When the surface temperature of water equaled to the optimum temperature of fishing, the depth of fishing became shallow, but in autumn never so. 4) The good fishing was in the current of NE~SE, but rhe small in NW~SW and S.}, pages = {26--32}, title = {鹿児島沿海の鯖漁況と水温, 流向について}, volume = {2}, year = {} }
