One way to produce seeds is by spawning. The main parameters observed in this study were fertilization rate, hatching rate and survival rate. The value of the fertilization rate in spawning is 70%. The hatching rate in spawning was 68% and survival rate for spawning was 47%. The water quality value obtained at the time of the study were pH 6.7-7.4, temperature 26.5-29.50C and DO 5.23-7.33 mg/l.
