was 20^m for both transects, did not significantly 

 differ. 



Despite the differences among transects, the over- 

 all trend in Chesapeake fish was a nadir in Sr/Ca ratio 

 at or shortly after anntili that coincided with spring 



spawning runs (Merriman 1941, Robinson 1960). 

 This trend occurred only in fish >4 years old. There 

 was a significant increase in the overall Sr/Ca ratio 

 in fish >5 years for two of three Chesapeake fish 

 (Table 4).
