In order to know the relationship between the fluctuations in catches of the yellow tail, Seriola quinqueradiata T. and S. and sea conditions in the Meshima fishing ground in the East China Sea, the catch records of the yellow tail have been dealt. Although the periodicity of the fluctuation in catches is not obvious, a correlation between the catch and the number of sun spots is recognized to some extent. High catch of the yellow tail in the Meshima Is. arises during the transitional period from the year of the maximum number of the sun spots to the year of these minimum number, and the low catch arises during the period from the year of those minimum to the year of the maximum. Relationships of the fluctuation in catches to that of the warm Tsushima Current have been unable to make clear.
