Portable eDNA sequencing worked—but missed much of the known fish diversity
WHAT THE EVIDENCE SAYS
BentoLab and MinION equipment supported sampling-to-analysis outside a conventional laboratory within roughly five days. Seven samples returned 26 species after manual review of database misidentifications, compared with 51–65 reported by earlier local studies.
WHY IT MATTERS / OUR READ
Deployable molecular methods expand access but faster results cannot replace representative sampling and reference quality.
CAVEATS / UNCERTAINTY
Limited replication, primer selection, sequencing errors and no field blanks restrict accuracy claims; detection probability was not equivalent across studies.
