• eDNA-based assays successfully identified the presence of Oreochromis niloticus in various aquatic habitats, demonstrating high sensitivity compared to traditional survey methods.• The study highlights the effectiveness of eDNA in detecting low-density populations, enabling early intervention before the species establishes a strong foothold.• The study provides evidence of O. niloticus expansion into new ecosystems, raising concerns about potential ecological disruptions and native species competition.• eDNA monitoring offers a non-invasive, cost-effective approach for tracking invasive species, aiding in targeted control strategies and biodiversity conservation efforts.• This research contributes to refining eDNA-based ecological assessments by optimizing sampling protocols, degradation analysis, and data interpretation techniques.
