This research was carried out major and trace elements (Ca++, Mg++, Na+, K+, Fe++ and Zn++) in seminal plasma and quality parameters of sperm (Volume, pH and spermatocrit of sperm, motility, duration and density of spermatozoa) of two different trout (Oncorhynchus mykiss and Salmo trutta fario) in a fish farm. As results, the levels of Ca++, Fe++ and volume of sperm between two species of trout were significant difference as statistically (p<0.05). We aimed to investigate performance and management status of male brood stocks in this fish farm. Finally, male brood stocks of this fish farm had very low quality parameters of sperm as normal standards. Additionally, all the results showed that this farm had not a management of brood stocks
