One of ways for conservation of sturgeon fish is performance of artificial propagation. In order to improve of incubators is important. At present for incubation of sturgeon eggs utilize from Yushchenko(Y) incubator. In 2005, Azarakhsh(A) incubator was made in Iran, for comparison of efficiency with Yushchenko incubator on four Acipenser persicus brood stocks with emphasis on evaluation parameter of fertilization percentage in blastula stage( A=96.2 , Y=90.2 ), the mortality percentage of larva before ( A=5.4, Y=10.6 ),and after ( A=8.6, Y=16.4 ) of active feeding and survival (A=86, Y=73) were occurred. In this survey the Azarakhsh incubator was better than Yshchenko incubator these issues demonstrated. The advantage of Azarakhsh incubator includes in less noise in activity and get out automatically from incubator vessel.
