Growth of juvenile red sea bream <i>Pagrus major</i> during the period from 1983 to 1993 was investigated in relation to sea water temperature and distribution density in the Bingo-nada area of the Central Seto Inland Sea. The temperature condition was evaluated as the sum of every ten days' water temperature anomaly from average values during the period from 1967 through 1982. The juveniles recruited from small-trawl fishing grounds in July had average fork length ranging between 47 and 63mm. At the end of the year, average fork length varied considerably between 96 and 131mm. Both correlation coefficients, between fork length and sum of temperature anomaly and density, were significant at the 5% level. Based on these results, a multiple regression formula was developed whose criterion variable was the maximum length (<i>FL</i> in mm) of red sea bream at 0 age, and three predictor variables were water temperature anomaly in July (<i>WT</i>), the number of catch in October (<i>C</i>) and the size of fish in July (<i>L</i>). The formula was <i>FL</i>=5.018<i>WT</i>-8.471<i>C</i>-4.917<i>L</i>. In this formula <i>L</i>, <i>WT</i>, and <i>C</i> were standardized by (original value-average)/standard deviation. It is statistically reasonable that the maximum length can be estimated by these 3 variables because each of the partial regression coefficients were significant at the 5% level.
