Technical Report 17

Preface:
The International Year of the Salmon (IYS; https://yearofthesalmon.org) is an international framework for collaborative outreach and research, and seeks to increase understanding and raise awareness of the challenges facing salmon and the measures to support their conservation and restoration against increasing environmental variability. The overarching theme of the IYS is “Salmon and People in
a Changing World,” and the proposed research themes are (1) status of salmon; (2) salmon in a changing salmosphere; (3) new frontiers; (4) human dimension; and (5) information systems. These five research themes are integrated into the current NPAFC Science Plan (2016–2022), whose goal is to understand variations in Pacific salmon production in a changing climate (https://npafc.org/science-plan/). The North Pacific Anadromous Fish Commission (NPAFC), with support by several partners—Fisheries Agency of Japan, Hokkaido Research Organization, Hokkaido Salmon Propagation Association, Japan Fisheries Research and Education Agency, Japan Salmon and Trout Resources Enhancement Association, North Pacific Marine Science Organization (PICES), and Tohoku Ecosystem-Associated Marine Sciences (TEAM)—hosted the Third NPAFC-IYS Virtual Workshop on “Linkages between Pacific Salmon Production and Environmental Changes” on May 25–27, 2021 (PST).

About 300 salmon experts and scientists from around the world registered for the virtual workshop. Not only were there 29 pre-recorded presentations and 32 e-posters, but also 13 keynote and 15 oral presentations. Summary and discussions also took place during three days of live sessions addressing the following topics (and sub-theme) related to the IYS research themes:

• • Salmon production in changing environments (status and trends of key salmon populations and their environments; effects of freshwater habitats changes on salmon production; survival mechanism of juvenile salmon in changing ocean environments; winter ocean ecology and survival of Pacific salmon; linkages between salmon production and climate/ocean changes)
  • New technologies/integrated information systems for salmon research and management (new technologies; integrated information and management systems)
  • (Special Session) Resilience for salmon and people: lesson from the Great East Japan Earthquake in 2011 (restoration of ecosystems and human society in the coastal zone systems; research for retrieval
    and sustainable management of salmon populations; risk management and sustainability for the coastal zone systems and salmon production)

The Workshop Science Committee consisted of Jun Aoyama (International Coastal Research Center, Atmosphere and Ocean Research Institute, Univ. Tokyo, Japan), Ed Farley, Jr. (Auke Bay Laboratories, NMFS, USA), Jim Irvine (Pacific Biological Station, DFO, Canada), Ju Kyoung Kim (Aquatic Living Resources Center, FIRA, Korea), Svetlana Naydenko (Pacific Branch of VNIRO (TINRO), Russia), Mark
Saunders (IYS North Pacific Steering Committee, Canada), Shigehiko Urawa (Chairperson; Fisheries Resources Institute, FRA, Japan), and Jeongseok Park (NPAFC Secretariat, Canada).

On behalf of the Workshop Science Committee, we thank all presenters and participants for sharing information and addressing the topics related to the IYS research themes at the workshop and for submitting materials for this volume. We also thank Aidan Schubert (IYS Coordinator) for facilitating the live sessions of the workshop. Live and pre-recorded oral and poster presentations given at the workshop are also available for educational purposes at https://npafc.org/workshop-presentations-2021.

Technical Report No.17 is a compilation of extended abstracts submitted by workshop presenters. Material in this report has not been peer-reviewed and does not necessarily reflect the views of NPAFC member countries, or authors’ agencies. I appreciate William Stanbury (NPAFC Web/Publication Manager) and MacKenzie Kermoade (2021 NPAFC Intern) for their help in editing the extended abstracts. Abstracts have been edited for clarity and publication purposes.
