Water quality appears to be compromised. If water quality conditions improve in the future, managers will assess the river for potential reintroduction. However, this is unlikely in the near future. | |||||||||||
| Tan Riffleshell Mussel | F | 4 | Asheville Ecological Services Field Office (828) 258-3939 | Tan riffleshell | Epioblasma florentina walkeri (=E. walkeri) | 1 | 1.1.1 | Determine species' current distribution and range | Ongoing Current | Prior to FY 1995 | U.S. Fish and Wildlife Service | U.S. Fish and Wildlife Service, Endangered Species Division, Tennessee Valley Authority , USFWS Regional Office 4 - Atlanta, USFWS Regional Office 5, Virginia Water Control Board, Virginia Commission of Game and Inland Fisheries | Research: Population Surveys, Research: Habitat Status | Graduate Student, Species Expert, Contract, Internal Field Assistance | This subspecies was recently determined to actually represent two taxa. One is now restricted to ~12 miles of Big South Fork, Cumberland River system, TN/KY, while the other is essentially restricted to the upper Clinch River system in 2 miles of Indian Creek, VA. The Big South Fork population appears to at least be stable, while the Indian Creek population continues to decline in status, and the species is becoming increasingly difficult to locate there. However, a few gravid females are obtained during most years for propagation efforts by the State of Virginia. Other populations thought to occur at the time of the 1984 recovery plan, and the subsequently rediscovered Hiwassee River, TN, populations are now considered extirpated. See the final 5-Year Review for details. This information is more/less up-to-date as of August 2014. | |||||||||||

Some propagation technology has been conducted, but growout of juveniles to a size/age where predation is significantly reduced appears to be a recovery constraint. In 2006, 5 gravid females were found and used for streamside infestation of host fishes. Glochidia were pipetted from female brooding gills onto host fish gills. Both female mussels and infected host fishes were immediately released back into their habitat. Subsequent survey efforts have yielded little evidence that these efforts have borne newly recruited mussels to the population. | |||||||||||

Further, riparian habitat restoration work has been and continues to be conducted in the Clinch River system. These projects serve to reduce sedimentation and nutrients to this species' habitat. Outreach efforts to educate the public are being implemented during widely publicized cultured juvenile releases by the State of Virginia in the upper Clinch and to local officials in the Indian Creek watershed. | |||||||||||

The specie's rarity is limiting the number of broodstock available for culture. However, some basic aspects of its biology are now known. Further, streamside infestations on its host darters have been attempted in Indian Creek and adjacent parent stream Clinch River, but apparently were not successful. However, a few gravid females are obtained during most years for propagation efforts by the State of Virginia. Other populations thought to occur at the time of the 1984 recovery plan, and the subsequently rediscovered Hiwassee River, TN, populations are now considered extirpated.

In 2004 and 2005, cultured juveniles of the species were reintroduced into the upper Clinch River in a reach the species was eliminated from following a 1998 chemical spill. Monitoring has not detected the species and this effort appears to have failed. A similar reintroduction of juveniles into the Hiwassee River took place in 2000, but there has been no sign of survival there either. The Indian Creek population has been augmented by lab-cultured juveniles in an effort to improve its population status, which continues to decline. | |||||||||||

Managers have learned over the past several years that release of large numbers of several week only individuals is futile due to the ultra-high levels of predation by a suite of predators. Similarly, streamside infestations for mussels with small host fishes like darters also appears to be futile. Growing out individuals until they reach a tagable size (~10-15 mm long) appears to be the best method for reintroducing Epioblasma spp. See draft 5-Year Review for details. |
