Endohelminth parasites of seven goodein species (Cyprinodontiformes: Goodeidae) from Lake Zacapu , Michoacán, Central Mexico Plateau

A total of 11 parasitic endohelminth taxa were found in 7 freshwater fish species of the subfamily Goodeinae in Zacapu Lake, Michoacan, Mexico. Six were adults (Margotrema cf. bravoae, Phyllodistomum sp., Saccocoelioides sogandaresi, Rhabdochona lichtenfelsi, Bothriocephalus acheilognathi and Caryophillidae gen. sp.), while the remaining 5 taxa (Clinostomum complanatum, Posthodiplostomum minimum, Tylodelphis sp., Eustrongylides sp. and Polymorphus brevis) were larvae. The taxa S. sogandaresi, Tylodelphis sp., and R. lichtenfelsi reached the highest levels of prevalence and mean abundance among all hosts, while the cestodes B. acheilognathi and Caryophillidae gen. sp. showed the lowest values. This study contributes with the inventory of the freshwater fish helminth fauna in Central Mexico Plateau, and particularly with the previous work that has been done with Goodeinae, a subfamily of freshwater fishes endemic to that part of the country
