“…Numerous studies have applied molecular methods to natural water samples to estimate the abundance, species composition, and diversity of fish communities (Evans & Lamberti, 2017; Hansen, Bekkevold, Clausen, & Nielsen, 2018; Wilcox, Carim, et al, 2018). However, results are not always straightforward and current knowledge highlights both the potentials and limits of eDNA methods to quantify the abundance of fish populations (e.g., Capo, Spong, Norman, et al, 2019; Levi et al., 2019; Nevers et al., 2018; Wilcox et al., 2016; Wilcox, Young, et al, 2018; Yates, Fraser, & Derry, 2019).…”
