juvenile sockeye salmon in the trawl samples taken 

 during years 2000, 2001, and 2002. For instance, juve- 

 nile sockeye salmon contributing to the early marine 

 population during 2000 comprised age-2.0 fish from the 



1997 and age-1.0 fish from the 1998 brood-year escape- 

 ments, and these fish would have returned as adults 

 during 2002 and 2003. Relative marine-stage survival 

 rate (RS) was thus calculated as
