eel (Kitajima et al., 1967). Sequential metamorphic transitions of the conger
eel for four weeks induced by the treatment either with T
4
, or with the
anti-thyroidal drug thiourea, are shown in Fig. 11 (Yamano unpublished
Figure 10.
Changes in the levels of thyroxine (T
4
) and triiodothyronine (T
3
) during larval
and metamorphic development of the Japanese eel (
Anguilla japonica
). In order to group
the larvae, either TL (total length), or the ratio PAL (length from the proboscis to anus)/
TL % , were used for the fi sh, before and during metamorphosis, respectively. Numerals
in parentheses indicate the numbers of animals in each group. Bars indicate the means and
standard deviations. Asterisks in the upper graph and different letters on bars in the lower
graph indicate signifi cant differences (P < 0.05, Mann-Whitney
U
-test). The inset in the lower
graph is shown on a different scale of Y values. ND, non-detectable. Reproduced from Yamano
