Abstract

Pterygoplichthys pardalis is a Loricariidae species commonly found in extremely polluted environments such as the Ciliwung River. Previous research showed that the Ciliwung River waters contain heavy metals, such as Cd, Hg, and Pb originating from industrial, agricultural, and household wastes. The heavy metal content has been detected in the flesh, organs, and bones of P. pardalis. This exceeds the maximum limit value set by the Drug and Food Control Agency. The main reasons to conduct this research were based on the fact that there was no prior information or research regarding the survivability of P. pardalis in the Ciliwung River. Hence, this research aimed to determine the survivability of P. pardalis based on the threshold concentrations of heavy metal compounds (Cd, Hg, and Pb) causing lethal effects on P. pardalis. The preliminary and acute toxicity, mortality percentage, and bioaccumulation of Cd, Hg, and Pb in the body of P. pardalis were also determined. The results showed that P. pardalis have a higher survivability in toxic freshwater environment such as Ciliwung River.
