摘　　要：鲎是珍贵的海洋“活化石”生物。本研究于2014—2020年在广西北海山口红树林生态自然保护区开展圆尾蝎鲎(Carcinoscorpius rotundicauda)种群动态调查。总计观察到圆尾蝎鲎990只,种群数量呈现逐年下降趋势,其中第6个调查年相比第1个调查年下降94.60%,表明圆尾蝎鲎资源保护已势在必行;雄鲎占80.28%,雌鲎占17.50%。圆尾蝎鲎种群动态呈现显著季节规律性,种群数量与温度及北风和南风风向状态值(0和4)呈显著正相关,显示出滨海风向标生物特征。本研究揭示了圆尾蝎鲎种群动态及其影响因素,为保护区鲎资源保护提供参考依据。Horseshoe crabs are precious marine ‘living fossil’. Little information is available on dynamics of Carcinoscorpius rotundicauda population. During the period of 2014 to 2020, we monitored C. rotundicauda population at Shankou Mangrove Reserve in Behai, Guangxi. A total of 990 individuals of C. rotundicauda were recorded, with a declining trend of the population. In the sixth survey year, the population decreased by 94.60% compared with that in the first survey year, indicating that the conversation of this species is imperative. Male accounted for 80.28% of the total individuals, while females accounted for 17.50%. The population of C. rotundicauda fluctuated seasonally, and the population size was significantly positively correlated with temperature and the north and south wind direction states(0 and 4), suggesting biological characteristics of coastal vane for C. rotundicauda. This study help understand the population dynamics of C. rotundicauda and its influencing factors, providing reference for the protection of C. rotundicauda resources in the reserve.
