The Apalachicola-Chattahoochee-Flint River Basin (ACF) supports one of the most diverse freshwater mollusk assemblages in the Southeast United States.  Historically, the ACF had at least 14 genera and 33 species with six species being unique to the basin.  Over the past decade, numerous surveys were conducted in the ACF and concluded that only 29 native mussels currently exist within the ACF. Details: Freshwater mussels are among North America’s most imperiled species. After European settlement, mussels were harvested for their shells to make pearl buttons. Some of those species extend into Canada and Mexico, but the guide doesn’t cover species exclusive to those countries. “People don’t really realize how many mussel species we have,” Oetker said.  We are currently working with common, un-listed mussel species so that we can refine our methods and incorporate them into protocol and add them to the Warm Springs NFH Mussel Propagation Management Plan for the ACF Basin. Species richness of freshwater mussels in the west and northwest is generally low (Figure 2-2-i, Table 2-2-i), but five of the six species of freshwater mussels in British Columbia are found nowhere else in Canada. They have a fascinating life cycle; their larvae attach to the gills of salmonid fish … The majority of the species we love have been getting less and less common, but there's still time to bring them back.

Freshwater mussels are the most imperiled group of animals in North America, with 66% of species at risk. Wilder Future. Several described methods include producing glochidia in bundles that resemble food items (conglutinates), producing superconglutinates of glochidia that are attached to the mussel by a long mucus string to mimic prey fish, discharging glochidia in a mucus web, modification of mantle flaps in the females to mimic small fish, and releasing glochidia into the water column.  After one week in the system the juveniles doubled in size, suggesting that our nutritional plan is working adequately. The freshwater pearl mussel and its habitat are fully protected by law, under Schedule 5 of the Wildlife and Countryside Act 1981 (as amended) and Annex 2 of the Habitats Directive.

Friends of the Warm Springs National Fish Hatchery.  The system is based on a design by Dr. Chris Barnhart of Missouri State University. He added that local communities know where mussels can be found and how they are used, so their role is crucial to identify and protect freshwater ecosystems, including these new species. The eDNA shedding and decay rates reported within … “Freshwater mussels are among the most endangered species in the world. WSNFH held back several species (approximately 25 mussels), as of January 2008, 12 were is alive and doing well (48% survival after 7 years in refugia).  While the mussels were held at WSNFH, propagation techniques were developed, glochidia were collected from several species and transformed juveniles were collected and kept alive for six months and studied. Here in Vermont there are eighteen separate species of freshwater mussels …  The ACF River Basin drains approximately 51,282 km2 in western Georgia, eastern Alabama, and the Florida panhandle.
