Abstract (Summary)

Host-parasite relationships are useful in establishing evolutionary histories and as bioindicators for monitoring environmental change. This study examines infection levels of monogenea gill parasites on Tennessee Snubnose Darters (Etheostoma simoterum). This year-long survey of E. simoterum collected monthly from a tributary of the Paint Rock River determined a parasites-per-host range of zero to seven, with a mean prevalence of 18%, and a mean intensity of 1.9. Correlations were identified between host breeding season and parasite infection levels with host breeding months (spring) having the highest infection rates. E. simoterum length, mass, sex, and condition index were found to not be predictive of monogenea gill parasite infection levels, perhaps due to the low levels of occurrence within the host population. Based on confocal imagery the monogenea parasites collected from E. simoterum are currently of a single unnamed type and thus are tentatively identified as Aethycteron simoterum sp. novum.
