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

In a parasitic survey of the native and introduced fishes in the Zayandehrud River, 5 Myxobolus spp. were found in the gills, fins and skin of examined fish specimens. They include M. varicorhini from fin and M. samgoricus from skin of Capoeta damascina, M. musajevi from gills of Capoeta capoeta gracilis, Myxobolus cristatus from Capoeta aculeata, and M. saidovi from Alburnus sp. Data on the lo...

this study was conducted to evaluate the morphological responses of two different species including capoeta gracilis and alburnoides eichwaldii due to construction of the tarik dam in the sefidrud river using geometric morphometric technique. for this purpose, a total of 80 specimens of c. gracilis and 60 specimens of a. eichwaldii were collected from upstream and down-stream of dam. the left s...

it has been postulated that the building of the manjil and tarik dams on sefidroud river has led to the body shape variation of capoeta gracilis in up- and downstream populations due to the isolation. in this study, geometric morphometric approach was used to explore body shape variations of capoeta gracilis populations in up- and downstream manjil and tarik dams in sefidroud river from south o...

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,...
