Summary A study was conducted to ascertain the genetic structure and the level of heterozygosity of A cipenser persicus in the C aspian S ea. A total of 167 fish were randomly collected from T urkmenistan, R ussia and two regions of I ran. The number of alleles of eleven microsatellite markers ranged from 3 to 21 and the mean observed values of heterozygosity were 0.56 ± 0.20, 0.64 ± 0.14, 0.67 ± 0.16, and 0.64 ± 0.11. The observed heterozygosity was lower than the expected levels. The observed low genetic differentiation indicates that all populations are closely related. Hence, inbreeding is a potential problem, which should be taken into consideration in future breeding programs to avoid a further decline in genetic diversity.
