For this work after the artificial reproduction, spilling the eggs in the incubators, in 3 stages:
1- stage of the second division of mitosis
2- stage of final gastrula
3- the stage before division
Then, sampling from the eggs and after fixing them in %10 formalin, they studied under the loop, and healthy and unhealthy
eggs were divided. The results of the perish percentage of eggs from Acipenser persicus , in the mentioned stages, were %30 ,
%34 and %40 respectively, that of course these numbers are under the impression of several factors and for this reason , they
are different , in different conditions . According of this result, we can appoint that the eggs incubation is economical or not?
And is it better to evacuate incubators from the eggs with high perish percentage?
