Environmental DNA, Volume 5, Issue 6, Page 1589-1607, November 2023., 2023 We assessed the performance of 22 DNA metabarcoding primer sets for detecting 103 species of marine and freshwater bony fishes, elasmobranchs, cephalopods, and crustaceans. We find that a portfolio of four markers targeting 12S, 16S, and multiple regions of COI identifies all reference taxa to family and nearly 60% to species.
