DNA analysis of seawater detects 80% of fish species in just one day
A Japanese research group has used a new technology that identifies multiple fish species populating local areas by analyzing DNA samples from seawater, and proved that this method is accurate and more effective than visual observation.

These findings show that even in areas with many different fish species, eDNA metabarcoding enables researchers to survey fish in multiple areas during a short time period. This method has potential applications for monitoring the invasion of foreign species across large areas, surveys of expanding fish distribution, and use in hard to access areas such as the deep sea, subterranean lakes, dangerous polluted waters, and protected areas where collecting specimens is prohibited. The findings were published in Scientific Reports.
