    Abstract:

    This study aimed to understand the chromosome characteristics of Silurus lanzhouensis, therefore providing basic data for cytogenetic and artificial breeding studies of this species. The chromosomes of cultured kidney cells of Silurus lanzhouensis prepared by air-drying technique were elucidated. The results showed that: Silurus lanzhouensis has 2n=58 chromosomes; the karyotype formula is 2n=20m 18sm 16st 4t; the total number of arms (NF) is 96. Compared with the karyotype of other fishes, it was concluded that Silurus lanzhouensis is a more ancestral group among fishes of Silurus.
