UTTER ET AL.: STOCK COMPOSITION OF 1983 CHINOOK SALMON 



sistent need to understand the composition of stock 

 mixtures of salmonids (and other structured groups) 

 better. The obvious management potential of such 

 uses is matched by increased understanding of popu- 

 lation structuring and of migratory behavior that 

 will emerge as information accumulates. 



ACKNOWLEDGMENTS 



This study could not have been carried out with- 

 out the assistance in all phases of sampling of 

 Richard Lincoln, Mark Miller, and Patrick Pattillo 

 of Washington Department of Fisheries.
