During last decades, stocks of sturgeons were proper and there were enough adult fishes for obtaining pituitary gland. But, during recent years, their stocks decreased sharply, so fish farms cannot obtain proper number of pituitary gland, so they had to find an alternation and solve the problem. Result of this study represents application of LHRH-A2 (Luteinizans Hormonum Releasans Hormonum A2 (LHRH-A2) Pro Injection) as an alternative of pituitary gland in artificial propagation of Persian sturgeon.Results showed that LHRH-A2 induced final maturation and ovulation in dosages of 3.5, 7, 8 and 10 µg/kg of body weight of females, successfully. Finally, it was concluded that LHRH-A2 is a proper alternation for pituitary gland in artificial propagation of Persian sturgeon.
