| 摘 要： | 为了解黄河干流禹门口至三门峡河段渔业资源现状,于2012年5～9月对此河段的鱼类资源进行了调查。结果表明,该河段鱼类种群数量较小,鱼类资源下降严重,渔获物组成趋于小型化。鱼类区系组成简单,物种多样性较低,分布不均匀;通过分析该河段鱼类资源量衰退的原因,提出了针对该河段鱼类资源保护和渔业资源可持续利用的对策。

| Abstract: | In order to inquire the status of fishery resource from Yumenkou to Sanmenxia of mainstream of Yellow River,fish resources during May to Sep.in 2012 were investigated.The results indicate that： fish communities were seriously damaged and the composition tended to be smaller.The composition of fish fauna was single,the species diversity was low and distribution was uneven.Through analyzing reasons of fish decline in this reach,some measures were put forward aiming at protection of fish resources and sustainable usage. |
