Thread herrings (Opisthonema spp.) are economically important fish species in the Tropical Eastern Pacific. Knowledge of parasitofauna commercially exploited is useful as it can increase our understanding biology and ecology. However, knowledge parasites Opisthonema spp. limited. During a fisheries exploration survey April 2022, samples bulleri O. libertate were collected from three oceanograph...

Three species of Pseudodactylogyrus Gusev, 1965 (Monogenea: Pseudodactylogyridae) were collected from the gills of Anguilla reinhardtii Steindachner and A. australis Richardson from several localities in Australia and eels imported to Japan from Australia. Pseudodactylogyrus gusevi sp. n. from A. reinhardtii (type host) and A. australis in Queensland, Australia is most similar to P. bini (Kikuc...

The phylogeny of monogeneans of the genus Thaparocleidus that parasitize the gills of Pangasiidae in Borneo and Sumatra was inferred from molecular data to investigate parasite speciation. The phylogeny of the Pangasiidae was also reconstructed in order to investigate host-parasite coevolutionary history. The monophyly of Thaparocleidus parasitizing Pangasiidae was confirmed. Low intraspecies m...

There is an extensive lack of information on the parasitic fauna accompanying cartilaginous fish in Peru. The objective this work was to identify community parasite metazoans cockfish Callorhinchus callorynchus (Linnaeus, 1758) (Chimaeriformes: Callorhinchidae) from artisanal fishing San Andrés, Pisco, Ica, Thirty-one specimens C. were collected between June 2018 and October 2019. Following nec...
