Abstract
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. The data obtained are very useful for the sustainable
management of P grootii resources.
