Cumberlandian Mollusk Conservation Program. Activity 8: analysis of macrofauna factors. [Conradilla caelata; quadrula intermedia]
This study provides information that may be critical to the continued survival of the mussels Conradilla caelata and Qadrula intermedia in several rivers throughout the region. The biotic components of several river reaches that have populations of these endangered species were examined to determine what biotic attributes were different from those study reaches that did not have these mussels. In all cases the quantity and quality of the benthos would be considered adequate to sustain those consumers, in this case fish, that are necessary to assure continuation of the mussel community. If fish other than Etheostoma zonale (banded darter) are determined to be acceptable hosts for either Conradilla caelata or Qadrula intermedia then there will probably be adequate numbers at each potential transplant site to accomplish reproduction. During this study we have determined that the benthic macrofauna at all sites is adequate, and supports a fish assemblage of considerable diversity and abundance, hence it is probable that adequate fish hosts are available to accommodate a complex mussel fauna.
