Influence of ocean warming on fish reproduction: international joint survey in East Asian region

我们计划调查内分泌干扰物（EDCs）和全球变暖对东亚鱼类繁殖和下一代生产的影响。本实验结合国外的研究成果，采用内分泌、生理和组织学方法，获得了内分泌干扰物和水温效应的信息。乌鱼、日本虾虎鱼、石斑鱼、道场鳅等为适宜的野生动物。本项目在东亚沿海沃茨观测了内分泌干扰物的污染情况，并指出了底层水温升高对鱼类繁殖的影响，如产卵期的改变、早期发育异常的诱导、排卵卵的减少等。此外，高温和内分泌干扰物的共同作用抑制了鱼类的繁殖。

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.
