New host and distribution records for three species of (Dactylogyridae: Monogenea) from the endemic Anatolian fish species, Steindachner, 1897 (Teleostei, Leuciscidae) in Turkey: Occurrence in relation to seasons and host factors.

BACKGROUND

This is the first record of dactylogyrid parasites from the endemic fish species, Steindachner, 1897 in Turkey.

AIMS

The purpose of this study was to define the dactylogyrid specimens of from Sarısu stream.

METHODS

A total of 216 individuals of . were collected from Sarısu stream between winter (February) and autumn (September) 2023 with seasonal intervals (one sample per season) and screened for the presence of dactylogyrid parasites infections.

RESULTS

It was determined that 57 were infected by one or more dactylogyrid parasite specimens (overall prevalence 26.3%). A total of 3 species of dactylogyrid parasites were identified on the gills: Wagener, 1909, Linstow, 1878 and was found to be the dominant parasite species in host fish species.

CONCLUSION

To the best of our knowledge, this is the first study in the world on dactylogyrid parasites of . The host fish represents a new host record for each of the collected dactylogyrid parasite specimens. Furthermore, the present study provides the first record of in Turkish freshwater fish.
