Abstract
Length-weight relationships, condition factors, and environmental parameters are important parts of fisheries management. The freshwater fish species Puntigrus tetrazona is endemic to Indonesia. The objective of this study was to determine the length-weight relationship, condition factors, and environmental parameters of P. tetrazona from the Kelekar River in South Sumatra. A total of 121 P. tetrazona were used in this study. The results showed that the length-weight relationship of P. tetrazona was negative allometric, with the regression equation W = 0.0656 x L1.9002 (R2 =0.5603). The P. tetrazona population was in good condition, as indicated by a condition factor value of 1.00. Environmental parameters including water temperature, pH, dissolved oxygen, electrical conductivity and oxidation reduction potential are suitable for the life of P. tetrazona. The findings of this study will be of significant value in informing the management of P. tetrazona resources.
