托洪台水库鱼类区系和种群组成

于2012年5月、8月对新疆阿勒泰地区布尔津河流域托洪台水库进行了为期一年的水生生态监测工作,重点开展了鱼类区系和种群组成特征研究工作,发现托洪台水库共有鱼类17种,其中土著鱼类有15种,分属北方平原复合体、北方山麓复合体、北极淡水复合体;非原额尔齐斯河流域早期土著鱼类2种,分属江河平原复合体、欧洲复合体。种群组成特征表现出以额尔齐斯河土著鱼类为主,以适宜冷水性、亚冷水性鱼类种类为主,但鱼类小型化严重,大个体土著鱼类种群资源量急剧下降。

Fish fauna and population composition of Tohongtai Reservoir

The research team conducted a one-year aquatic ecological monitoring work on the Tohongtai Reservoir in the Burqin River Basin in the Altay area of Xinjiang in May and August 2012,focusing on the research on fish fauna and population composition characteristics.The results show thay there are 17 species of fish in the Tohongtai Reservoir,including 15 species of indigenous fish,belonging to the Northern Plains Complex,the Northern Foothill Complex,and the Arctic Freshwater Complex;two species of early indigenous fish in the non-formal Irtysh River Basin.It belongs to the River Plain Complex and the European Complex.The characteristics of the fish population composition are mainly based on the indigenous fish of the Irtysh River.The species are mainly suitable for cold water and sub-cold water fish,but the miniaturization of fish is serious,and the resources of large individual indigenous fish populations have dropped sharply.
