Evaluation of an Environmental DNA Method as a Potential Tool for Monitoring Salmonid Fishes in the Wild

Abstract Excerpt:
There are a variety of migratory fish species in the North Pacific, including Pacific salmonids (Oncorhynchus spp.). While there is no doubt that they play an important role in the ecosystem and commercial fisheries, it is difficult to obtain a comprehensive understanding of their migration routes and spatio-temporal distribution precisely, partly due to the huge efforts and costs required for collecting such data with conventional research tools.
