because of limits in applicable karyological techniques and also the presence of a large number of small chromosomes in penaiedae family, the study on the number, structure, and the formula of the chromosomes in these shrimps is difficult. the present cytogenetic study was conducted on penaeus (fenneropenaeus) merguiensis native to persian gulf and oman sea by preparing spreads from various ear...

  Preparation of chromosome spreads and karyotype analysis in Blicca bjoerkna transcaucasica were carried out using 0.01% solution of colchicines and Phytohaemagglutinin (PHA) (20 µg g-1 body weight). The gill and kidney tissues were collected and let to stand in a hypotonic solution of 0.075 M KCl and then treated with a fixative (Carnoy's solution) in three steps. The chromosomes spreads were...

Karyological characteristics of bighead goby (Neogobius kessleri) in the Caspian Sea were studied by examining 30 metaphase chromosome spreads from the kidney tissue of 10 specimens. The chromosome number of this species was found 2n=46 and the arm number as NF=46. The prepared karyotype of this species consisted of 23 pairs acro-telocentric (a-t) chromosomes. The chromosomal formula can be sta...

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...

in the present study karyotype of mazani river buffalo was studied in comparison with those of azeri buffalo populations from iran. blood samples were taken from ten (5 males and 5 females) mazani buffaloes and thirty (15 males and 15 females) azeri buffaloes. the mazani buffaloes belong to mazendaran province and azeri buffaloes belong to west and east azerbaijan and ardebil provinces. blood l...

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 a...

In this study, for the first time in Iran, the karyotype of bigmouth Lotak, Cyprinion macrostomum Heckel, 1843, was investigated through examining metaphase chromosomes of seven fish with mean weight 30±5g caught by electrofishing from Godarkhosh River in Ilam Province. To stimulate cell divisions, fish were injected intraperitoneally two times by phytohemagglutinin (PHA). The cell divisions we...
