characteristics tend to be somewhat lower in 

 the Alsek and Anchor Rivers than in the Copper 

 and Taku Rivers, the overlap is considerable, 

 and neither characteristic is clearly diagnostic 

 of fish from any of the rivers. 



CONCLUSIONS 



Yearly variations in fresh-water growth of 

 the scales of chinook salmon make it necessary 

 to limit comparisons of first-year scale growth 

 to fish of the same brood year. But even when 

 fish of the same brood year were compared, 

 differences in numbers of circuli and lengths 

 of radii were not sufficient for reliable classi- 

 fication of fish according to river of origin in 

 the four stocks studied.
