| 摘要: |
| 哈纳斯湖位于新疆阿勒泰地区的布尔津县内，北纬48°43'—48°54'，东经86°59'—87°09'，全湖面积约45km2，平均水深120.1m，最大深度188.5m，为构造——冰川堰塞湖。1985年以来，因为“大红鱼”即哲罗鲑(Hucho taimen(Pallas))的发现而闻名。1987年8月和1988年7月笔者两次对该湖进行考察，据调查结果共见到浮游动物21种，其中原生动物1种，轮虫11种，枝角类6种，桡足类3种。全湖平均数量60.7个/L，平均生物量0.6499mg/L。此外，本文还对该湖浮游动物的水平分布和垂直分布特点进行了论述，对该湖的供饵能力进行了估算，有助于解开“大红鱼”的迷底。 |

| Abstract: |
| Hanasi Lake, located in Buerjin County, Aertai Region, Xinjiang Province, 48°43'-48°54'N, 86°59'-87°09'E, has an area of 45km2, average depth 120.1 m. and maximum depth 188.5 m, belonging to a tectonic-glacial deposit dam lake formed by glacial erosion. Since 1985, it has become famous for its discovering the "big red fish" (Hue ho taimen (Pallas)).Hanasi Lake was surveyed twice, in Aug. 1987 and July 1988. According to the analysis of samples, 21 speceis of zooplankton have been identified, among which, 1 species belongs to Protozoa, 11 to Rotifera, 6 to Cladocera and 3 to Copepoda. The average amount of zooplankton is 60.7 ind./L and average biomass is 0.6499 rag/L. In addition, this paper deals with the characters of horizontal and perpendicular distributions for zooplankton, and estimates the amount which acts as the bait for fishes. All these may help discover the “raddle” of the “big red fish”. |
