| Abstract: |
| The migration route of oceanic squid provides critical information for us to understand their spatial and temporal variations. Mark-recapture and electronic tags tend to be problematic during processing. Cephalopod hard structures such as the beak, containing abundant ecological information with stable morphology and statolith-like sequences of growth increments, may provide information for studying spatio-temporal distribution. In this study, we developed a method, which is based on elemental concentration of beaks at different ontogenetic stages and sampling locations, to reconstruct the squid migration route. We applied this method to Ommastrephes bartramii in the North Pacific Ocean. Nine trace elements were detected in the rostrum sagittal sections (RSS) of the beak using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). For those elements, significant differences were found between the different ontogenetic stages for phosphorus (P), copper (Cu) and zinc (Zn). Sodium (Na), P and Zn were chosen as indicators of sea surface temperature (SST) and a regression model was estimated. The high probability of occurrence in a particular area represented the possible optimal squid location based on a Bayesian model. A reconstructed migration route in this study, combining all the locations at different ontogenetic stages, was consistent with that hypothesized in previous studies. This study demonstrates that the beak can provide useful information for identifying the migration routes of oceanic squid. |

| 大洋性鱿鱼的洄游路径能够给我们重要的信息，帮助我们了解其时空分布的变化。标记-重捕和电子标记方法在施行过程中仍存在一些问题。头足类的硬组织，如角质颚，有着稳定的形态特征和类似耳石的连续生长纹，同时包含丰富的生态信息，可以为我们研究物种的时空分布提供相关信息。本研究中，我们以北太平洋柔鱼为研究对象，基于不同角质颚生长阶段进行取样来重建鱿鱼的洄游路径。研究结果认为，通过电感耦合等离子质谱仪（LA-ICP-MS）取样，发现角质颚的喙端矢状平面（RSS）检测到9种微量元素。针对上述几种元素，发现不同生长阶段的磷（P）、铜（Cu）和锌（Zn）存在显著差异。利用钠（Na）、磷和锌与海表面温度（SST）建立线性回归模型。基于贝叶斯模型，计算出不同时期柔鱼出现的较高概率的海域。结合不同时期的高概率分布海域，建立起柔鱼的洄游路径，该结果与前人研究结果一致。本研究也证实了角质颚可以为研究大洋性柔鱼的洄游路径提供有效的信息。 |
