【摘要】 在广东大亚湾核电站温排水排放前、后，自１９９３年１月２０日至１９９５年２月２８日对该站附近水域１４个站位共进行６个航次的采样调查，收集鲷科鱼卵、仔鱼样本和同一站位的水温资料。结果表明，各站位的绸科鱼卵、仔鱼的分布在温排水排放前、后与水温变化密切相关。水域升温２—８℃对鲷科鱼类的产卵、孵化和仔鱼生长发育有明显的影响。鉴于目前升温水域范围只限在２ｎｍｉｌｅ内，可以认为整个大亚湾鲷科鱼类的资源和补充尚未受到较大的影响。更多还原

【Abstract】 his paper presents the investigation on the influences of thermal water from the nuclear power station on the distribution of fish eggs and larvae of Sparidae and temperature at fourteen sampling sites in Daya Bay.This investigation includes six voyages for collection of egg and larval samples as well as temperature data.The investigation shows that the distribution of fish eggs and larvae of Sparidae has significant correlation to that of temperature.The spawning, hatching and growth of larvae should be obviously affected in circumstances where temperature is raised 2-8℃.However, since water temperature rising area is restricted within a scope of 2 nautical miles at present, it might be considered that the resource and recruitment of Sparidae fish in Daya Bay has not been considerably affected.更多还原
