Environmental DNA and its applications to Fisheries and Oceans Canada : national needs and priorities / by Shauna M. Baillie, Colin McGowan, Shannan May-McNally, Rosalind Leggatt, Ben J.G. Sutherland,... : Fs97-6/3329E-PDF

"Environmental DNA (eDNA) detection is a revolutionary approach that aims to determine the presence of organisms, and other population parameters, by extracting the genetic material released from living and dead organisms in environmental samples, such as water. The rapid development of tools and technologies associated with eDNA has generated an unprecedented ability to detect species for biosecurity, biosurveillance, aquaculture, commercial fishery, and aquatic conservation management activities around the globe. In this report, we discuss the growing use of eDNA in Canada and its applications to DFO Programs related to at-risk and aquatic invasive species, fisheries management, sustainable aquaculture, aquatic animal health, and sustainable aquatic ecosystems. We highlight the challenges and technical considerations inherent to the use and interpretation of eDNA, and provide recommendations towards development of best practices and minimum reporting standards. Also, we review the fast-advancing field methods and DNA sequencing technologies used to study eDNA, where we see the most potential for growth within DFO. Altogether, this report describes the beginning of a national dialogue on research priorities and other science needs essential to providing the best possible advice on the use of eDNA for management decisions regarding the protection Canada’s aquatic resources and environments"--Abstract, page xiii.
