Persian sturgeon (Acipenser persicus) is one of the most valuable species in the southern parts of the Caspian Sea. Regrettably, however, the population of them currently declined due to poaching and overfishing for their meat or caviar harvesting, environmental pollution and destruction of spawning grounds in the Caspian Sea. The Persian sturgeon has been considered an endangered species in IUCN Red List (IUCN, 2012) and thus for five decades, the conservation of Persian sturgeon is launched to carry out by artificial propagation through applying appropriate larval rearing techniques and supplying fingerlings.
