In this study, we have conducted an investigation on the brood stocks of 17 Gattan, presumably a rare native economic fish, at the Institute of Aquaculture in South of Iran and the Native fishery reproduction center of Dashte Azadegan. The measurements of live samples were as follows:  average weight, 25/1±559/3g. the average length, 45/9±4/001cm the average fork length, 49/1±4/2cm the average of total length, 53/5±4/9cm. Also, the average duration of sperm motility was reported as 309/2±64/5 seconds, mean sperm density was 47/5±16/3, the PH average of semen 7/6±0/9, and the average percent of sperm atrocity 45/2±15/8%. In addition, the average glucose, cholesterol, and the total protein semen in sequence are as follows 23/3±1/0, 51/76±28/8, and 1/1±0/9mg/DL. Furthermore, the averages of sodium, potassium, magnesium, calcium and phosphorus levels of semen were reported as follows: 432/4±79/22, 108/8±20/26, 2/7±0/6, 0/7±0/2, and 15/8±3/1mm/l. Additionally, the sperm head length was 1/3±0/3 micron, the average length of agella 2/3±0/7micron, and the average total length of the sperms was 3/7±1/0. Overall, the results from this study have provided necessary information to illustrate that Gattan sperm cryopreservation is successful at the time of sperm motility and sperm concentration
