Freshwaters, Vol. 25, No. 1, pp. 1-10, 8 figs., 2 tabs., August 2014 © 2014 by Verlag Dr. Friedrich Pfeil, München, Germany – ISSN 0936-9902 Acanthobrama thisbeae, a new species of bream from southern Anatolia, Turkey (Teleostei: Cyprinidae) Jörg Freyhof* and Müfit Özulug** Acanthobrama thisbeae, new species, is described from the lower Ceyhan and Orontes Rivers in Turkey. It is dis- tinguished from other species of the genus by having 73-86 + 3-4 scales along the lateral line, a thin and short last 1 unbranched dorsal-fin ray, flank scales with a crenulated posterior margin, and 14-16 /2 branched anal-fin rays. Acanthobrama orontis is a valid species distributed in the Orontes, Ceyhan and Seyhan rivers. Eleven species are recognised as valid in the genus Acanthobrama (A. centisquama, A. hadiyahensis, A. lissneri, A. marmid, A. microlepis, A. orontis, A. persidis, A. telavivensis, A. thisbae, A. tricolor, A. urmianus). Acanthalburnus is treated as a synonym of Acanthobrama. Introduction Bostancı (2006) studied the fishes of the Ceyhan and did not record this species. As one of the two Three species of Acanthobrama are known from species we recorded had more scales along the Turkey: A. centisquama from the Orontes [Asi] lateral line, we first guessed that this might be drainage, A. marmid from the Qweik, the Euphra- A. centisquama, a species known only from the tes and the Tigris drainages, and A. microlepis Orontes drainage but not reported for more than from the Kura and the Arax drainages.

The parasitic fauna included two myzozoans, one choanozoan, seven ciliophorans, 24 myxozoans, eight trematodes, 34 monogeneans, 12 cestodes, 11 nematodes, five acanthocephalans, two annelids and nine crustaceans. The infection with some trematodes and nematodes occurred with larval stages, while the remaining infections were either with trophozoites or adult parasites. Among the inspected fishes, Cyprinion macrostomum was infected with the highest number of parasite species (29 parasite species), followed by Carasobarbus luteus (26 species) and Arabibarbus grypus (22 species) while six fish species (Alburnus caeruleus, A. sellal, Barbus lacerta, Cyprinion kais, Hemigrammocapoeta elegans and Mastacembelus mastacembelus) were infected with only one parasite species each. The myxozoan Myxobolus oviformis was the commonest parasite species as it was reported from 10 fish species, followed by both the myxozoan M. pfeifferi and the trematode Ascocotyle coleostoma which were reported from eight fish host species each and then by both the cestode Schyzocotyle acheilognathi and the nematode Contracaecum sp.

  • A Bibliography of the Fishes of the Tigris-Euphrates Basin
    A Bibliography of the Fishes of the Tigris-Euphrates Basin Bibliographie der Fische des Euphrat - Tigris - Beckens by Brian W. Coad and Lalth A. J. al·Hassan Introduction The Tigris-Euphrates basin is the major drainage basin of the Middle East, flowing through Turkey, Syria, Iraq and Iran. Its ichthyofauna provides a useful source of food and has been studied by biologists and systematists. The literature on this fauna is scattered through journals and books published in the Middle East and in many foreign countries and this is the first attempt to bring it all together. The bibliography comprises the principal systematic, distributional and biological works on the freshwater fishes ofthe Tigris-Euphrates basin. Some extralimital papers are included to facilitate study of this fauna as are revisio­ nary works which have an application to this basin. A more extensive bibliography on the fishes of Iran and their environ­ ment is in preparation (CoAD, MS). CoAD and KURU (1986) provide a bibliography on the fishes ofTurkey. Usually, the titel was cited in its original language. How­ ever, for articles in Arabic and Russian the title was translated into English or, if available, the title of the English summary was used.

  • Phylogenetic Relationships and Biogeographical Patterns in Circum
    Perea et al. BMC Evolutionary Biology 2010, 10:265 http://www.biomedcentral.com/1471-2148/10/265 RESEARCH ARTICLE Open Access Phylogenetic relationships and biogeographical patterns in Circum-Mediterranean subfamily Leuciscinae (Teleostei, Cyprinidae) inferred from both mitochondrial and nuclear data Silvia Perea1*, Madelaine Böhme2, Primož Zupančič3, Jörg Freyhof4, Radek Šanda5, Müfit Özuluğ6, Asghar Abdoli7, Ignacio Doadrio1 Abstract Background: Leuciscinae is a subfamily belonging to the Cyprinidae fish family that is widely distributed in Circum-Mediterranean region. Many efforts have been carried out to deciphering the evolutionary history of this group. Thus, different biogeographical scenarios have tried to explain the colonization of Europe and Mediterranean area by cyprinids, such as the “north dispersal” or the “Lago Mare dispersal” models. Most recently, Pleistocene glaciations influenced the distribution of leuciscins, especially in North and Central Europe. Weighing up these biogeographical scenarios, this paper constitutes not only the first attempt at deciphering the mitochondrial and nuclear relationships of Mediterranean leuciscins but also a test of biogeographical hypotheses that could have determined the current distribution of Circum-Mediterranean leuciscins. Results: A total of 4439 characters (mitochondrial + nuclear) from 321 individuals of 176 leuciscine species rendered a well-supported phylogeny, showing fourteen main lineages. Analyses of independent mitochondrial and nuclear markers supported the same main lineages, but basal relationships were not concordant. Moreover, some incongruence was found among independent mitochondrial and nuclear phylogenies. The monophyly of some poorly known genera such as Pseudophoxinus and Petroleuciscus was rejected. Representatives of both genera belong to different evolutionary lineages. Timing of cladogenetic events among the main leuciscine lineages was gained using mitochondrial and all genes data set.

Çiçek, E-mail: [email protected] Received: 24. August 2015 / Accepted: 16. October 2015 / Available online: 20. November 2015 / Printed: December 2015 Abstract. The current status of the inland waters ichthyofauna of Turkey is revised, and an updated checklist of the freshwater fishes is presented. A total of 368 fish species live in the inland waters of Turkey. Among these, 3 species are globally extinct, 5 species are extinct in Turkey, 28 species are non-native and 153 species are considered as endemic to Turkey. We recognise pronounced species richness and a high degree of endemism of the Turkish ichthyofauna (41.58%). Orders with the largest numbers of species in the ichthyofauna of Turkey are the Cypriniformes 247 species), Perciformes (43 species), Salmoniformes (21 species), Cyprinodontiformes (15 species), Siluriformes (10 species), Acipenseriformes (8 species) and Clupeiformes (8 species). At the family level, the Cyprinidae has the greatest number of species (188 species; 51.1% of the total species), followed by the Nemacheilidae (39), Salmonidae (21 species), Cobitidae (20 species), Gobiidae (18 species) and Cyprinodontidea (14 species).
