摘要

头足类动物在其生命早期所经历的气候变化对个体的生长有重要影响，其中温度是最重要的因素之一。本文研究了不同气候条件下水温对土sidicus gigas早期生长的影响。对2008 - 2010年在秘鲁采集的样本进行了地幔长度、年龄结构、地幔长度与体重的关系、初性成熟年龄以及幼虫和幼鱼阶段的生长率分析。结果表明，在幼虫期和幼期经历过El Niño事件的个体，其成年地幔长度较小，寿命较短，性成熟较早；而在幼虫期和幼期经历过La Niña事件的个体，其成年地幔长度较大，寿命较长，性成熟较晚。此外，我们发现样本采集地点的差异对成人年龄的影响更为显著。

Impact of water temperature experienced in early life of Dosidicus gigas on its adult growth

The climatic variations experienced by cephalopods in their early life have a significant impact on the growth of individuals, with temperature being one of the most important factors. This paper investigated the effects of water temperature under different climatic variations on the growth of Dosidicus gigas during early life stages. Samples collected off Peru from 2008 to 2010 were analyzed for mantle length, age structure, mantle length-body weight relationship, age at the first sexual maturity, and growth rates of paralarvae and juvenile stages. The results showed that individuals experiencing El Niño events during paralarvae and juvenile stages had smaller adult mantle length, shorter lifespan, and earlier sexual maturity, while those experiencing La Niña events during paralarvae and juvenile stages had larger adult mantle length, longer lifespan, and later sexual maturity. In addition, we found that differences in sample collection locations had a more significant effect on adult age.

期刊介绍： This journal provides an international forum for the publication of papers in the areas of fisheries science, fishing technology, fisheries management and relevant socio-economics. The scope covers fisheries in salt, brackish and freshwater systems, and all aspects of associated ecology, environmental aspects of fisheries, and economics. Both theoretical and practical papers are acceptable, including laboratory and field experimental studies relevant to fisheries. Papers on the conservation of exploitable living resources are welcome. Review and Viewpoint articles are also published. As the specified areas inevitably impinge on and interrelate with each other, the approach of the journal is multidisciplinary, and authors are encouraged to emphasise the relevance of their own work to that of other disciplines. The journal is intended for fisheries scientists, biological oceanographers, gear technologists, economists, managers, administrators, policy makers and legislators.
