Parasitic organisms can affect ecosystems by driving population dynamics of the hosts and influencing community interactions. Reproductive efforts of the host species can be affected due to parasite induced alterations. The effects of parasites on the reproduction of their host was investigated by calculating Shannon's diversity, Simpson's diversity, species richness, parasite abundance, and the gonadosomatic index of the host. Parasite communities were investigated of two host species, Cyprinella venusta and Notropis volucellus, which have varying reproductive strategies. Fish were collected from a single site on the Paluxy River, TX from May--September in 2014 and 2015, and returned to the lab to measure parasite abundance, diversity, and host reproductive potential. Our results revealed significant differences in parasite diversity and abundance between the two species, but not between males and females within the species. Interannual parasite diversity and abundance differed significantly in C. venusta but not N. volucellus. Additionally, we recorded a significant, positive correlation between the gonadosomatic index and total number of helminth parasites in C. venusta but not N. volucellus. The results indicate a difference between the two species in terms of parasite diversity and abundance during the breeding season. In conclusion, the mating strategy of the host should be considered when comparing the relationship between parasitic infection and reproduction of the hosts between species.
