This paper was extracted and rearranged from the papers mainly published on academic journals and organs of research papers from 1980 to 1990. The contents of this paper are based on oceanophysics and chemistry and describe the results of fisheries research institutes and prefectural fisheries experiment stations. The main results are as follows. 1) The specification of the appearance region of the cold water mass formed in the northern marginal part of the Kuroshio accompanied by the separation and approach of the Kuroshio with respect to the shore. 2) The patterning of the trend of the Kuroshio branch stream or warm water derived from the Kuroshio to a coastal region at every sea areas of each place. 3) The formation of the mean image of the water temperature distribution or flow in Tosa Bay. 4) The above mentioned results are put to practical use as data for estimating the fluctuations in the separation and approach of the Kuroshio with respect to the shore or the meandering of the Kuroshio, the affecting situation of a warm water to a coastal region accompanied thereby and the short-term change of coastal sea conditions. 5) In order to grasp the short-term fluctuations in the sea conditions of south and west open sea and to enhance the estimation accuracy of sea conditions such as the meandering of the Kuroshio or the fluctuations in coastal sea conditions, it is of urgent necessity to keep and fill up investigation and study at the present time asked for social correspondence on a international scale
