Artificial propagation of different kinds of commercial fish of the Caspian Sea, such as sturgeon fishes (specially Persian acetras Acipenser persicus Borodin, 1897) has been recover the stocks in the sea as the natural spawning places in the river has been destroyed in this area. At the present research the number and the quality of fingerlings during the release wad studied. 12361001 pieces of fingerlings 3315846, 7803455 and 1148700 in three center, Rajaei, Sad-e-voshemgir and Marjani respectively) were released in the rivers of Mazandaran and Golestan province. That consist of 87.7, 6.6, 3.3 and 2.4% of A. persicus, A. guldenstaedtii (Brandt, 1833) Huso huso (Linnaeus, 1758) and A. nudiventris (Iovetsky, 1826) respectively. The most important river were Gorgan-rood, Tajan, Larim and Goharbaran (8659377, 1453410, 1211875 and 743561 number, respectively). The average Of weight of above mentioned fish were also 2.55, 4.12, 3.40 and 3.09 gr, as well as 67.2, 40, 34.9 and 47.7% had less than 3 gr weight respectively. These fingerlings were reared in 205 hectare (65.5 he in Rajaei center and 139.5 he in Golestan province). In Rajaei center there was not only any sign or microbial contamination; Diplostumum and Dactylogyrous parasites but 36.7% of fingerlings of A. persicus was combinated to Tericodin.
