The maximum value that can be exploited was 223 kg and the utilization rate was 7%.  The water quality parameter shown that temperature 27-29 °C, current speed 25.9-28.5 cm/s, and depth 3.55-3.87 m. Data on water quality parameters indicate that water quality in the Indragiri River is able to support the life of   B. schawanefeldii . Keywords : Leslie method, Maximum value, Utilization rate, Exploitation rate
