Abstract

The parasite fauna of chub Squalius cephalus from the Kaytazdere-Yalakdere stream systems, Sea of Marmara basin, Turkiye, was investigated. Totally, four digenean species (Clinostomum complanatum, Tylo-delphys clavata, Posthodiplostomum sp. and Ichthyocotylurus sp.), one nematode species (Rhabdochona denudata), one monogenean species (Dactylogyrus nanus) and two myxosporean species (Myxobolus sp. 1 and Myxobolus sp. 2) were identified. Overall infection prevalence, mean intensity and mean abundance were 87.0%, 22.1 +/- 2.5, 16.2 +/- 2.0, respectively. Myxobolus sp. 2 was the most prevalent parasite species, followed by Myxobolus sp. 1 and C. complanatum. Dactylogyrus nanus was the most abundant parasite species, followed by C. complanatum and Ichthyocotylurus sp. The species Thylodelphys clavata, Postho-diplostomum sp., Ichthyocotylurus sp., Myxobolus sp. 1 and Myxobolus sp. 2 are new parasite records for S. cephalus as well as new geographical records in Turkiye.
