Data are presented as mean ± SE. Values with different lowercase superscripts (alphabet) differ significantly (𝑃<0.05) between fishes within tissue and concentration. Values with different numeric superscripts differ significantly (𝑃<0.05) between concentrations within tissue and fishes. Values with different uppercase superscripts (alphabet) differ significantly (𝑃<0.05) between tissues within fishes and concentration.
