| 摘 要： | 应用生态学方法对鸭绿江花羔红点鲑Salvelinus malma(Wabum)、细鳞鱼Brachymystax lenok(Pallas)和长白哲罗鱼Hcho ishiawai Mori的繁殖策略进行了研究。结果表明：3种鱼的繁殖策略表现在初次性成熟年龄和规格、繁殖季节、产卵式型和个体绝对繁殖力方面各不相同，而产卵场及其条件和繁殖方式及行为大致相同，是其自身固有物种特性在同一水域适应生态环境的具体表现，充分发挥了不同鱼类利用同一水域空间、时间和铒料生物的潜力。

| Abstract: | The reproductive strategies of S.matma,B.lenok and H.iskiawai in Yalu River were studied by means of biology methods. The result showed that the reproductive strategies including ages and size at sex mature,reproductive season,spawing types and absolute fecundity are different while that spawing ground coiditions, way of reproduction and action are similar.It is showed that special features of different fishes were evoluted to adapt to the ecological environment in the same water body, thus bring into full use of the potentiality of space, season and food organisms of water body in Yalu River by different fishes at the same time. |
