Table 2. Primers used for targeting and amplification of the COI region. Six primers were designed from this study and from Fisch-Muller et al. (2018) to obtain longer sequences of >800 bp. Other primers are from Ward, Zemlak, Innes, Last, & Hebert (2005) and amplify a region of approximately 650 bp. Sil = Siluriformes, Char = Characiformes.
