Key Findings
- In a Japanese study, nuclear genes in eDNA/eRNA allowed better detection of fish species than mitochondrial genes
- eRNA showed more variability than eDNA, making it less reliable for estimating fish numbers
- These insights can improve aquatic species monitoring and conservation efforts
