Interpretive Summary:

Technical Abstract: This article, Part 2 of a two-part story, includes highlights from the second day of the 2017 Aquaculture Innovation Workshop (AIW), which was organized by The Conservation Fund Freshwater Institute and held in Vancouver, British Columbia, November 29-30, 2017. Part 2 includes brief summaries of presentations by ten researchers who have focused efforts on improving our understanding of salmonid production in land-based and floating closed-containment systems. This article also includes a summary of a presentation that described progress made in developing a non-GMO approach for creating sterile fish, as well as summaries of two presentations that discussed innovations in fish feed. The final summary is of three presentations from industry suppliers who are challenging the status quo with innovations in RAS design and waste management. The article concludes with a discussion of how this series of nine AIWs has focused dialogue on the biological, technical, economic, and marketing opportunities and challenges surrounding salmonid production in closed-containment systems, but especially in land-based RAS. The research and development that has been presented at nine AIWs has provided essential support to the new producers, system suppliers, and consultants that work with RAS technologies, which in turn has helped to improve both the biological and technical reliability of these production systems while reducing risk.
