| 摘 要： | 本文通过延时摄影技术探究了不同刺参规格（小规格、中规格和大规格）及饥饿状态（饥饿0 d、5 d、10 d和15 d）对其集群行为的影响。研究发现：不同规格刺参的聚集率和标准聚集规模之间存在显著差异（P<0.05），且呈现出随刺参规格增大而升高的趋势，表明大规格刺参更倾向于聚集，且形成的集群规模更大；除饥饿10 d和饥饿15 d的组外，各处理组之间刺参聚集率和标准聚集规模都具有显著差异（P<0.05），随着饥饿时间的延长，刺参聚集率和标准聚集规模呈先降低，后升高，再保持稳定的规律。上述结果查明了规格和饥饿对刺参集群行为的影响，可为丰富刺参行为学研究及优化刺参增养殖管理策略提供理论依据。

| Abstract: | This study investigated the effects of size (small, medium, and large) and starvation state (0, 5, 10, and 15 days of starvation) on the aggregating behavior of Apostichopus japonicus using time-lapse photography. Significant differences were found in the aggregation rate and typical aggregation size of A. japonicus of different sizes (P<0.05). The aggregation rate increased with the size of A. japonicus, indicating that large-sized A. japonicus tended to aggregate, and their aggregating size was large. The aggregation rate and typical aggregation size of A. japonicus in all treatment groups were significantly different (P<0.05), except for those starved for 10 and 15 days. Further, the aggregation rate and typical aggregation size of A. japonicus initially decreased, then increased, and then attained a plateau as the starvation time was prolonged. This study revealed the influence of size and starvation state on the aggregating behavior of A. japonicus. These results provide a theoretical basis for improving the behavioral research of A. japonicus and optimizing the management strategy for their breeding. |
