| Research Abstract |
We planned to investigate effects of endocrine disrupting chemicals (EDCs) and grovel warming on fish reproduction and next generation production in East Asia. In this experiment including oversea research, we used endocrine, physiological, and histological methods for obtaining the information about EDCs and water temperature effects. The grey mullet, Japanese common goby, groupers, dojo loach were selected as a suitable wildlife for these experiments and survey. In this project, EDCs contamination was observed in coastal waters in East Asia, and influence of grovel warming on fish reproduction, such as a changes in spawning period, an induction of abnormality in early development, a reduction of ovulated eggs, were indicated. In addition, fish reproduction was inhibited by the combined effect of high temperature and EDCs.
