“…The increase in temperature due to climatic changes influences the life cycle of C. complanatum from the evaporation of water that results puddles of cold mud and a reduction in the volume of water in the aquatic environment. These phenomena make the habitat favourable for intermediate host snails and increase the chances of the parasite infecting fish (Rizvi et al 2020). In our study, ponds that presented higher temperatures (I15 and I16) had fish with a higher parasitic load of Clinostomum sp.…”

“…Trematode parasites of the genus Clinostomum (Leidy 1856) are widespread and are described considering different approaches such as ecological, epidemiological, evolutionary, genetic, molecular, morphological, taxonomic, and others (Bonett et al 2011, Caffara et al 2014, 2017, Calhoun et al 2019, Chai & Jung 2019, Nicola et al 2020, Rizvi et al 2020. Even so, the dynamic of their host-parasite relationship is not totally revealed (Calhoun et al 2019).…”

This study analyzed the parasitism by Clinostomum sp. metacercariae of the neotropical fi sh Cichlasoma paranaense (Kullander 1983) and environmental variables' infl uence on their host-parasite relationship in Central Brazil. Fish were collected in fi ve impoundments (I) from three towns: Itauçú (n = 2), Inhumas (n = 1), and Goiânia (n = 2), Goiás State, Brazil. Ninety-fi ve fi sh were analyzed, weighted and length measured.Afterward, the presence of metacercariae in the gills, muscles, fi ns, and body cavities was investigated. The metacercariae were fi xed in AFA solution, kept in 70% alcohol, and stained with carmine. The infection prevalence revealed that 0.64, 0.56 and 0.91% of fi sh was infected. The abundance was 4.14, 3.22 and 5.88, with a mean intensity of 6.44, 5.80 and 6.42 per impoundment (I 13, I 15 and I 16), respectively. The frequency of metacercariae was higher in fi sh collected in Goiânia. High frequency of parasites was observed in the gills, muscles, and fi ns. The limnological variables did not present direct interference in the parasitism. The fi sh' standard length infl uenced the number of metacercariae positively but did not differ to the relative condition coeffi cient.
