Abstract |
In the present study, we investigated the karyotype and chromosomal characteristic of
nucleolar organizing regions (NORs) in Labeo chrysophekadion from Mae khong River, Nong
Khai Province, Thailand. The metaphase chromosomes were prepared from kidney cells of five
male and five female fish. Conventional and Ag–NOR staining techniques were applied to the
chromosomes. Karyological analysis revealed that 2n= 50 and NF= 86. The karyotype of L.
chrysophekadion comprising five pair of metacentric, three pairs of submetacentric, ten pairs
of acrocentric and seven pairs of telocentric chromosomes. Thus, the chromosome formula
could be suggested as 2n= 50, 10m+ 6sm+ 20a+ 14t. There are two pairs of NOR– bearing
chromosomes which are located at the telomeric position of the short arm of the acrocentric
chromosome pair 12 and 13. The chromosome characters between male and female fish cannot
be distinguished by conventional and silver straining. The number of active NORs in
metaphase cell varies between two and four among the observed metaphase cells in the same
sample.
