eye pearlymussel

Endangered Species Bulletin, Jan-Feb, 2004

As a result of a 2000 Biological Opinion that determined jeopardy for the Higgin's eye pearlymussel from operation and maintenance of the Army Corps of Engineer's Upper Mississippi River Nine-foot Channel Project, we are working with the Corps' on the Interagency Mussel Coordination Team to carry out conservation measures identified in the Biological Opinion. Those measures include genetic studies, mussel culture at the Genoa National Fish Hatchery, culture in cages in the Upper Mississippi River and tributaries, stocking juvenile mussels, relocating adults, stocking fish inoculated with glochidia (parasitic mussel larvae), cleaning and stockpiling adult mussels, and survey/monitoring activities. Those activities are presented in the report "Saving the Higgins' Eye Pearlymussel (Lampsilis higginsii) from Extinction: 2002 Status Report on the Accomplishments of the Mussel Coordination Team," found on the web at http://www.umesc.usgs.gov/mussels/documents/ mct_2002_status_report.pdf

Recovery plans for the following listed species in Region 3 were completed and made public in September 2003:
