| 摘 要： | 于2010年9月～12月和2011年3月～6月对贵阳市红枫湖的鱼类资源进行了调查,捕获鱼类28种,分属于4目6科;鱼类的体长为5.68～116.41 cm,优势体长组为11.00～30.00 cm,其中小型鱼体和中大型鱼体占多数。2011年6月运用BioSonics DT-X（200 kHz）鱼探仪对鱼类密度进行了水声学探测,平均密度为（51.64±36.49）×10-3尾.m-3,不同区域的鱼类密度分布有显著性差异,最大值出现在将军湾（97.25±12.35）×10-3尾.m-3],最低值位于红枫湖大坝（14.90±2.56）×10-3尾.m-3],从大坝到将军湾鱼类资源量总体上呈现逐步增长的趋势。红枫湖鱼类分布水层主要在6～15 m,不同水层的鱼类密度分布存在显著差异。 |

| Abstract: | We observed the fish resource in Hongfeng Lake in Guiyang city during September～December,2010 and April～June,2011.Twenty-eight species which belong to 4 orders and 6 families were caught.The fish body length ranges from 5.68 cm to 116.41 cm,and that in dominant body length group is 11.00～30.00 cm;small,large and medium-sized fish are in the majority.Moreover,we used BioSonics DT-X digital scientific echosounder with 200 kHz split beam transducer to investigate the fish density in June,2011.The average fish density is（51.64±36.49）×10-3 ind · m-3 and significant difference in fish density is found in different areas,with the maximum at Zone Jiangjunwan （97.25±12.35）×10-3 ind · m-3] and the minimum at Zone Daba （14.90±2.56）×10-3 ind · m-3].From Daba to Jiangjunwan,the density of fish resource shows an increasing trend.The fish mainly distribute in 6～15 m.The fish density is signifcantly different among different water layers. |
