| 摘 要： | 耳石是头足类重要的硬组织之一,存储了大量微化学信息,能够反映其栖息环境变化,是研究头足类生活史的重要材料。本文根据2017年3月—5月我国灯光罩网渔船于中国南海南沙群岛海域采集的1002尾鸢乌贼样本,利用激光剥蚀电感耦合等离子质谱法(LA-ICP-MS)分析了17枚鸢乌贼耳石微量元素的组成及分布。结果表明：南沙群岛海域的鸢乌贼耳石主要由56种微量元素组成,含量最多的前10种元素依次为钙(Ca)、锶(Sr)、钠(Na)、磷(P)、硅(Si)、钾(K)、镁(Mg)、铁(Fe)、钡(Ba)和硼(B)。方差分析表明,不同性别间Ca、Sr、Na、P、Si、K、Mg、Fe、Ba、B的分布均无显著性差异；不同孵化期的群体间Ca、Sr、Na、P、Si、K、Mg、Fe、Ba、B的分布也无显著性差异；不同耳石部位间Si、K、Fe无显著性差异,而Ca、Sr、Na、P、Mg、Ba、B则有显著性差异。

| Abstract: | Statolith is one of the most important hard tissues of cephalopods containing abundant microchemical information, which could reflect the habitats environment change, was widely used in the research of cephalopods life history. Elements of 17 statoliths of Sthenoteuthis oualaniensis collected in the Nansha islands waters of the South China Sea during March to May by the falling-net fishery of 2017 were analyzed with Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) for different sexes, different hatching groups and growth zones. The results showed that the statolith of S. oualaniensis contained 56 elements, and calcium(Ca), strontium(Sr), sodium (Na), phosphorus(P), silicon(Si), potassium(K), magnesium(Mg), iron(Fe), barium(Ba) and boron(B) were the most abundant ten elements. The analysis of variance (ANOVA) showed that there was no significant difference in all element distributions between sexes and different hatching groups for the most abundant ten elements. There were significant differences in the contents of Ca, Sr, Na, P, Mg, Ba and B, but no significant difference in the contents of Si, K and Fe in the statolith among different growth zones. |
