The Indonesian leafffish (Pristolepis grootii, Bleeker 1852) is one of the native Indonesian freshwater fish species. It’s have a high economic value. The habitat of the fish is rivers, lakes and swamps. The study of the length-weight relationship and environmental parameters an important and fundamental component of fisheries resource management. The purpose of this study was to analyze length-weight relationship of P. grootii and water quality of the fish habitat. A total of 164 samples were used in this study. The results showed that length-weight relationship of the P. grootii, the predictive model of the weight of the fish from the length of the fish is in the exponential form with the equation y = 0.0491x2.6363 (R2 = 0.9536: P < 0.01), with a coefficient of (a) 2.636 and a constant (b) of 0.049. The P. grootii weight gain was slower than the increase in length. Environmental parameters such as water temperature, dissolved oxygen, alkalinity, nitrate, and phospate are within acceptable limits. P. grootii are found in Kelekar river. The current study provided the first baseline data about length-weight relationship and environmental parameters of P grotii from the the Kelekar river, Ogan Ilir Regency, South Sumatra, Indonesia. Such data is valuable for establishing a monitoring and management system of these fish species.
