Helminth parasites on the Anatolian khramulya, Capoeta tinca (Heckel, 1843) from northwestern Türkiye, with new host and geographical records

Abstract

In this study, it was aimed to determine the helminth fauna of Capoeta tinca, a fish species endemic to Turkey, collected from Nilüfer Stream (Bursa) between the 2020 Spring (April) and Winter 2021 (February). 81 Capoeta tinca individuals were caught and examined for ichthyo-helminths. A total of 242 parasites of 4 species were detected in the host fish. Dactylogyrus pulcher (6.1%, 16:5 parasite/fish) and Paradiplozoon homoion (20%, 63:17 parasite/fish) were found on the gills of the host fish. Allocreadium isoporum (33%, 149: 27 parasite/fish) and Rhabdochona fortunatowi (9.8%, 14:8 parasite/fish) were recorded in the intestines of the host fish. Among these parasites, A.isoporum was the most common parasite species (33%). Infection values of the helminth parasite species found were evaluated based on season, sex, and host size, and the results were compared with other studies. P. homoion, A.isoporum, and R. fortunatowi are reported for the first time from this host fish. Additionally, Nilüfer Stream was given as a new locality record for A. isoporum and R. fortunatowi.
