Two endemic freshwater cyprinid fishes, Capoeta caelestis Schoter, Ozulug & Freyhof, 2009 and C. angorae (Hanko, 1925), have been studied for the presence of parasitic nematodes in Firmz Stream, K. Mara, Goksu River, Antalya, in the Anatolian Region of Turkey. Only a species of the genus Rhabdo-chona was found in intestines and identified as R. fortunatowi Dinnik, 1933. Totally, 104 specimens of R. fortunatowi infected 19 out of 99 individuals of C. caelestis (prevalence 19.1 %, mean intensity 5.4). In C. angorae, 40 specimens of R. fortunatowi infected 15 out of 178 fish individuals (prevalence 8.4 %, mean abundance 2.6). Prevalence and intensity of R. fortunatowi infection were calculated across the seasons as well as in age groups and sexes of hosts. The present study provides the first record of R. fortunatowi in Turkey and the first host records of this parasite in both C. caelestis and C. angorae, thus expanding the known geographical and host range of this nematode species.

(TÜBİTAK, 2011) Emre, Yılmaz; Emre, Nesrin; Aydoğdu, Ali; Altunel, Fayik Naci; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Biyoloji Anabilim Dalı.; Uludağ Üniversitesi/Mustafakemalpaşa Meslek Yüksek Okulu.; 6701819349; 7801410280
A total of 65 individuals from 3 different fish species, Capoeta antalyensis (n: 15), Aphanius mento (n: 29), and Pseudophoxinus battalgil (n: 21), were examined for helminth parasites (Nemathelminthes) between May and July of 2009. A total of 123 parasites of 3 species were found in these fish, consisting of 3 nematodes: Rhabdochona denudata, Eustrongylides excisus larvae, and Contracaecum sp. larvae. Among these species, R. denudata was recorded in the intestine of C. antalyensis, with a total of 92 parasites found in 13 of the 15 C. antalyensis examined. The overall prevalence of this species was 86.6%. Two further species of nematodes, Contracaecum sp. larvae and E.. excisus larvae, were found in the abdominal cavities of P battalgil and A. mento, respectively. Contracaecum sp. larvae were found in 10 of 21 fish examined and a total of 29 specimens were recorded, making the overall prevalence of this species 47.6%. Only 2 E. excisus larvae were found in 2 of the 29 fish examined. This study provides the first ichthyoparasitological data for these host fish species in Turkey, and the occurrence of R. denudata in C. antalyensis and Con tracaecum sp. larvae in P battalgil are considered to be new host records for these fish species.

(Springer, 2015-03-01) Emre, Yılmaz; Emre, Nesrin; Aydoğdu, Ali; Buselic, Ivana; Smales, Lesley R.; Mladineo, Ivona; AYDOĞDU, ALİ; Uludağ Üniversitesi/Mustafakemalpaşa Meslek Yüksekokulu; 0000-0003-2778-0273; JCO-3521-2023
Economically important sparid fish species, gilthead (Sparus aurata) and white seabream (Diplodus sargus) (Sparidae) are frequently parasitised by diplectanid monogeneans, known to induce severe losses in farming conditions. We have analysed population dynamic of two diplectanid species, Lamellodiscus echeneis and Lamellodiscus ignoratus (Monogenea: Diplectanidae) collected from two bream species in the Beymelek Lagoon (southwest coast of Turkey), comparing it between different host variables (fish size, age and sex) in order to have insight in parasites' ecology, important for managing parasitosis in the intensive aquaculture system. In seabream (N = 127), L. echeneis prevalence was 46.5 % (exact 95 % confidence limits 38.90-54.14), mean abundance 5.64 (bootstrap 95 % confidence limits 4.20-7.65) and mean intensity 12.14 (bootstrap 95 % confidence limits 9.49-15.59). In white seabream (N = 102), L. ignoratus prevalence was 24.5 % (exact 95 % confidence limits 16.53-34.03), mean abundance 1.73 (bootstrap 95 % confidence limits 0.98-3.21) and mean intensity 7.04 (bootstrap 95 % confidence limits 4.60-11.40). Parasites' parameters differed only between seasons in both hosts and between age categories in gilthead, but not in white seabream.

(Hindawi Ltd, 2018-02) De Leon, Perez Ponce Gerardo; Emre, Yılmaz; Emre, Nesrin; Aydoğdu, Ali; Yabacı, Ayşegül; Uludağ Üniversitesi/Sağlık Bilimleri Enstitüsü/Biyoistatistik Anabilim Dalı.; Uludağ Üniversitesi/Veteriner Fakültesi/Su Hayvanları Hastalıkları Anabilim Dalı.; 0000-0002-5813-3397; CAJ-5024-2022; 6701819349; 57195963234
Three species of cyprinids, i.e., Capoeta antalyensis (n=112), C. caelestis (n=99) and C. angorae (n=178) were collected from the Anatolian Region of Turkey to carry out this investigation. A total of 389 specimens of Capoeta were examined for Allocreadium isoporum infections throughout the four different seasons of 2012. The prevalence and mean intensity of infection of A. isoporum was investigated in relation to the host species, the seasons across the year, host size, and sex. Two-hundred and twenty-two specimens of a trematode identified as A. isoporum were found in these fishes. One-hundred seventy-eight C. angorae were caught, and 70 A. isoporum were recorded in 8 of 178 fish examined, with prevalence and mean intensity of infection of 4.49% and 8.7% parasites per infected fish, respectively. In the 112 specimens of C. antalyensis, 73 individuals of A. isoporum were found, with a prevalence of 19.6% and a mean intensity of 3.3. As for the infection in C. caelestis, a total of 79 specimens of A. isoporum were found in 17 of the 99 fish examined, with prevalence and mean intensity of infection of 17.1% and 4.6%, respectively. Prevalence and mean intensity values in relation to host size and sex, as well as the seasonality of infections was analyzed and the results were compared with other studies. The trematode A. isoporum is reported for the first time parasitising three endemic species of Capoeta spp. in Turkey, adding to the knowledge of geographical distribution and host range of this trematode species.
Prevalence and intensity of parasitic helminths of thicklip grey mullet Chelon labrosus in hosts in Beymelek Lagoon Lake in Antalya, Turkey, according to season, host size, age, and sex of the host
(TÜBİTAK, 2015-01-01) Aydoğdu, Ali; Emre, Nesrin; Emre, Yılmaz; AYDOĞDU, ALİ; Uludağ Üniversitesi/Mustafakemalpaşa Meslek Yüksekokulu.; 0000-0003-2778-0273; JCO-3521-2023
In this study, helminth parasites of the thicklip grey mullet (Chelon labrosus) in Beymelek Lagoon, Antalya (Turkey) were studied to determine the effect of seasonal changes and host size, age, and sex on the incidence of parasitic helminth infection. Three helminth species were identified: Ligophorus angustus Euzet & Suriano 1977 (Monogenea) on the gills, and Saccocoelium obesum Looss, 1902 (Digenea) and Neoechinorhynchus agilis (Rudolphi, 1819) (Acanthocephala) in the intestine. Among these species, S. obesum was the most common species, with an overall prevalence and mean intensity of 42.7% and 13.6 +/- 12.5 parasites/fish, respectively. L. angustus was the second most prevalent parasite, with an overall prevalence of 21.3%. The third most prevalent parasite was N. agilis, with an overall prevalence and mean intensity of 12.6% and 3.6 +/- 2.1 parasites/fish, respectively. Regarding the effect of seasonal changes, the prevalence and mean intensity of S. obesum was highest in the summer and spring, respectively. For L. angustus, while the highest prevalence was observed in winter (40.6%), this species was not recorded in summer. The prevalence of N. agilis was rather low (41.6%) in spring, and this species was also not detected in summer. With regard to host size-related incidence, the differences in the abundance of the 3 species among 4 size classes were not significant (P > 0.05). In contrast, there were significant differences in the abundance of N. agilis among the age groups (P = 0.33). As for the infrapopulations of the parasite species depending on the host's sex, significant differences were found in the infrapopulations of L. angustus and S. obesum between the sexes (P < 0.001 and P = 0.007, respectively).
Two new Dactylogyrus species (Monogenea: Dactylogyridae) D. angorae and D. turcicus from Capoeta angorae and C. mauricii endemic fishes in Turkey
(Springer, 2015-03-01) Aydoğdu, Ali; Molnar, Kalman; Emre, Yılmaz; Emre, Nesrin; AYDOĞDU, ALİ; Uludağ Üniversitesi/Mustafakemalpasa Meslek Yüksekokulu.; 0000-0003-2778-0273; JCO-3521-2023
Two new Dactylogyrus spp., D. angorae and D. turcicus have been described from the gills of the endemic cyprinid fishes, Capoeta angorae and C. mauricii from the Anatolian Region of Turkey. The shape of the anchors, hooks and the copulation organ of both species differ from those of the Dactylogyrus spp. found on other Capoeta species known from the Ponto-Caspian and Tigris-Euphrates regions.
Two new host records for pomphorhynchus laevis (Müller, 1776) (Acanthocephala) recorded from Antalya, Turkey: Small bleak (Alburnus baliki Bogutskaya, Küçük & Ünlü, 2000) and Antalya barb (Capoeta antalyensis Battalgil, 1944)
(TÜBİTAK, 2011) Emre, Yılmaz; Emre, Nesrin; Küçük, Fahrettin; Aydoğdu, Ali; Uludağ Üniversitesi/Mustafakemalpaşa Meslek Yüksek Okulu.; 6701819349
Acanthocephalan Pomphorhynchus laevis specimens are reported in Alburnus baliki and Capoeta antalyensis caught between May and July of 2009 in streams discharging into Antalya Bay. The total prevalence rate for P. laevis was 78.5% and 60% in A. baliki and C. antalyensis, respectively. A total of 28 A. baliki were caught, and 74 P. laevis were recorded in 22 of the 28 fish examined. As for the occurrence of P. laevis in C. antalyensis, a total of 15 fish were caught, and a total of 25 individuals were found in 9 of the 15 fish examined. This finding constitutes the first record of this helminth parasite in either fish species, and the host fishes represent 2 new host records for P. laevis.
