Three purified diets each containing testosterone, estrone, or estradiol at the level of 4.55×10<SUP>-6</SUP> g steroid/g wet diet and an ethanol-treated diet as a control were fed to juvenile sea urchin, <I>Pseudocentrotus depressus</I> for 29 days to examine their influence on growth and food utilization. The sea urchins treated with estrone showed significantly higher body weight than the control group (<I>p</I> < 0.05) . Food intake and feed efficiency in the estrone-treated group were the highest among the four groups. The growth of the sea urchins treated with testosterone was slightly higher but not significantly different from that of the control group. Estradiol had no effect on growth and food utilization of juvenile sea urchin.
