Abstract
The late sexual maturity in sturgeon and the absence of morphological differences between males
and females makes sex discrimination difficult. Identification of sex at an early life stage is of high
interest in caviar production because it allows efficient selection of females. In this study, the genome
of 10 mature male and 10 mature female specimens of Persian sturgeon (Acipenser persicus)
and beluga sturgeon (Huso huso) were screened using AFLP and 100 primer combinations. Results
showed a total of 3771 and 3779 scoreable bands in A. persicus and H. huso, respectively.
Approximately 30% of markers in A. persicus and 29.6% H. huso were polymorphic. No sex specific
makers were identified. The results of the present study suggest that the sex chromosomes are
not extensively differentiated in sturgeon species, or possibly the methods utilized were not sufficiently
sensitive to recognize them.
