几千年来，人类一直在海上跟踪鸟类以寻找鱼类和哺乳动物。海鸟是高度可见的广泛的上层营养级消费者，可以指示海洋生产力和生物相互作用。与鱼类、海洋哺乳动物和其他主要或完全生活在水下的动物相比，海鸟很容易调查、普查和研究。本章回顾了鱼类种群状况的鸟类指标的类型，效用和局限性，并建议进行研究，以提高对鸟类营养关系的理解。
For millenia humans have followed birds at sea to locate fish and mammals. Seabirds are highly visible wide-ranging upper trophic level consumers that can indicate marine productivity and biotic interaction. Compared with fish, marine mammals, and other animals that live primarily or exclusively underwater, seabirds are easy to survey, census and study. This chapter reviews the types, utilities and limitations of avian indicators of the condition of fish stocks and recommends research needed to improve understanding of avian trophic relationships.
