Fig. 2. Tissue distribution of the radioactivity, shown as the percentage of the
total dose injected in the fish per gram of tissue at 2, 24, 48 and 96 h after
i.p. 125I injection in tilapia (A, N=6) and carp (B,
N=6). Results are means ± s.d. One-way ANOVA was used for
statistical evaluation. Asterisks show significant difference compared with
the radioactivity level at 2 h (*P<0.05,
**P<0.01, ***P<0.001).
