京都大学濑户沿岸实验所在畠岛实验场开始了海岸生物的“一世纪间调查”的预备性调查。目前,以上述预备调查作为基础资料,正在进行水质变化对海胆卵的受精、生长的各种影响为基础的海水污染调查。现在,可能认为海水污染程度似乎不是那么严重的。但重要的 The Seto Coast Laboratory, Kyoto University, started a preparatory survey of “first-century surveys” of coastal organisms at the Hiroshima Laboratory. At present, based on the above preliminary survey as the basic data, a survey on seawater pollution based on the various effects of water quality changes on the fertilization and growth of sea urchin eggs is being conducted. Now, it may seem that the pollution of the sea does not seem so serious. But important
