SURVEY OF EFFECTS OF DIFFERENT CONCENTRATIONS OF ELECTROLYTES AND PH ON CHARACTERIZATION OF SPERM MOTILITY IN WILD CARP (CYPRINUS CARPIO)

Effects of pH, Na, K, ci2+ and Mg2+ ions on characterization of sperm motility (duration of motility and percentage of motility) of wild carp (c. carpio) were investigated. After determination of optimum pH, its interaction effect with Na, K, Ca2+ and Mg2+ was studied. Maximum motility (duration of motility and percentage of motility) was observed at pH=8. 5. Effects of different treatments of Nacl on sperm motility was significantly different (P0. 05) while that of the Mgch was significantly different (P0. 05). In general, it is concluded that movement of spermatozoa of wild carp is influenced by high concentration of ions.
