中文摘要:
      柔鱼是一种短生命周期的种类,具有产完卵后即死亡等特点,其种群资源量的大小完全取决于补充量的多少,而其补充量主要取决于其早期生活史阶段的死亡率。柔鱼作为重要的经济头足类,广泛分布在北太平洋海域,深入了解柔鱼早期生活史过程对于预测其来年资源补充量具有重要的作用。为此,主要回顾柔鱼早期生活史研究进展,重点讨论了柔鱼仔幼鱼的分布、摄食、年龄和生长、自然死亡率以及补充量与环境之间的关系,简单介绍了柔鱼胚胎生长发育过程和仔鱼形态变化。分析认为,柔鱼早期生活史中从产卵孵化、胚胎发育到仔稚鱼是一个非常重要也是最不被了解的生活史阶段,未来研究的重点应放在该阶段中仔鱼的生长死亡以及环境变化对柔鱼孵化成功率和资源补充量的影响。
英文摘要:
      Ommastrephes bartramii is a kind of short life cycle species which has the characteristics of dying immediately after spawning, and the stock size entirely depends on the recruitment, while the recruitment mainly depends on its mortality in the early life stage.Ommastrephes bartramii is an important economic cephalopod, and is widely distribute in the North Pacific Ocean, therefore understanding the progress of the early life history of Ommastrephes bartramii thoroughly can play an important role in predicting the changes of recruitment in the next year. For this purpose, this paper mainly reviews and discusses the distribution of paralarvae and juveniles of Ommastrephes bartramii, feeding, age and growth, natural mortality, and also the correlation between the environment and recruitment. This paper also gives a brief introduction to the progress of embryonic development and morphological changes of larvae. The early life history which is from spawning to hatching and embryonic development to grow to be larvae is a very important and least understood stage. Future research should focus on this stage by studying the growth and death of the larvae and the influence of environment changes on the squid hatching success, as well as the stock recruitment.
