Background:
Pacific salmon face many challenges and uncertainties associated with environmental variability,
including climate change. It is more important than ever that we promote new international cooperative
research that provides better scientific information on the ecological mechanisms regulating production ofanadromous populations and climate impacts in North Pacific marine ecosystems.
The North Pacific Anadromous Fish Commission (NPAFC) and North Atlantic Salmon Conservation
Organization (NASCO) are leading a major initiative entitled “International Year of the Salmon (IYS).”
IYS provides an international framework for collaborative outreach and research. These efforts will raise

2
awareness of the challenges salmon face for improved stewardship during this period of increased
environmental variability.
The IYS overarching theme is “Salmon and People in a Changing World” with six subthemes: (1) Statusof Salmon; (2) Salmon in a Changing Salmosphere; (3) New Frontiers; (4) Human Dimension; (5)Information Systems; and (6) Outreach and Communication. IYS is stimulating investment in research
expected to provide a legacy of knowledge, data/information systems and tools, and help train a newgeneration of scientists better equipped to provide timely advice to improve stewardship of salmon. In
addition, the IYS program is connected to the 2016–2022 NPAFC Science Plan, whose research themesare (1) Status of Pacific salmon and steelhead trout; (2) Pacific salmon and steelhead trout in a changing
North Pacific Ocean; (3) New technologies; (4) Management systems; and (5) Integrated information
systems. Annual progress for each research theme is reviewed at a series of NPAFC-IYS workshops
including the present one.
Workshop Objectives: Improve knowledge of the migration, growth and survival of salmon and their environments;
 Increase understanding of the causes of variations in salmon production in changing environments;
 Anticipate future changes in salmon ecosystems and resulting changes in the distribution, survival,
and abundance of salmon;
 Discuss the application of new and developing technologies and analytical methods to research andmanage salmon;
 Demonstrate integrated information/data management systems to support research, sustainable
management, and understanding for the conservation of salmon; and Describe policies designed to ensure the resilience of salmon and people in changing environments.
Topic Sessions:
Topic 1. Salmon production in changing environments
Moderators: Ed Farley* (SC & TCG-1), Jim Irvine* (SC), Ju Kyoung Kim (SC & TCG-1), Svetlana
Naydenko (SC), and Hiromichi Ueno (TCG-1) *session co-leader
The response of Pacific salmon to climate-driven environmental changes is variable and differs by species,
populations, life stages, geographical locations, and/or seasonal timing. Variation in the early marine
survival of salmon has been hypothesized to have a major role in determining brood year strength.
However, there has been limited evidence to support this hypothesis. We need to understand the causes
and mechanisms of mortalities at each stage of the salmon life cycle. This is necessary to understand andpredict the responses of salmon to climate change and other factors, and to prepare for future scenarios. In
the ocean, for example, climate change may result in significant variability and overall declines in the
carrying capacity and usable habitat of Pacific salmon in the North Pacific Ocean, potentially leading to
expanded use of the Arctic Ocean. An improved understanding of linkages between environmental
changes and salmon production will help to enhance our predictions of changes to the distribution,
abundance, and vulnerability of salmon populations to climate change for sustainable resource
management.
1-1. Status and trends of key salmon populations and their environments
Time series of regional salmon production and biological and physical characteristics of key salmon
populations and their ocean habitat provide broad scale perspectives necessary to examine theunderpinnings of ocean salmon production and marine ecosystem conditions. The purpose of this subsession is to understand the current status and trends of Pacific salmon production and their habitat.
(Keywords: key salmon populations, trend, spawning escapement, catch, survival rate, body size,
fecundity, smolt production, distribution, abundance, habitat conditions, and others)
1-2. Effects of freshwater habitat changes on salmon production
Physical changes to freshwater ecosystems resulting from human impacts and climate change will degradeand diminish available habitat, reduce reproductive success, and impact migration of salmon. Increasingwater temperatures may cause direct and indirect impacts on salmon including physiological stress,

3
increased depletion of energy reserves, increased susceptibility and exposure to diseases, and disruptions
to breeding efforts. The sub-session will: (1) review the impact of freshwater habitat changes on salmon
production; and (2) evaluate effectiveness of habitat restoration programs to enhance resilience of salmon.
(Keywords: freshwater salmon habitat, human impact, climate change, reproductive success, growth,migration, physiological stress, diseases, mortality, restoration, resilience, and others)
1-3. Survival mechanisms of juvenile salmon in changing ocean environments
There is growing recognition that size-dependent mortality of juveniles within the first ocean year
regulates Pacific salmon production, which also suggests that environmental influences are greater in thefirst ocean year than later. The sub-session aims to increase our understanding of survival mechanisms ofjuvenile salmon and their responses to changing environments including SST, salinity, currents, prey
abundance, inter- and intra-specific competition, and predators.
(Keywords: juvenile salmon, marine survival mechanism, ocean entry, feeding, growth, migration, SST,
salinity, currents, prey, competition, predators, and others)
1-4. Winter ocean ecology and survival of Pacific salmon
One hypothesis is that winter is a critical period for Pacific salmon in the ocean, but winter surveys havebeen limited, and have yet to fully test this hypothesis. Key gaps in our understanding of winter ocean
ecology and survival of salmon include: (1) winter ocean distribution and abundance by species andpopulation, (2) ocean habitat environments including prey abundance, (3) key factors influencing winterdistribution and abundance, (4) effects of changing winter environments on feeding, growth andmetabolism, and (5) mechanisms determining winter survival. The international Gulf of Alaska expedition
conducted in 2019 was the first comprehensive survey of Pacific salmon in winter/spring in the North
Pacific Ocean in several decades. Results from this expedition will be presented to fill gaps in our
knowledge of winter salmon in the ocean. Other presentations on winter salmon ecology and survival are
welcome.
(Keywords: winter salmon, spatial and temporal dynamics of habitat conditions, stock-specificdistribution and abundance, preys, food web, feeding, metabolism, growth, trophic and health conditions,
survival mechanisms, and others)
1-5. Linkages between salmon production and climate/ocean changes
The future of salmon is uncertain. Climate change may increase variability in the carrying capacity andusable habitat (distribution) of salmon in the ocean. Improved understanding of linkages between
environmental changes and salmon production will help anticipate the economic consequences of thesechanges. The objectives of the sub-session are to: (1) understand and quantify the effects of environmental
variability and anthropogenic factors affecting salmon distribution and abundance; (2) develop methods topredict future changes in salmon distribution and abundance with climate change, and (3) predict
implications of climate/ocean environmental changes on salmon management.
(Keywords: climate impact, distribution, abundance, carrying capacity, linkage between salmon, climate
and ocean changes, forecast models, energy budget models, biophysical models, and others)
1-6. Summary and discussion

Topic 2. New technologies/integrated information systems for salmon research and management
Moderators: Kazushi Miyashita (TCG-3), Dion Oxman (TCG-3), Shunpei Sato (TCG-3), and Mark
Saunders* (SC) *session leader
With recent advancements in technology, data processing, and analytical methods, new tools are available
to better study and manage salmon. The IYS aims to further advance the development of new andemerging technologies and analytical methods that are immediately available for salmon research andmanagement. In addition, the IYS seeks to create open-access information systems for salmon research
and management, and to develop management systems to aid the sustainable conservation of salmon in achanging climate.

42-1. New technologies
Novel stock and fish identification methods including molecular analyses, genomics, environmental DNA(eDNA), hatchery mass marking, intelligent tags, and remote sensing, continue to be developed, and thesetools are integral to the formulation of effective models predicting the distribution and abundance ofsalmon populations. This sub-session will emphasize: (1) eDNA as an indicator of salmon distribution andabundance in aquatic ecosystems; (2) use of existing scale and otolith collections to determine ocean
distribution of salmon (otolith microchemistry) and analyses of growth patterns to examine size-dependentmortality hypotheses; (3) potential for the application of real-time GSI and detection of pathogens at sea;and (4) intelligent data logger and tacking methods to determine migration behavior and survival.
(Keywords: genomics, environmental DNA, molecular identification, mass marking, intelligent tags,
salmon observation systems, remote sensing, microchemistry, and others)
2-2. Integrated information and management systems
The IYS seeks to develop integrated information/data management systems using new and existing data
sets to increase the resiliency of salmon and people in a changing world, to support research andmanagement, and to increase public understanding of the role salmon have in ocean ecosystems. For thesustainable conservation of uncertain salmon populations, we need to develop integrated management
systems including ecosystem-based management, improved management strategies for harvest andescapements, long-term sustainable conservation of genetic units and diversity, restoration and protectionof marine and freshwater habitat, control of diseases and pollution, resilient salmon enhancement/hatchery
technologies, and application of indigenous and local/traditional knowledge.
(Keywords: integrated information system, management strategy of harvest and escapements, genetic
conservation, habitat restoration and protection, control of diseases and pollution, renovation ofenhancement/hatchery technologies, indigenous and local/traditional knowledges and others)
2-3. Summary and discussion
Topic 3 (Special Session). Resilience for salmon and people: lessons from the Great East Japan
Earthquake in 2011
Moderators: Jun Aoyama* (SC & TCG-2), Masahide Kaeriyama (TCG-1), and Shigehiko Urawa (SC &TCG-4) *session leader
The IYS is seeking to ensure that salmon and people are resilient to changing environments. The Great
East Japan Earthquake (GEJE) on March 11, 2011 was devastating for salmon and people. It created a
massive tsunami that killed more than 18,000 people and gravely damaged the coastal zone systems,
including salmon habitats, hatcheries and fishery facilities along the Pacific coast of northern Honshu.
Tohoku Ecosystem-Associated Marine Sciences (TEAMS) was launched in January 2012 as a decadelong project to clarify the impacts of the GEJE and the restoration process of marine ecosystems for thereconstruction of local subsistence and fishery industries. In conjunction with TEAMS, this special sessionis planned to review the impact of the GEJE on salmon, people and coastal ecosystems, and the recovery
processes for human security and risk management. Lessons learned from this project should contribute toenhancing the resilience of salmon and people in the face of future challenges elsewhere.
3-1. Restoration of ecosystems and human society in the coastal zone systems
Salmon have a long historical association with local people in northern Honshu, being a vital resource forvarious aspects such as food, economy, recreation, culture and education. The GEJE damaged coastal
ecosystems as well as human society connecting with salmon and other marine resources. Long-termmonitoring surveys have been initiated by TEAMS to assess changes in the marine ecosystems and humansociety affected by the GEJE. This sub-session introduces the outcomes of TEAMS to understand theprocess and mechanism of restoration in coastal ecosystems and the recovery of human society.
(Keywords: coastal ecosystem, human society, impact of earthquake/tsunami, restoration, and others)

53-2. Research for retrieval and sustainable management of salmon populations
Chum salmon are an important fish resource in northern Japan, and most populations have been
maintained by hatchery releases. This sub-session introduces research results of TEAMS in order to: (1)assess the impact of the GEJE and other factors on the behavior, survival and returns of chum salmon; and(2) review the procedure of recovery and sustainable management for chum salmon populations.
(Keywords: chum salmon, survival, impact of earthquake/tsunami, recovery procedure, sustainable
management, and others)
3-3. Risk management and sustainability for the coastal zone systems and salmon production
As a result of the huge tsunami, millions of tonnes of marine debris including live organisms were widelydispersed into the Pacific Ocean. Radioactive materials were also released into freshwater and marine
environments from the damaged Fukushima Daiichi nuclear power plant. In addition, non-native coho
salmon escaped from broken net-pens in coastal waters. The sub-session intends to recommend: (1) risk
management approaches including the adaptive management, precautionary principle and feedback
control between monitoring and modeling; and (2) sustainable processes for the coastal zone systems andsalmon production from catastrophic disaster, such as the GEJE and global warming effects.
(Keywords: risk management, adaptive management, monitoring, modeling, sustainable process, coastalzone system, salmon production, and others)
3-4. Summary and discussion: overview of lessons learned for future challenges

Title: Late ocean entry timing provides resilience to populations of Chinook and sockeye salmon in the
Fraser River
Authors: Richard J. Beamish*, Ruston Sweeting, and Chrys Neville
Pacific Biological Station, Fisheries and Oceans Canada, 3190 Hammond Bay Rd., Nanaimo, B.C., V9T

Abstract: Most sockeye salmon from the Fraser River enter the Strait of Georgia by early May and most
Chinook salmon by mid May. There are populations of Chinook salmon from the South Thompson River
area and one population of sockeye salmon from the Harrison River that enter the Strait of Georgia almost
two months later. The productivity of these species with a late ocean entry life history strategy has been
exceptional in recent years. The reasons for the recent improved productivity of the late ocean-entry life
history type are not known, but the success identifies the importance of a temporal spread in ocean entry
timing of the aggregate of populations. The recent success also reminds us that ocean entry timing of theaggregate of populations has evolved to be able to adapt to long-term changes in the timing of prey
populations in the early marine period.
