چکیده
In this study, the karyotypic characteristics of Chondrostoma regium (Heckel, 1843) have been investigated. Fish samples were caught from Karasu River (Euphrates Basin) with fishing net. The live fish transported to laboratory and kept in aerated aquaria before analyses. karyotype analysis was performed kidney gill epithelium cells. It determined that C. had 2n=50 chromosomes. detail, formula as 9 metacentric, 7 submetacentric, 1 subtelocentric 8 telocentric chromosome pairs (18M+14SM+2ST+16T), fundamental arm number calculated 82. Constitutive heterochromatin regions on telomeres Nuclear orgnizer detected 21st chromosome. Karyotype symmetry/asymmetry index 2.32. karyotypes cells same. No sex chromosomes cytologically detected.

The karyotypic characteristics of chub, Squalius cephalus have been investigated by examining metaphase chromosomes spreads obtained from gill and kidney tissues. The fish used in the study were caught with fishing nets from Dumlu Stream, one of the main tributaries of the Karasu River. The live fish were transported to the laboratory, kept in a well aerated aquarium before analysis and then...

Age, growth and reproduction were investigated for Chondrostoma regium, collected monthly (November 2007- August 2008) from the Dimeh Spring region, Zayandeh Roud River, Iran. The maximum age of collected female and male fish were estimated based on scale increments as five and four years respectively. Von Bertalanffy growth equations were calculated as L_t=246[1-e^(-0.206(t-0.034))], W_t=163.2...
