tion of these catches (Teel et al., 2003) and the release 

 weights (Appendix Table 1). Similarly, the back-calculated 

 weight at ocean entry in June in the GLOBEC area (45.5 g) 

 was slightly higher than the expected average weight at 

 hatchery release (about 41 gl based on the stock compo- 

 sition (Table 5) and the average release weights. These 

 fairly small differences between back-calculated size at 

 ocean entry and average size at release could be due to 

 growth during downstream migration, selectively higher 



mortality of small smolts, or a bias in the back-calculation 

 procedure. 



However, the average back-calculated weights at time of 

 ocean entry offish caught in August in the GLOBEC study 

 area (60-69 g) were over two standard deviations above the 

 average weights of hatchery fish released from the Oregon 

 coast or northern California — the main contributors to this 

 catch (Appendix Table 1). These were obviously atypical 

 coho salmon, and the very high proportion of jacks (preco-
