Farley et al.: Early marine growth in relation to marine-stage survival rates for Oncorhynchus nerka 



129 



population (Crozier and Kennedy, 1999). We suggest 

 that annual variability in the size of sockeye salmon 

 may be related to summer sea surface temperatures 

 along the eastern Bering Sea shelf temperatures that 

 appear to influence the spatial distribution and early 

 marine migration pathways of this species. 



Acknowledgments 



P. Hagen, formally with the Alaska Department of Fish 

 and Game in Juneau. Alaska, was instrumental in aging 

 and creating digital pictures of juvenile sockeye salmon 

 scales. We gratefully appreciate the help of the captains 

 (M. Cavanaugh and S. Brandstitter) and the crew of the 

 FV Sea Storm and captain C. Bronson and the crew of 

 the FV Great Pacific for their fine efforts and technical 

 assistance in all aspects of the field surveys. We thank 

 A. Wertheimer, G. Kruse, and three anonymous review- 

 ers for suggestions during this study and comments on 

 the manuscript.
