The Effects of Ions Ratio on Semen Biological Characteristics in Kutum {Rutilus frisii kutum)

The effects of Na+, K+, Ca2+, Mg+2, ratios on semen biological characteristics in 21 male samples of kutum {Rutilus frisii kutum) were investigated during spawning migration. All ratios were investigation three treratments Na+to K+ (1: 3-8 Mmol, 2:8-13 Mmol and 3: 13-18 Mmol); Na+ to Ca2+ (1: 100-400 Mmol, 2: 400-700 Mmol and 3: 700-1000 Mmol); Na+ to Mg2+(1: 80-120 Mmol, 2: 120-160 Mmol and 3: 160-200 Mmol); K+ to Ca2+ (1: 10-40 Mmol, 2: 40-70 Mmol and 3: 70-100 Mmol); K+ to Mg2+(l: 3-19 Mmol, 2: 19-35 Mmol and 3: 35-51 Mmol); and Ca2+ to Mg2+(1: 0.1- 0.3 Mmol, 2: 0.3- 0.6 Mmol and 3:0.6- 0.9 Mmol). It was found increase in Na+to Ca2+ ratio resulted in significant (p<0.05) decrease of sperm duration and spermatocrit. Na+ to Mg2+ ratio effected on Na+ and total protein, K+ to Ca2+ ratio effected on Ca2+ and total protein also K+to Mg24" ratio effected on glucose and Mg2+. With regard effect of ions ratio on this parameters, that are sperm quality parameters, so ions ratio with others parameters should be regarded for selection of suitable quality sperm.
