1st Announcement and Call for Abstracts (Deadline for abstract submission is November 16, 2012)

The North Pacific Anadromous Fish Commission will host an international workshop on “Migration and Survival Mechanisms of Juvenile Salmon and Steelhead in Ocean Ecosystems” to be held on April 25-26, 2013, at the Sheraton Princess Kaiulani Hotel, Honolulu, HI, USA.
In recognition of the importance of understanding juvenile salmonid production in ocean environments, NPAFC has organized two previous workshops on the subject of juvenile salmonids in marine habitats. In 2000, the NPAFC organized a “Workshop on Factors Affecting Production of Juvenile Salmon” in Tokyo, Japan, and presentations were summarized in NPAFC Technical Report 2 and national review papers were published in NPAFC Bulletin No. 3. In 2006, the NPAFC convened the “Second International Workshop on Factors Affecting Production of Juvenile Salmon” in Sapporo, Japan. Presentations were summarized in NPAFC Technical Report 7. The previous workshops have suggested the initial period after juvenile salmon migrate to sea and the following first winter are the most critical phase with respect to ocean survival of anadromous populations. Observations have shown there is considerable inter-annual variation in abundance, growth, and survival rates of juvenile salmon in the ocean. These variations are related to climate-induced changes in habitats that operate at regional and local scales. These processes are monitored annually in the coastal and offshore waters of Asia and North America. Using long-term monitoring data, scientists have begun developing models to forecast commercial harvest. Study of the migration and survival mechanisms of juvenile salmon is a research component of the 2011-2015 Science Plan, “Forecast of Pacific salmon production in the ocean ecosystems under changing climate” (NPAFC Doc. 1255). During the seven years between the second juvenile salmonid workshop in 2006 and the upcoming workshop in 2013, significant new research results have become available, so researchers will have the opportunity to share and review current information on migration and survival mechanisms of juvenile salmon and steelhead in ocean ecosystems.
Objectives and Topic Sessions
Workshop objectives:
Presenters are encouraged to address one of the following workshop objectives within the framework of their selected topic session. Workshop objectives include the following:
Workshop topic sessions:
The workshop includes the following topic sessions pertaining to juvenile salmon and steelhead in ocean ecosystems. Please identify the topic session for which the abstract is submitted (topics 1through 7 listed below).
  1. Seasonal distribution and migration route/timing
  2. Hydrological characteristics, primary production, and prey resources in marine habitats
  3. Trophic linkages, growth rates, and predation rates
  4. Ecological interactions among species and populations
  5. Survival rate and survival mechanisms
  6. Population size and carrying capacity
  7. Survival and salmonid ecology during the first winter at sea
Oral and Poster Presentations
The workshop will be conducted in English. Sessions will comprise contributed presentations, which will be selected for oral or poster presentation. Oral presentations are 15 minutes followed by 3 minutes of discussion for a total of 18 minutes. Presenters will be held strictly to their time slots, so please plan the presentation accordingly. Posters will be available for viewing throughout the duration of the workshop.
  • Abstracts for oral and poster presentations must be received by November 16, 2012 at the NPAFC Secretariat by e-mail (
  • Abstracts must be prepared according to the guidelines and sample format shown below.
  • The Organizing Committee will select abstracts by the middle of December 2012, and authors will be notified of the results by the NPAFC Secretariat.
  • Presenters who had their abstracts selected will receive guidelines for their oral or poster presentations and a formatting guide for extended abstracts from the NPAFC Secretariat. (See Workshop Proceedings below).
