Revision of Parasitic Helminths Reported in Freshwater Fish From Turkey with New Records

Abstract This new checklist is an update of helminths of freshwater fish from Turkey. The last publication of a checklist of helminth parasites of freshwater fish in Turkey was over 11 years ago (Öktener, 2003), and there have been a number of new records. This update includes additional records and allows for the correction of errors and omissions that were present in the preceding version. The revision literature indicated the occurrence of 123 parasite species which included 60 monogeneans, 20 digeneans, 20 cestodes, 11 nematodes, seven acanthocephalans, five annelids from 71 different wild fish (64 native, four transitional, three introduced fish) species from freshwater in Turkey. Parasites not identified to species level are listed separately, and not included in the resulting comments, because of reporting different host species. Cyprinidae, with 50 species, is the dominant family among the examined fish with regard to species diversity Resumen Revisión de parásitos helmintos reportados en peces de aguadulce en Turquía, con nuevos registros. Se realizó una actualización del elenco de especies de helmintos parásitos de peces de agua dulce de Turquía. Desde la publicación del último listado de parásitos helmintos de peces dulceacuícolas, hace 11 años (Öktener, 2003), han habido cantidad de nuevos registros. Esta actualización incluye a dichos registros, lo cual permitió la corrección de aquellos errores y omisiones que se cometieron en la versión anterior del listado. La literatura revisada indica la ocurrencia de 123 especies parásitas que incluyen 60 monogeneos, 20 digeneos, 20 céstodos, 11 nemátodos, siete acantocéfalos y cinco anélidos colectados en 71 especies de peces de agua dulce en Turquía (64 especies nativas, cuatro transicionales y tres introducidas). Los parásitos no identificados a nivel especie se enlistan separadamente y no se comentan en los resultados, debido a que son reportados en distintas especies de hospederos. Los ciprínidos, con 50 especies, es la familia dominante entre los peces examinados en cuanto a diversidad específica Rezumat Revizuire a viermilor paraziți raportați la specii de pești de apă dulce din Turcia, cu noi înregistrări. Această listă nouă de specii este rezultatul revizuirii parazitării helmintice la speciile de pești de apă dulce din Turcia. De la publicarea primei versiuni în urmă cu peste 11 ani (Öktener, 2003), au mai fost semnalate și alte specii. Prezenta versiune include și semnalările ulterioare și permite corectarea erorilor și omisiunilor din prima versiune. Literatura utilizată a indicat prezența a 123 de specii parazite care au inclus 60 specii monogenee, 20 specii de digenee, 20 de cestode, 11 nematode, șapte acanthocephali, cinci annelide, iar speciile gazdă sunt în număr de 71 (specii sălbatice dulcicole) din care 64 sunt pești autohtoni, patru de tranzit și trei specii introduse. Paraziții care nu au fost identificați la nivel de specie sunt indicați într-o listă separată fără a include comentarii, deoarece se raportează la specii gazdă diferite. Din punct de vedere al diversității speciilor studiate, familia de pești dominantă este cea a Cyprinidaelor cu 50 de specii investigate parazitologic

Confirmed Occurrence of Caligus mugilis Brian (Copepoda, Siphonostomatoida; Caligidae) with Morphological Characters in Turkish Marine Waters

The aim of this study is to determine Caligus mugilis including morphological characters on Mugil cephalus from Bandırma Bay in Turkey. The flathead grey mullet, Mugil cephalus were examined for the ectoparasites in 2016. Caligus mugilis Brian, 1935 (Copepoda, Siphonostomatoida, Caligidae) is confirmed for the first time in Turkish marine waters. Also, some morphological characters of this parasitic copepod are described. All parasites were firmly attached to the gill filaments of the host. Parasite prevalence, mean intensity and mean abundance were 9.3%, 1, 0.09, respectively. It should be noted that Caligus mugilis was reported by some researcher in 1989, however there was uncertainty about the occurrence of Caligus mugilis in Turkey. This controversial issue is cleared with this study.

Review of Parasitic Copepods Recorded in Fish from Turkey

Abstract This review presents the occurrence of 62 parasitic copepod species from 72 different fish species (64 wild, two cultured, seven from aquarium) from Turkey. The parasite species list is arranged by providing parasite species name, host fish, location of host fish capture and author, date of published record. All parasites and their hosts are confirmed with the recent systematic accounts and full taxonomic account according to literature and internet database. Siphonostomatoida with 47 species and Caligidae with 12 species are the dominant order and family among parasitic copepoda with regard to species diversity, host distribution and location.

Morphology of Lernanthropinus trachuri ()(Copepoda, Siphonostomatoida, Lernanthropidae) from Bandirma Bay(Turkey)

Abstract The parasitic copepod, Lernanthropinus trachuri (Brian, 1903) (Copepoda, Siphonostomatoida, Lernanthropidae)was found on the Mediterranean horse mackerel, Trachurus mediterraneus in Bandırma Bay, Turkey. The aim of this study is to present female Lernanthropinus trachuri with morphological characters with photos from Turkey. The details unseen in photos were supported with drawings. All parasites were firmly attached to the gill filaments of the host. This parasite is also specific for the genus Trachurus (Costa et al 2017). Therefore, this parasite may use as biomonitor or tag species for fish stock studies in Turkey.

Occurrence of Chondracanthus merluccii (Holten, 1802) and Chondracanthus angustatus Heller, 1865 (Copepoda: Chondracanthidae) in Turkish Marine Waters

The Sea of Marmara being an unique inland sea displays the transitional environment between the Black Sea and the Mediterranean Sea. There is limited studies on the parasitic copepods of fish in the Sea of Marmara. Chondracanthus merluccii (Holten, 1802) and Chondracanthus angustatus Heller, 1865 (Copepoda: Chondracanthidae) are reported for the first time in Turkey. C. merluccii were found on the upper and under surface of the mouth, upperside of the tongue, through teeth of the European hake, Merluccius merluccius (L.), while C. angustatus on the gill rakers of the stargazer, Uranoscopus scaber L. captured from the Sea of Marmara. Morphological characters of Chondracanthus merluccii and Chondracanthus angustatus were presented with photos. This study contributes new geographical distribution for these parasites.

Redescription of Elthusa sinuata (Koelbel, 1879) Comb.Nov. (Isopoda, Cymothoidae) Parasitizing the Red Bandfish in Turkey

Livoneca sinuata Koelbel, 1879 (Isopoda, Cymothoidae) is known from the Mediterranean Sea. In this study, this species is redescribed and transferred to the genus Elthusa according to the current status of this: body weakly twisted, antennula shorter than antenna, posterior margin of cephalon not trilobed, pleonite 1 slightly narrower than pleonite 2, maxilliped with oostegital lobe and pleopods all lamellar, without lobes or folds. This species was collected on the red bandfish, Cepola macrophthalma, and reported for the first time in the Sea of Marmara, Turkey. The species is also photographed for the first time on the host.

The Sea of Marmara: New Locality for Lepeophtheirus europaensis Zedam, Berrebi, Renaud, Raibaut and Gabrion, 1988 (Copepoda, Siphonostomatoida, Caligidae) from Turkey

Abstract Lepeophtheirus europaensis Zeddam, Berrebi, Renaud, Raibaut and Gabrion, 1988 (Copepoda, Siphonostomatoida, Caligidae) an ectoparasite of flatfishes, was reported for the first time in the Sea of Marmara Coasts. Some morphological characters of this parasitic copepod are given using original photographs and drawings. The general morphology, the mouth parts (antenna, mandible, maxillule, maxilla, and maxilliped), the outgrowth developed between the post-antennary process and the antenna, the setal and spinal formula from first leg to fourth leg in this study are compatible according to the specific literature.

Some Morphological Characters of Female of Mothocya epimerica Costa, 1851 (Flabellifera: Cymothoidae) from Sea of Marmara

Abstract Mothocya epimerica Costa, 1851 (Flabellifera: Cymothoidae) is a cymothoid parasite of fishes belonging to Atherinidae (Atherina hepsetus, Atherina boyeri) from Mediterranean Sea, Black Sea and Atlantic Ocean. Öktener and Sezgin (2000) recorded this parasite for the first time in Turkey. The mentioned authors presented some morphological characters, although, some characters are not explained in the publication. Some morphological characters seen on the mandible, maxilliped, maxilla, maxillue and the spines on pleopods of the female of M. epimerica are shown. The characters presented in our study are based on the drawings made from collected specimens.

Cases of External Myiasis Caused by Diptera (Sarcophaga sp.) on Three Cyprinid Species

Sarcophaga sp. caused external myiases on three cyprinid species caught from Atatürk Dam Lake, Turkey) in July 2006. A total of 130 live dipteran larvae were collected from the body surfaces of Cyprinus carpio L., 1758, Barbus grypus Heckel, 1843, and Capoeta trutta Heckel, 1843. There was 100% infestation of all three species of fish, with a mean intensity of 13.6 for C. carpio , 5.6 for B. grypus , and 4.3 for C. trutta . The myiases were probably accidental infections on stressed and immobilized fishes.
