To induce synchronized maturation of mandarin fish, Siniperca scherzeri by controlling photoperiod and water temperature, experimental fishes were maintained in filtered recirculating tanks and exposed to three experimental condition, control, 23℃-16L8D. Mean gonadosomatic index (GSI) of the fishes held at 23℃-16L8D was much highest 10.85 than the GSI of the control, 1.88. For sexual maturation of mandarin fish, photoperiod was believed to be a prime factor and water temperature was a compensative factor.
