Two experiments were conducted to study the effect of temperature on growth and survival of yearling sea bass, Lateolabrax japonicus reared from 3$^{circ}C$ to 33$^{circ}C$. In the I st experiment, we used yearlings fish averaging 19.2$pm$0.2 cm/fish (Mean$pm$S.E.M.) of total length (TL) and 67.0$pm$1.8 g/fish (Mean$pm$S.E.M.) of body weight (BW), and we cultured the fish at 3, 6, 9, 12 and 17$^{circ}C$ for 90 days. In the 2nd experiment, the experimental fish averaging 24.9$pm$0.1 cm/fish (Mean$pm$S.E.M) of TL and I 46.4$pm$3.0 g/fish (Mean$pm$S.E.M) of BW were reared at 21,24,27,30 and 33$^{circ}C$ for 90 days. During these experiments, we measured food intake, feed efficiency, survival and growth (TL and BW) in the both experiments. Although food intake of the yearling increased with the temperature, the feed efficiency was only enhanced within the temperature range, from 21 to 27$^{circ}C$. Growth of yearling was normal within the temperature range from 17 to 3$0^{circ}C$, but it was stoped or reduced in other temperatures. Survival rate was significantly reduced in 3$^{circ}C$ from the 1st experiment and in 30 and 33$^{circ}C$ from the 2nd experiment, but there was no significant difference among other groups.
