摘要：

依据鱼类的繁殖习性及其早期发育阶段的适应特征，将长江中的8目17科90种鱼类划分为3个行为类型，13个繁殖共位群。其中鲤形目鱼类的86.9%属于无亲体护卫型繁殖类群，多为适应长江干流环境的漂浮性产卵类群以及适应湖泊定居的喜石性产卵类群与喜植性产卵类群。与现有的分类系统相比较，鱊亚科的全部种类仅局限于同一个繁殖共位群中，而鮈亚科的种类则分布于5个不同的繁殖共位群。对不同水系繁殖共位群的组成进行了比较。此外，讨论了不同繁殖共位群的生态适应性，及其在长江流域鱼类资源保护中的应用。

Abstract:

According to reproductive habits and adaptation in the early development stage,the fishes in the Yangtze River,including 8 orders 17 families 90 species,were divided into 13 reproductive guilds,about 393% kinds of the total species in the river.869% species of the Cypriniformes belong to nonguarded type.Most of them are pelagophils,lithophils and phytophils,adapting to dwell between lakes and rivers respectively.Compared with current classification system,species of Acheilognathinae limited to only one reproductive guild,while the species of Gobioninae scatter into five guilds.The different components of reproductive guilds in different fauna are compared.Furthermore,the ecological adaptation of different reproductive guilds and the application on protection of fish resources in the Yangtze River were discussed
