Abstract

Spring Cavefish (Forbesichthys agassizii) inhabit springs, streams and subterranean aquatic habitats from Missouri to Tennessee. In Illinois, most fisheries survey programs do not sample habitats in which Spring Cavefish can be found, and therefore, its distribution and ecology are poorly understood in the state. We reviewed records of the species within Illinois fisheries databases and museum collections and performed targeted surveys for the species in both 2003 and 2013 to better evaluate distribution status and trends. At a coarse spatial resolution, Spring Cavefish distribution appears stable; however, temporal variability in its presence at individual locations suggests the species may be vulnerable to local extirpation. Evaluation of environmental setting relative to Spring Cavefish distribution suggests water quality may influence presence more than physical characteristics. This study highlights the need for targeted surveys to monitor the status of this species.
