Traditionally, Capoeta populations from the southern Caspian Sea basin have been considered as Capoeta capoeta gracilis. Study on the phylogenetic relationship of Capoeta species using mitochondrial cytochrome b gene sequences show that Capoeta population from the southern Caspian Sea basin is distinct species and receive well support (posterior probability of 100%). Based on the tree topologie...
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 coadisp. n. is a new species from the Karun River,...
We evaluated the effects of the Shahid-Rajaei dam, 14 years after its construction, on morphometric and genetic divergence between up- and downstream populations of the Iranian fish Siah-Mahi (Capoeta capoeta gracilis). Sixty-six specimens were analyzed. There were significant differences between the 2 groups in the means of 16 morphometric characters (univariate analysis). In discriminant func...
The Middle East contains a great diversity of Capoeta species, but their taxonomy remains poorly described. We used mitochondrial history to examine diversity of the algae-scraping cyprinid Capoeta in Iran, applying the species-delimiting approaches General Mixed Yule-Coalescent (GMYC) and Poisson Tree Process (PTP) as well as haplotype network analyses. Using the BEAST program, we also examine...
112 specimens of capoeta capoeta gracilis from the shrioud river were examined. the prevalence and abundance of parasites were significantly higher in the area between the mouth to behind the opercle. susceptibility of infection was not significantly different between male and female fish. the prevalence of infection was the lowest in the largest length group. histopathological study revealed b...
این تحقیق از12 مرداد ماه سال 1389 تا 30 تیر 1390 در رودخانه بابلرود استان مازندران بر روی گونه سیاه ماهی جنس gracilis capoeta capoetaانجام گرفته است.نمونه برداری ها به صورت ماهانه با استفاده از الکتروشوکر صورت گرفت و در مجموع 307 عدد سیاه ماهی صید گردید.متغیرهای طول کل، طول چنگالی، طول استاندارد، وزن بدن، سن، جنسیت، وزن گناد و قطر تخمک اندازه گیری و ثبت شدند. برای تعیین سن از فلس ها استفا...
BACKGROUND The aim of this study was to detect the occurrence of parasites in fish in Armand River, Chaharmahal va Bakhtyari Province regarding the importance of native fish population in the river. METHODS The occurrence of parasites was investigated in 6 native fish (Capoeta capoeta, C. damascina, C. aculeta, Barbus barbulus, B. grypus and Glyptothorax silviae) collected from the current ma...
the aim of this study was to determine and compare the concentration of copper (cu) in liver and muscle of two fish species squalius cephalus and capoeta capoeta gracilis. the fish were caught in four sampling sites along tajan river, mazandaran province, northern iran. the concentration of cu was determined using flame atomic absorption spectrometry. there were significant differences (p
