Excerpt from Japanese Skipjack Studies: Translated From the Japanese Language
With regard to the relation between the skipjack fishing situation and oceanographic conditions, a great number of reports have been published in the past on surface water temperature, the present author himself having published frequently on the subject in this journal, however, there has not yet been any thorough study of factors other than surface tempera ture. For the determination as a practical problem of the zone which connects the principal skipjack fishing grounds the apparent fishway the surface water temperature values alone do not sufficeo Furthermore, in explaining the skipjack fishing situation in the Satsunan and Zuneh areas there is much that cannot be understood from the water temperatures aloneo Further there is the general problem of the relationship between oceanographic conditions and how well the skipjack take to the bait° If we try to make a start at solving the problems in such an area, we experience considerable difficulty because the threads of all of the factors are entangled and there is a paucity of data other than surface water temperatures. Nevertheless, feeling desirous of seizing a clue to the solution of these problems, I have made two or three preliminary investigations, the results of which are reported below.
