Abstract
Cambarus sphenoides (Triangleclaw Crayfish) is endemic to the Cumberland Plateau of Kentucky and Tennessee. There is a paucity of ecological and life history information about this crayfish species. The lack of basic biological information guides the need for an effective and efficient sampling gear for Triangleclaw Crayfish. In this study, we compared kick seining and electrofishing methods in four 100-m reaches in four streams on the Domain: Abbo’s Alley, Barnes Branch, Depot Creek, and an unnamed tributary of Mud Creek. We observed higher catch rates from the backpack electrofishing unit. Sampling for crayfishes with a backpack electrofishing unit is the best method, based on our results, for rocky, shallow headwater streams on the Cumberland Plateau ecoregion.
