| 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 mossambicus和食蚊鱼Gambusia 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 Island.[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 1 722 fish samples were collected, including 10 species.In addition to two invasive species, Oreochromis mossambicus and Gambusia affinis, the other eight species of native fish belonged 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 distribution. |
