A total of 15 metazoan parasite species belonging to Digenea (6), Cestoda (3), Acanthocephala (1), Nematoda (4) and Isopoda (1) taxonomic groups were identifi ed. Solea solea was found to be infected by Condylocotyla pilodora, Proctoeces maculatus, Opecoelidae gen. sp., Metadena sp., Stephanostomum sp., Progrillotia sp., Capillaria gracilis, Cucullanus campanae, Solearhynchus rhytidotes and Nerocila orbignyi. Arnoglossus laterna was found to be infected by Lecithochirium musculus and Grillotia erinaceus. Scolex pleuronectis, Hysterothylacium aduncum and Dichelyne minutus were determined in both fl atfi sh. Infection prevalence and mean intensity values were re corded for each parasite species. Infection values for each parasite species in relation to season and fi sh size were also determined and compared as comparatively. This study is the fi rst one assessing the metazoan parasites both of S. solea and A. laterna collected from the Turkish coast of Black Sea. While Condylocotyle pilodora and Capillaria gracilis are new parasite records for S. solea, Grillotia erinecaus is new parasite record for A. laterna. Moreover, this paper is the fi rst report on occurrence of Opecoelidae gen. sp., Metadena and Stephanostomum genera in S. solea.

Parasitological investigations were conducted simultaneously at both localities during September 2014, February and April 2015. While a total of 100 fish specimens were examined from Yakakent samples whose average length was 19.37 cm, a total of 88 fish specimens were examined from Milas samples whose length was 22.67 cm in average. Only one monogenean species Diplectanum aequans was recovered from investigated fish specimens at both sampling localities. Infestation prevalence (%) and mean intensity values of D. aequans were 89.0% and 9.6 ± 0.8 in Yakakent samples while those infestation indices were 90.9% and 13.3 ± 1.2 in Milas samples, respectively. The difference between the infestation prevalence (%) values of D. aequans at both sampling localities was not st...

Standard parasitological investigation methods were applied and morphological diagnostic features of the whole parasite, bothria, scolex, tentacular armatures and tentacles were studied in detail using a light and Scanning Electron Microscope (SEM). The plerocercoids of this parasite had a total length of 5.96 mm on average and this was 21.6 mm on average in adults. The measurement data of all morphological diagnostics are provided and photomicrographs of each part of the parasite are presented.

Fish were collected throughout a period from May 2011 to March 2014 from local fishermen. A total of 690 fish specimens near Sinop and 423 fish near Balaklava Bay were examined for parasites. Hysterothylacium aduncum was the only nematode species identified in the digestive tract of the Black Sea whiting Merlangius merlangus. Prevalence of infection, mean intensity and mean abundance values were determined according to season, length classes and sex of fish at both localities. These infection indices were always higher in Sinop samples than those of Balaklava Bay samples.

A total of 906 fish specimens belonging to 6 fish species (Aphanius danfordii, Neogobius melanostamus, Proterorhinus marmoratus, Gasterosteus aculeatus, Platichthys flesus and Chelon auratus) were examined monthly during a period of one year. Four digenean species recorded as encysted metacercariae were identified; these were three species belonging to Heterophyidae, i.e. Ascocotyle coleostoma, Pygidiopsis genata and Cryptocotyle concava, and one species of the family Diplostomatidae, i.e. Posthodiplostomum sp. Ascocotyle coleostoma was found to be the dominant species and detected in all examined fish species. Posthodiplostomum sp. was detected only in A. danfordii. Cryptocotyle concava was detected in N. melanostamus and P. marmoratus. Infection prevalence and intensity were calculated and discussed for each digenean species recorded as metacercariae in relation to season. The eye, heart and gill tissues of infected fish with parasites were examined histologically. The histological evaluation indicated that the histological lesions were more severe in gills.

The sensory quality of its meat mean that it is one of the most highly valued freshwater fish species on the European market. Despite its highly valued meat, studies on its parasite fauna are limited. Here in the present study, metazoan parasites of the pike-perch, collected from Lower Kızılırmak Delta in Turkey were investigated. A total of four metazoan parasites including Ancyrocephalus paradoxus Creplin 1839, Tylodelphys clavata Nordmann, 1832, Bothriocephalus acheilognathi Yamaguti, 1934, Camallanus truncatus (Rudolphi, 1812) were identified. Photomicrographs were presented for each parasite species. This paper is the first report on the parasites of Stizostedion lucioperca in Turkey. Ancyrocephalus paradoxus is a new record for the parasite fauna in Turkey
