After anesthesia, using 1% clove oil solution, the specimens were fixed in 10% buffered formalin and transferred to the Ichthyology Museum of Isfahan University of Technology for further studies. The left sides of the specimens were photographed using a copy-stand equipped with a digital camera. To extract body shape data, 13 homologous landmark-points were digitized using tpsDig2 software. After GPA superimposing, the landmark data, were analyzed using Principal Components Analysis (PCA), Canonical Variate Analysis (CVA) and Cluster Analysis (CA) to explore the patterns of variation in their body shape. All multivariate analyses were computed using PAST software. The consensus configuration of populations was visualized using the wireframe graphs in MorphoJ to compare their shape difference. The PCA, CVA and CA showed differences among the populations, especially, between Konjancham and other populations. This result showed that geometric morphometric methods could separate trout barb populations of the Tigris River Basin from each other to a great extent. Potential factors contributing to the observed variations include differences in physicochemical parameters of rivers and geographic distance among the populations. However, for more details, molecular studies are needed. Key words: Cypriniformes, Geometry, Multivariate Analysis, Procrustes, Persian Gulf. Citation: Keivany, Y. & Arab, M. 2017.

Since the work of J.J. Heckel (1846-1849), the number of valid species has increased significantly and the systematic status of many of the species has changed, and reorganization and updating of the published information has become essential. Here we take the opportunity to provide a new and updated checklist of freshwater fishes of Iran based on literature and taxon occurrence data obtained from natural history and new fish collections. This article lists 288 species in 107 genera, 28 families, 22 orders and 3 classes reported from different Iranian basins. However, presence of 23 reported species in Iranian waters needs confirmation by specimens.

This study aimed to compare the body shapes of five populations of abu mullet, Planiliza abu (Heckel, 1843), in Bushehr basin using geometric morphometric method. Some 162 specimens from Hendijan, Genaveh, Helleh, Kaki and Mond rivers were used. Three morphometric characters, total length (TL), fork length (FL) and standard length (SL) were measured. Samples were photographed from the left side, then 18 landmarks were digitized using ImageJ software. Data obtained from Procrustes were analyzed by multivariate analysis using PCA and CVA. The results of PCA analysis showed significant differences between Kaki and other populations (P < 0.0001).

Email: [email protected] General Mixed Yule- Coalescent (GMYC) and Poisson Tree Process (PTP) as well as haplotype network analyses. Using the BEAST program, we also examined temporal divergence patterns of Capoeta. The monophyly of the genus and the existence of three previously described main clades (Mesopotamian, Anatolian- Iranian, and Aralo- Caspian) were confirmed. However, the phylogeny proposed novel taxonomic findings within Capoeta. Results of GMYC, bPTP, and phylogenetic analyses were similar and suggested that species diversity in Iran is currently underestimated. At least four can- didate species, Capoeta sp4, Capoeta sp5, Capoeta sp6, and Capoeta sp7, are awaiting description. Capoeta capoeta comprises a species complex with distinct genetic line- ages. The divergence times of the three main Capoeta clades are estimated to have occurred around 15.6–12.4 Mya, consistent with a Mio- Pleistocene origin of the di- versity of Capoeta in Iran. The changes in Caspian Sea levels associated with climate fluctuations and geomorphological events such as the uplift of the Zagros and Alborz Mountains may account for the complex speciation patterns in Capoeta in Iran.

Corresponding author: *E-mail: [email protected] Abstract The genus Capoeta in Iran is highly diversified with 14 species and is one of the most important freshwater fauna components of the country. Central Iran is a region with high number of endemism in other freshwater fish species, though the present species was recognized as C. aculeata (Valenciennes, 1844), widely distributed within Kavir and Namak basins. However previous phylogenetic and phylogeographic studies found that populations of Nam River, a tributary of the Hableh River in central Iran are different from the other species. In this study, the mentioned population is described as a new species based on morphologic and genetic characters. Keywords: Inland freshwater of Iran, Nam River, Algae-scraping cyprinid, Capoeta.

    Furhan T. Mhaisen & Kefah N. Abdul-Ameer Bull. Iraq Nat. Hist. Mus. (2014) 13 (1): 35-51 CHECKLISTS OF DIPLOZOID SPECIES (MONOGENEA) FROM FISHES OF IRAQ Furhan T. Mhaisen* and Kefah N. Abdul-Ameer** * Tegnervägen 6B, Katrineholm 641 36, Sweden ** Department of Biology, College of Education (Ibn Al-Haitham), University of Baghdad, Baghdad, Iraq. e-mail: [email protected] ABSTRACT Surveying 59 references concerning the occurrence of the monogeneans of the family Diplozoidae parasitizing fishes of Iraq showed the occurrence of 15 valid species of this family which included one species of Diplozoon, one species of Eudiplozoon and 13 species of Paradiplozoon. In addition to these species, some unidentified adult and larval (diporpa larvae) specimens of the genus Diplozoon were reported from 12 fish hosts among which four fish species showed no infection with any of the nominated diplozoid species while the others showed mixed diplozoid infections. These diplozoids were reported from 27 fish host species in Iraq. All the diplozoids were recorded from freshwater habitats except one Dipolzoon sp. which was recorded from a marine habitat. Hosts recorded for each of these diplozoids ranged from a minimum of one host in case of both P. ergensi and P. tadzhikistanicum to a maximum of 13 hosts in case of P. kasimii. Among the infected fishes, 13 hosts harboured only one diplozoid species each while a maximum of 10 diplozoid species were reported from both Aspius vorax and Cyprinion macrostomum. INTRODUCTION Members of the class Monogenea include small hermaphroditic flat worms that parasitize fishes and other aquatic animals. They infect fins, skin and gills of freshwater and marine fishes (Duijn, 1973).

  • Checklists of Parasites of Fishes of Salah Al-Din Province, Iraq
    Vol. 2 (2): 180-218, 2018 Checklists of Parasites of Fishes of Salah Al-Din Province, Iraq Furhan T. Mhaisen1*, Kefah N. Abdul-Ameer2 & Zeyad K. Hamdan3 1Tegnervägen 6B, 641 36 Katrineholm, Sweden 2Department of Biology, College of Education for Pure Science, University of Baghdad, Iraq 3Department of Biology, College of Education for Pure Science, University of Tikrit, Iraq *Corresponding author: [email protected] Abstract: Literature reviews of reports concerning the parasitic fauna of fishes of Salah Al-Din province, Iraq till the end of 2017 showed that a total of 115 parasite species are so far known from 25 valid fish species investigated for parasitic infections. 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.
