Fig. 7. Carcass Cu concentration (µmol g^–1wet mass) during the exposure period (A) and the proportional contribution of the carcass to the total Cu burden during the exposure period (B). Carcass comprised whole body less gill, liver and gut. Percentage data were transformed to arc sin for statistical analysis. All the values are means ± S.E.M., N=15 for weeks 0, 2 and 4, and N=9 for week 7 for each of the 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 on normal levels of water Cu and dietary Cu (ANOVA, P<0.05).
