“…Additionally, the observed 16S rDNA sequence divergence values (0.96-1.35%, mean 1.19%, between C. tinca and C. banarescui haplotypes, and 0.96-1.54%, mean 1.4%, between Capoeta tinca and Capoeta sp. haplotypes) represent some of the lowest values reported among other congeneric freshwater fish species (1.4-16%) (STEINKE et al 2005, LI et al 2005 as well as within the reported ones (0.5 to 9.4%) for species within the genus Capoeta from central Anatolia recorded by TURAN (2008). The degree of sequence divergence between these two species is therefore comparable to that between other well accepted species.…”

The genetic discrimination of two species of the genus Capoeta, C. tinca (Heckel, 1843) and C. banarescui Turan et al., 2006, which is represented by many endemic species in Anatolian Turkey, has been investigated by analysing the partial 16S ribosomal DNA gene (525 bp). A total of 85 fish was sampled from two localities in the Marmara basin and 5 localities in the Black Sea basin. The amount of 16S rDNA sequence divergence separating these two taxa (mean 1.19%) is within the range observed for 16S rDNA variation between other species of freshwater fishes. The derived haplotypes (h: 28) were strictly local and were not shared between species or populations within species. Three types of phylogenetic tree (Bayesian, MP and ML) clearly showed C. banarescui and C. tinca as distinct species separated with significant bootstrap values (BI:94, MP:88, ML:81), confirming previous conclusions based on morphometric and meristic characters. Furthermore, four novel SNPs were identified, allowing discrimination between two species. AMOVA tests revealed that populations of Capoeta in Northeastern Anatolia can be divided into two main groups: Coruh River group, including SVS, TRT and ISP populations, and Yesilirmak-Harsit group, consisting of ALC and HRS populations. These results indicate the effectiveness of mitochondrial 16S rDNA gene sequences for both species identification and the phylogenetic analysis of Capoeta species.

As presently recognized, the genus Capoeta includes 24 species, nine of which are known to occur in Iran (Capoeta aculeata, Capoeta capoeta, Capoeta buhsei, Capoeta damascina, Capoeta fusca, Capoeta heratensis, Capoeta mandica, Capoeta saadii and Capoeta trutta) and are distributed in almost all Iranian basins except Sistan and Mashkid. Capoeta coadi sp. n. is a new species from the Karun River, southern Iran, draining into the Arvand Rud (Shatt al-Arab) which drains into the Persian Gulf. It is distinguished from all other species of Capoeta by the combination of the following characters: elongate and usually cylindrical body; 8–9 branched dorsal-fin rays; last unbranched dorsal-fin ray weakly to moderately ossified and serrated along 1/3–2/3 of its length; scales small; 70-84 in lateral line (total); 12–17 scales between dorsal-fin origin and lateral line; 9-11 scales between anal-fin origin and lateral line; 26–32 circum-peduncular scales; 10–13 gill rakers on lower limb of first gill arch; 45–47 total vertebrae; one posterior pair of barbels; bright golden-greenish or silvery body coloration in life; length of the longest dorsal-fin ray 15–22% SL; head length 23–26% SL; mouth width 7–10% SL. Capoeta coadi is also distinguished from all other congeners in the Iranian drainages by fixed diagnostic nucleotide substitutions in the mtDNA COI barcode region and cyt b. It is nested in the Capoeta damascina species complex.

“…The predominant fish in this river is Siah Mahi, Capoeta capoeta gracilis (Keyserling, 1861). The genus Capoeta contains potamodromous cyprinid fish, inhabiting both lotic and lentic habitats (Samaee et al, 2006) and generally occurring in lakes and streams with fast-and slow-flowing waters (Turan, 2008). They are also distributed throughout the freshwater river systems of the South Caspian Sea basin (Abdoli et al, 2008;Samaee et al, 2009).…”

Detection of morphometric differentiation between isolated up- and downstream populations of Siah Mahi (Capoeta capoeta gracilis) (Pisces: Cyprinidae) in the Tajan River (Iran)

et al. 2011

It has been postulated that the building of the Shahid-Rajaei dam on the Tajan River around 1995 has lead to the morphological divergence of Siah Mahi Capotes capoeta gracilis (Pisces) of up-and downstream populations due to the isolation. A 13-landmark morphometric truss network system was used to investigate the hypothesis. Univariate analysis of variance showed significant differences between the means of the two groups for 45 standardized morphometric measurements out of 78 characters studied. In linear discriminant function analysis (DFA), the overall assignment of individuals into their original groups was 87.6%. The proportion of individuals correctly classified into their original groups was 90.3% for upstream and 83.7% for downstream population. The principal component analysis (PCA) scatter plot of individual component scores between PC1 and PC2 showed 121 fish specimens grouped into two areas but with a relativity high degree of overlap between two populations. Clustering analysis based on Euclidean square distances among groups of centroids using an UPGMA resulted into two main clusters indicating two populations of C. c. gracilis. The present study indicated the presence of two morphologically different populations of C. c. gracilis in the Tajan River across the Shahid-Rajaei dam, probably due to their limited downstream dispersal and the elimination of upstream migration altogether, due the construction of the dam.
