| 摘 要： | 【目的】全面了解涠洲岛淡水鱼类的生物多样性。【方法】选择了10个调查位点,利用电鱼器和流刺网对涠洲岛的淡水湿地进行4个季度的全面采样。【结果】共计采到鱼类标本1 722尾、鱼种10种。除罗非鱼Oreochromis mossam bicus和食蚊鱼Gam busia affinis两种外来物种外,其他的8种本土鱼类分别隶属于4目7科8属。种类和数量在不同区域和季节的差异明显。【结论】涠洲岛淡水鱼类存在种类较少,生物多样性较低,物种分布不均衡的特点。

| Abstract: | [Objective]Studying the freshwater fish biodiversity comprehensively in Weizhou Is-land.[Methods]10 survey sites were selected,and the freshwater wetlands of Weizhou Island were sampled in four quarters using electric fishing instrument and gill nets.[Results]A total of 1722 fish samples were collected,including 10 species.In addition to two invasive species, Oreochromis mossam bicus and Gam busia affinis ,the other eight species of native fish be-longed to 8 genus of 7 families of 4 orders.The variety of fish species and quantity were obvious in different seasons and areas.[Conclusion]The results demonstrated that the characteristics of freshwater fishes in Weizhou Island were fewer species,low diversity and unbalanced distribu-tion. |
