Fig. 2. Effects of dietary and waterborne Cu exposure conditions on whole body Cu concentration in actively growing rainbow trout. Values are means ± S.E.M., N=15 for weeks 0, 2 and 4, and N=9 for week 7 for each treatment. Diamonds, low waterborne Cu and low dietary Cu; triangles, low waterborne Cu and normal dietary Cu; open circles, normal waterborne Cu and low dietary Cu; filled circles, normal waterborne Cu and normal dietary Cu; squares, normal waterborne Cu and high dietary Cu level. *Significantly higher level, 
significantly lower level relative to the group exposed to normal water Cu and normal dietary Cu (ANOVA, P<0.05).
