Interannual variation in the recruitment per spawning is positively correlated with the 10 m-depth temperature in the central area of Ise Bay in February, 5 m-depth salinity in the central area in March and 10 m-depth salinity in the bay head in April, and negatively correlated with the 30 m-depth temperature in the central area in July. On the basis of the results in a stepwise multiple linear regression analysis, we hindcast the recruitment per spawning from 1993 to 2012 using the temperature and salinity around Ise Bay. Key words: Takifugu rubripes, recruitment per spawning, temperature, salinity, Ise and Mikawa Bay
