Ocean Ecology of Salmon in Western North America: Regional ComparisonsModerator: Churchill Grimes Date: Monday, September 12 and Tuesday, September 13, 2005 Understanding the interaction between Pacific salmon and their environment is critical for salmon management. Because salmon are anadromous, they are affected by many factors in both freshwater and the ocean. However, recent studies suggest that salmon production is strongly influenced by events in the ocean. In particular, changes in marine survival appear to be related to sudden shifts in climate and ocean conditions on varying time scales, e.g., El Niño on decadal and PDO on multi-decadal time scales. The mechanisms linking salmon production and climate are still poorly understood, and there appear to be regional differences in how ocean climate affects production. Knowledge of ocean conditions and how they affect the distribution, migration, growth and survival of Pacific salmon at the appropriate spatial scale is required to predict how salmon populations will respond to forecasted ocean climate changes, and for incorporation in population models allowing more effective management. The objective of this session is to bring scientists together to review recent advances in our understanding of the ecology of salmon in the North Pacific and Bering Sea and the influence of ocean climate on the abundance of Pacific salmon stocks. Presentations will focus in particular on regional comparisons. We intend that the symposium will result in a published volume, probably in the AFS Symposium series, and we have a tentative commitment from AFS editors for special volume.
