Özet

In this study, the fatty acid compositions of semen seminal plasma in rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta fario) were analyzed in fresh semen by gas chromatography (GC) and investigated the relationships with the sperm cell velocities. According to our results, total levels of saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA) for Salmo trutta fario occurred in higher quantities than Oncorhynchus mykiss but the quantities of total polyunsaturated fatty acids (PUFA) were less. Palmitic and stearic acid for SFA, oleic and nervonic acids for MUFA and linolenic, arachidonic, eicosapentaenoic and docosahexaenoic acids for PUFA of semen seminal plasma were main. Semen volume and the levels of SFA (myristic, palmitic and margaric acid), MUFA (palmitoleic, ginkgolic, oleic and nervonic acid) and PUFA (linoleic, gama-linolenic and eicosadienoic acid) were significantly different (p<0.05) between both species. Especially, the levels of eicosapentaenoic (EPA) and docosahexaenoic (DHA) determined no significant different (p>0.05). Additionally, we found negative correlation between the straight line velocity (VSL) and pentadecanoic acid (r =-0.78, p<0.05), stearic acid (r =-0.76, p<0.05) and nervonic acid (r =-0.89, p<0.01) for rainbow trout, while there was negative correlation (r =-0.96, p<0.05) between angular path velocity (VAP) and EPA for brown trout. Finally, it can be concluded with these results that the fatty acids of sperm seminal plasma affect the velocities of sperm cells and they would also improve semen quality and fertilization protocols.
