Method for recovering nucleic acids derived from aquatic organisms
By contacting habitat water with an adsorbent and filtering it through specific pore size filters, followed by ion exchange column extraction, the method recovers nucleic acids from aquatic organisms non-invasively, achieving higher-resolution genetic analysis.

AI Technical Summary
Existing methods for recovering nucleic acids from aquatic organisms are inadequate for obtaining high-resolution genetic information, such as distinguishing between subspecies and varieties, and require invasive sampling that damages the target organisms.
A method involving contacting habitat water with an adsorbent that adsorbs microorganisms, followed by filtration using a specific pore size filter, and subsequent nucleic acid extraction using an ion exchange column method to recover longer DNA strands without damaging the organisms.
Enables non-invasive recovery of nucleic acids with higher mapping rates and longer DNA strands, allowing for more accurate genetic analysis, including subspecies identification and genetic diversity analysis.
