NPAFC Science Plan

NPAFC Science Plan is a long-term plan for coopertaive scientific research. The present plan, which was adopted by the commission at its 2005 annual meeting is for the period of 2006-2010.


NPAFC Science Plan 2006-2010

Broad Scientific Questions

Overarching hypotheses that emerged from the results of scientific research under previous NPAFC science plans, as well as from research by other organizations and independent scientists, are that (1) anadromous stocks play an important role in North Pacific marine ecosystems, and (2) there is a close relation between climate and climate change and subsequent changes in marine productivity and survival of anadromous stocks in the ocean.

The Science Sub-Committee (SSC) identified two broad scientific questions relevant to the program goals of NPAFC that would further an ecosystem-based approach to conservation of North Pacific anadromous stocks, as well as contribute substantial new scientific information to the marine ecosystem research, fishery management, and conservation activities planned by relevant organizations:

  • What are the current status and trends in marine production of anadromous stocks; and how are these trends related to population structure (spatial and temporal) and diversity of anadromous stocks in marine ecosystems of the North Pacific?
  • How will climate and climate change affect anadromous stocks, ecologically related species, and their North Pacific marine ecosystems?
Over the past decade, there have been significant variations in the marine production of Asian and North American anadromous stocks that appear to be linked to climate change. There is a strong need for new international cooperative research that provides better scientific information on the status and trends in marine production of anadromous stocks, identifies the roles of anadromous stocks in North Pacific marine ecosystems, and examines the extent to which anadromous stocks, since they return to coastal regions, can be used as indicators of conditions in North Pacific marine ecosystems.

Variation in the time, frequency, and amplitude of climate events that affect the ocean production of marine fish seems to be increasing. This has led many experts to conclude that precision monitoring of abundance and biomass in the ocean may be the only reliable method for predicting changes in production of anadromous stocks. That each species of salmon follows a life history strategy in the ocean is probable. Cooperative research that identifies the common mechanisms will improve regional forecasting. In addition, the conceptual framework for the management of fish populations has expanded from relatively simple assessments of abundance and productivity to broader needs for information on population structure (spatial and temporal) and diversity.
