The purpose of this study to find the optimum concentration of java long pepper extract on spermatozoa motility of mustika common carp. Java long pepper extract was injected by intramuscularly on the first of week with the concentration are 0.9ml kg^-1, 1.8ml kg^-1, and 3.6ml kg^-1 of body weight, respectively. SnGrH (ovaprim) with the concentration is 0.3mlkg^-1 bodyweight was administered as a positive control, whereas 0.3 ml of sodium solution was applied as a negative one.
