Back in the late 1990’s, South Georgia was experiencing one of the longest droughts in recorded history, many streams became completely dry and several rivers were at lowest levels in years.  The WSNFH was asked to assist in savage operations in the summer of 2000 in Spring Creek, a tributary of the Flint River, there mussels became isolated to specific reaches within the stream.   Approximately 1,375 live mussels were transported to WSNFH to be held in refugia until conditions in the stream improved.  A total of 1050 mussels were returned to their original habitat in Spring Creek on June 5, 2001 (71% survival for 1-year in captivity).  All mussels returned to the creek were tagged for future survival studies. species was formerly abundant,it is possible that this filtration acted to clarify river water to the benefit of other species,including juvenile Atlantic salmon (Salmo salar) and brown or sea trout (Salmo trutta) (Zuiganov et al.1994).

Before the development of plastic, buttons were made from mussel shells. The app is focused on native mussels, so it doesn’t address the issue of invasive species like zebra and quagga mussels, though it does contain some information about the threat that zebra mussels pose to native mussels.  Once the mussels had reached a length of 3-5 millimeters they would be transferred to the newly developed pond culture system that has been installed in one of the mussel ponds here at the facilities.
