Associations between bioindicators of contaminant exposure, atresia severity, and nutritional factors in English sole and egg 
weight, fecundity, and relative fecundity as determined through multiple regression, while adjusting for effects of fish size, GSI, 
and sampling time. For each independent variable, t-value, P-value, and sample number (n) are shown. The sign of the f-value 
indicates the direction of the association (positive or negative). Statistically significant associations (P<0.05) are indicated in bold.

are needed to confirm that Duwamish and Sinclair 
Inlet fish do in fact have a higher growth rate or 
longer period of growth than fish from the other sam- 
pling areas, the present results suggest that intersite 
differences in growth rate may have a significant 
effect on age-specific egg production in Puget Sound 
English sole. This problem deserves further investi- 
gation because of its potential impact on sole popu- 
lation dynamics. 
Another notable finding was the tendency of En- 
glish sole from the Duwamish Waterway to produce 
more and smaller eggs than fish of comparable size
