摘要
鲟类约有2亿年的历史，是现存脊椎动物中起源最早的生物类群之一，具有独特的生物学特性。近年来受水电工程建设、过度捕捞及环境污染的影响，鲟类的自然资源量日益枯竭，70%的种类被世界自然保护联盟（ IU C N）列为濒危乃至极危物种。本文综述施氏鲟 Acipenser schrenckii 的生物学特性和资源状况，阐述施氏鲟的分布、地理种群、形态特征、食性、年龄与生长、繁殖、洄游、资源现状及其下降的原因，以期为施氏鲟资源的合理利用及我国珍稀濒危鲟类的保护提供参考。
Abstract
The sturgeons, as the earliest existing vertebrates, about 200 million years of history, have formed unique biological charac-teristics. In recent years, the varieties of 70% sturgeons are listed as endangered species or critically endangered species by International Union for Conservation of Nature ( IUCN), as the natural resources of the sturgeons have been significantly declined with hydroelec-tricity project, overfishing and environmental pollution. In this article, biological properties and resources of Amur sturgeon( Acipenser schrenckii) are summarized, including distribution, geographic population, morphological characteristics, feeding habit, age and growth, reproduction, migration, resource status and the cause of the stock decline, in order to provide reference with both rational use of Amur sturgeon and development of sturgeon protection theory.
