2009年6月和11月在葛洲坝上下游江段使用SIMRAD EY60回声探测仪对鱼类时空分布进行水声学调查。结果显示,葛洲坝上下游江段鱼类密度范围分别为2.8~122.7、8.8~888.8 ind./1 000 m3。上下游江段鱼类呈区域性分布,主要集中在西陵峡口、大江电站下游及三江等水域。大江电站下游流水区,鱼类一直集中在中下层。而在其它的静水和缓流区,6月份鱼类主要分布在中上层水域,11月份鱼类较为集中在中下层。6月份鱼类体长与分布水深无相关性(P>0.05)或负相关(P<0.05),11月份体长与分布水深均呈正相关(P<0.05)。根据结果分析,由于葛洲坝上下游水文情势的差别,分布有不同生态类群的鱼类,因此形成区域性的水平分布。在静水和缓流区,垂直分布还存在季节间的变化。季节变化还对葛洲坝上下游江段鱼类体长与分布水深的关系有明显影响 |

Four hydroacoustic surveys were conducted in June and November 2009 by using the SIMRAD EY60 echo sounder with a 200 kHz split-beam transducer in the upstream and downstream of the Gezhouba Dam in the Yangtze River in order to understand the temporal and spatial distribution of fishes.The result indicated that the average individual density (total fish number in a given water area)ranged from 2.8 to 122.7 ind./ 1 000 m3and 8.8 to 888.8 ind./1 000 m3in the upper and lower reaches of the Gezhouba Dam,respectively.Fishes unevenly distributed in the investigated area and mainly concentrated in three sections,which were the mouth of Xiling Gorge,tailwater of Dajiang power plant and Sanjiang section.Fishes always concentrated in the middle and bottom layers of the lotic reach below Dajiang power plant.In the sections of the slow-flow and lentic sections,fishes preferred to middle and surface layers in June but bottom layer in November.Fish body length was not correlated (P>0.05)or negatively correlated (P< 0.05)with water depth in June.However,there were positive correlations (P<0.05)between them in November.It is suggested that the fishes which were suitable for the different ecological groups were regionally distributed in horizontal direction due to the different hydrological regimes of the upper and lower reaches of Gezhouba Dam.In the sections of the slow-flow and lentic sections,there was variation of the vertical distribution between seasons.The seasonal variation also influenced significantly the relationship between fish body length and distributing water depth in the upper and lower reaches of Gezhouba Dam. |
