| Abstract: | Early germ cell development in Persian sturgeon appears to be faster in the marine environment than in aquaculture conditions.
Adaptation plasticity differs significantly for gonad formation and sex determination in the sturgeon fry and depends to differing
extents on the temperature. The sturgeon gonads are more sensitive to low temperatures on the early stages of sex determination
than in the period of gonad formation; the differences between sexes are preconditioned by the earlier start of sex determination
in females when compared to males. The rates of the early gonad and germ cell development in sturgeon are conditioned by its
reproduction season. In the population of the late spring race, the delay in both early sex determination and germ cell development
stays even for the ages of 1+, 2+, and 3+ when compared to the population of the early spring race. The biophysiological quality
of parents is transmitted to their offspring. |
