概要

This paper shows the result of analysis using a number of data which have been investigated by the Osaka-Prefectural Fisheries Experimental Station for long years. The temporal and spatial characteristics of the environment of Osaka Bay are clarified by multivariate analysis technique. The results show that phytoplankton and nutrient are principally important of course, and the features of the water quality are different depending on location. The seasonal change is also shown that the phytoplankton increases from spring to autumn, and nutrient increases from autumn to winter. The degree of the seasonal change in the recesses of the bay is very larger than that in the mouth of the bay. Furthermore, the results of water density clarify the spatial-temporal characteristic of water body in Osaka bay.
