length weight relationships of vimba vimba persa were studied. for this purpose 174 fish samples were collected by gill nets, beach seine and purse seine from march through june 2008 at two guilan fisheries catch stations of guilan located in anzali- kiyashahr regions. samples were immediately transferred to the laboratory of fish biology at university of guilan for further analyses. length, we...

Besides traditional methods based on morphological characters, electrophoretic such as SDS-PAGE are preferred by taxonomists to make the right decision in species identification process. In addition, effect of environmental factors, pH, salinity, heat, and temperature protein profiles essential various studies. this study, we aimed determine degree relationship some fish species, Squalius lepid...

Examination of the original literature concerning species of Philometra (Philometridae, Dracunculoidea) parasitic in the abdominal cavity of European cyprinids revealed that P. abdominalis Nybelin, 1928 is a junior synonym of P. ovata (Zeder, 1803), a parasite of cyprinids of the genera Gobio, Phoxinus and Leuciscus. The valid name of the species parasitizing cyprinids of the genera Abramis, Ru...

the chromosome number and type as well as karyotype in vimba vimba persa were studied. a total of 200 larvae and 10 fingerlings of this species with an average weight of 30.2g obtained from shahid ansari fish hatchery. to arrest mitosis in metaphase, larvae under study were placed in a 0.05% solution of colchicine for a period of 6h while the fingerlings were given an intramuscular injection of...

 Population genetic structure of Vimba vimba persa was investigated using microsatellite markers from 40 regions along the Iranian coastline of the Southern Caspian Sea (Anzali lagoon and Havigh River in Gilan province, BabolRoud River in Mazandaran province and GorganRoud River in Golestan province). Genomic DNA from 121 specimens was extracted from fin tissue by the Phenol-Chlorophorm method ...

Abstract The aim of this study was to compare the susceptibility body deformities in juveniles 13 common European cypriniform fish, caused by intensive feeding with same commercial dry diet administered at 25°C according a similar schedule. final share individuals malformations differed considerably among species and 0.0-87.0%. Unaffected were only Barbus barbus (L.), Chondrostoma nasus Cyprinu...
