The contamination of aquatic environments with heavy metals poses a serious threat to fish, potentially leading diseases or even death. Therefore, there is an urgent need for studies investigate the adaptability fish in metal-contaminated environments. Several have explored suckermouth catfish (P. pardalis) survive contaminated Ciliwung River. findings obtained showed that presence intestinal bacteria helped these overcome their intestines, thereby enabling survive. Analysis using Next Generation Sequencing (NGS) technology has succeeded identifying diversity P. pardalis living River, which Cd (0.3-1.6 ppm water & 0.9-1.6 sediment), Hg (0.6-2 0.6-1.8 and Pb (59.9-73.8 26.1-58.6 sediment). Diversity index was relatively high, but it had negative correlation contaminants. Actinobacteria, Firmicutes, Proteobacteria were abundant intestines from upstream downstream river, overall abundance range 15-48%. Furthermore, Mycobacterium along 6 other genera identified as core bacteria. bacterial communities all samples affected survival metals-contaminated rivers. fish's live this harsh environment indicated potential be utilized bioremediator river sediments.
