对大西洋鲱鱼种群结构的两个对立概念进行了批判性的回顾，目的是在集合种群概念下统一这些不同的观点。结论是，离散种群概念和动态平衡概念都不能很好地解释鲱鱼种群结构和动态的所有数据，包括分生和形态测量、生活史特征、归巢、年份双胞胎和生化分析。然而，现有的信息确实表明，集合种群概念很好地描述了大西洋鲱鱼的种群结构和动态。以同域季节性产卵种群为例，说明了在领养-迁徙假设下维持本地种群完整性和持久性的策略、机会和机制。通过行为隔离来维持当地种群的完整性，即重复而不是出生归宿到产卵区，而通过将迁徙模式和产卵区从成年个体向招募个体进行社会传递来确保当地种群的持久性
Two opposing concepts of Atlantic herring, Clupea harengus L., population structure are critically reviewed with the objective of unifying these divergent views under the metapopulation concept. It is concluded that neither the discrete population concept nor the dynamic balance concept adequately explains all the data associated with herring population structure and dynamics, including meristic and morphometric measurements, life- history traits, homing, year-class twinning, and biochemical analyses. However, the available information does suggest that Atlantic herring population structure and dynamics are well described within the metapopulation concept. The example of sympatric seasonal-spawning populations is used to illustrate the strategy, opportunity and mechanism by which local population integrity and persistence are maintained within the adopted- migrant hypothesis. Local population integrity is maintained through behavioural isolation, i.e. repeat rather than natal homing to spawning areas, while local population persistence is ensured through the social transmission of migration patterns and spawning areas from adults to recruiting individuals
