摘　　要：太阳长棘海星(Acanthaster cf. solaris)灾害暴发是导致南海珊瑚礁退化的主要原因之一,开发太阳长棘海星灾害防控技术具有重要意义。本研究搭建了太阳长棘海星行为学室内研究平台,发现鹿角杯形珊瑚(Pocillopora damicornis)对太阳长棘海星的诱导聚集效果要强于丛生盔形珊瑚(Galaxea fascicularis)和澄黄滨珊瑚(Porites lutea)(P <0.05)。同时,收集鹿角杯形珊瑚黏液,利用羟丙基甲基纤维素等试剂制备了珊瑚黏液缓释剂,发现其对太阳长棘海星有明显诱导聚集效果(P <0.01),且硬度较低、缓释速率较快的缓释剂团块对太阳长棘海星的诱导聚集效果更明显。本研究开发了1种珊瑚黏液缓释剂的制备方法,证明了鹿角杯形珊瑚黏液能够显著诱导太阳长棘海星发生群体聚集,为太阳长棘海星的群体聚集机制的解析和灾害防控技术的创新发展提供了科学依据。Acanthaster cf.solaris disaster outbreak is one of the main causes of coral reef degradation in the South China Sea,so it is of great significance to develop a disaster prevention and control method for A.cf.solaris.An indoor research platform for A.cf.solaris behavior was set up,and it was found that Pocillopora damicornis had a higher effect on inducing aggregation of A.cf.solaris than Galaxea fascicularis and Porites lutea(P<0.05).At the same time,a sustained-release agent was prepared from coral mucus by using hydroxypropyl methyl cellulose and other reagents.It was found that the sustained-release agent with lower hardness and faster sustainedrelease rate had a significant effect on inducing A.cf.solaris aggregation(P<0.01).In summary,a preparation method for a sustained-release agent from coral mucus was developed,and it was proved that the coral mucus of P.damicornis could significantly induce A.cf.solaris population aggregation,which provides a scientific basis for the analysis of A.cf.solaris population aggregation mechanism and the innovative development of disaster prevention and control method.
