<![CDATA[Objective of this research was to know the role of iodine with different doses and exposed duration to against the rate metamorphosis and survival of bullfrogâs tadpoles. Methods on this research are acclimatization of bullfrogâs tadpoles, given iodine solution such as doses 3 mg/L, 4 mg/L, 5 mg/L and control (0 mg/L). It observe on 7th, 14th and 21st day of to exposed. The parameters that observed there are tadpole metamorphosis, survival rate and water quality. Data were analyzed using two-way ANOVA and continued with Tukey test. The results showed that water quality on a good category for bullfrog of natural environment. ANOVA for bullfrog metamorphosis rate obtained at p-value (< 0.05). Duration of exposed and doses are significantly influent to against bullfrogâs tadpoles metamorphosis. Although survival rate of bullfrog tadpoles was decline at 21th duration and survival rate of bullfrogâs lowest in doses 5 mg/L. The conclusion is treatment of iodine solution at given in the medium of life bullfrogâs tadpoles and exposed duration of iodine can increase the rate of metamorphosis, but inclined decrease survival rate of bullfrogâs tadpoles. Iodine solution most effect on the rate metamorphosis bullfrogâs tadpoles on exposed 7th, 14th and 21st days on the doses of iodine solution 5 mg/L (5 ppm), while survival rate of bullfrogâs tadpoles is the highest on treatment control (0 mg/L). ]]>
