中文摘要：

柔鱼是重要的大洋性经济头足类,是我国远洋鱿钓渔船的主要捕捞对象。对北太平洋柔鱼的种群结构、洄游、年龄与生长、繁殖、摄食等生物学研究进展做了初步总结和归纳,并提出需要进一步深入研究的方向,供今后研究参考。柔鱼可分为4个季节性地理种群,即秋生东部群体、秋生中部群体、冬春生西部群体和冬春生中东部群体,但还需要在分子生物学角度得到进一步的确认;柔鱼随季节做南北洄游,其中向北索饵洄游模式研究较为深入,而向南产卵洄游模式尚不清楚,其产卵场空间分布及产卵期需要进一步调查;对柔鱼繁殖习性研究相对不足,尤其是产卵至孵化以及孵化后至仔鱼的生活史过程;柔鱼分布的东西海洋环境差异很大,不同海域柔鱼的昼夜垂直移动规律还需要深入;柔鱼年龄约为1年,为短生命周期种类,其年间资源补充量变化的机理及其与环境关系初步得到掌握。为了更好地开发和利用该资源,需要加强各国之间的合作,系统地开展北太平洋柔鱼资源调查和渔业生物学研究,建立基于海洋生态系统的柔鱼资源监测网络,建立符合柔鱼生活史特征的资源量评估模型及其管理策略。

英文摘要：

Ommastrephes bartramii is an important economic cephalopod and also one of main fishing targets for Chinese squid jigging fleets.The knowledge of fishery biology is a basic condition for sustainable exploitation and utilization.The literature of population structure,migration,age and growth,spawning,feeding of O.bartramii has been reviewed,and comments and suggestion are provided in this paper.O.bartramii in the North Pacific Ocean can be sorted into four seasonal geographic cohorts,i.e.eastern stock of the fall cohort,central stock of the fall cohort,western stock of the winter-spring cohort and central-eastern stock of the winter-spring cohort.This classification need to be confirmed by the method of molecular biology.Generally,the squid made north-southward migration,the northward migration during the feeding period has been studied extensively;however the southward migration during spawning period was not clearly investigated,so the investigation on the temporal and spatial distribution of spawning ground is needed.Moreover,it is proposed that the spawning behavior of O.bartramii should be further studied,especially on the biologic process from spawning to hatching and paralarvae.The living environment of O.bartramii between west and east Pacific is different;the diel movement in the different areas has not been fully understood.The life span of O.bartramii is about one year.The inter-annual variability on recruitment of O.bartramii and its relationship between marine environments have initially been mastered.For the purpose of sustainable utilization of this squid,the international cooperation is needed to conduct fisheries survey and biological study on O.bartramii,and it is also needed for us to develop the squid fisheries ecosystem monitoring program and establish assessment model based on the life history characteristics and management strategy evaluation model.
