Process of DNA Metabarcoding

The image shows the process of DNA Metabarcoding from DNA strands in a water sample, extraction of DNA from the sample, PCR amplification of all fish species DNA, and lastly the identification of all fish species DNA found in the sample.

Samples are collected and sent to the lab. DNA is extracted from the sample similar to qPCR. The lab uses PCR to amplify all the fish DNA found in the sample. Amplified DNA is then sequenced and compared to a reference sequence database to identify all the fish species that had amplified DNA in that sample.
