摘　　要：【目的】从栖息地角度解析东海带鱼种群变动的原因,揭示东海带鱼资源变动的主要影响因子。【方法】通过综述我国60多年的东海带鱼研究成果,从栖息地选择、种群数量年间波动、生物学变化等角度阐述东海带鱼对栖息地环境变化的适应性表现。【结果与结论】揭示东海带鱼“衰而不竭”除了与带鱼偏r-选择型的生活史特征和摄饵可塑性强的习性有关外,还与其较强的栖息地环境适应性有关,其中温度、盐度和饵料对带鱼的影响较明显。现阶段应重点从海流(温度、盐度)和关键饵料生物历史变化等角度揭示东海带鱼资源变动的原因,为东海带鱼资源保护和生境修复提供科学依据。【Objective】Trichiurus lepturus is the most important traditional commercial demersal fish in the East China Sea.The resources have experienced a decline in CPUE,miniaturization in catches,younger age,and premature sexual maturation since the mid-1970s.However,its fishing production can still be maintained,and it is the largest fishery in the East China Sea.This study aims to reveal the reasons for the“failure and endless”.【Method】This paper expounds the adaptive performances from the perspectives of habitat selection,population fluctuations,and biological changes by reviewing the research findings on Trichiurus lepturus in the East China Sea for more than 60 years.【Result】This review shows that the“failure and endless”of T.lepturus in the East China Sea is related to its strong habitat adaptability,in addition to its r-selective life history characteristics and the strong feeding plasticity.The effect of temperature,salinity and fodder on Trichiurus lepturus is obvious.【Conclusion】At this stage,we should reveal the habitat adaptability of T.lepturus focusing on the changes in current(temperature,salinity)and key fodder zooplankton in the East China Sea.This will provide a scientific basis for the protection of the fish resources and habitat restoration in the East China Sea.
