    Comparison of some elements in sperm seminal plasma of rainbow trout (Oncorhynchus mykiss) and Brown trout (Salmo trutta fario)
    (Nobel Science and Research Center, 2015) Özgür M.E.; Yumuşakbaş H.; Dağli M.; Erdoğan S.
    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.

    Some quality parameters of surface water of Karasu River in upper part of Euphrates Basin, Turkey
    (2012) Özgür M.E.; Akbulut A.; Demirsoy A.
    Research in Euphrates basin in Turkey showed the following values: temperature, dissolved oxygen, pH, nitrite, nitrate, chlorine, sulfate, iron, copper, calcium, magnesium and silica in surface waters were monitored. Significant relationships among these parameters were observed at seasonal term. Some significant (p<0.05) differences were determined among the parameters (temperature, dissolved oxygen demand, nitrite, chlorine, sulfate, iron and copper) according to seasons. pH was not determined a significant (p>0.05) differences in all seasons. However, it was also significant (p<0.05) differences the results of nitrate at summer, calcium and magnesium at spring, silica at winter as other seasons. The data of chlorine, iron, and copper in Karasu River were measured high levels according to water quality standards of EPA.
