中文摘要:
      可鲁克湖(以下简称克湖)位青海省柴达木盆地,海拔2800米,面积43~54平方公里,呈洼地型,最深8米,盐度0.79%。5~9月份最高月均水温通常在 18℃以下,但浅水区广阔,夏季晴天多,出现有较高的水温。湖内生物种类简单,多为广温、低温、广盐、淡水和喜清洁种,优势种数量大。因地理隔离等限制因子,地方鱼类仅有裸鲤和条鳅。1978年起引入鲤、鲫、鲢、鳙、草鱼、青鱼和团头鲂等,其中鲢、鳙、青鱼等引种失败;草鱼、团头鲂尚有成功的可能;鲤、鲫鱼已取得成功,且已能繁殖。要提高移植鱼类的成活率、生长率,以及湖泊生产力和经济效益等,还需要投放大规格鱼种,使之有面对高原环境条件新能力。另外,克湖要成为青藏高原优越的引种驯化基地,需要进一步寻找和探索适应高原环境的引种对象。这是一项十分有意义的工作。
英文摘要:
      Keluke Lake, located in tha hinterland of Qinghai--Xizang(Tibet)Plateau (2, 800m above the sea level),is the only freshwater body of the Qinghai Province. The lake water has very low of salinity (0.78%)and abundant in aquatic plants, zooplankton and zoobenthos, but only two species of local fishes, i. e.Gymnocypris and Nemachilus inhabit in the lake. However, the average water temperature is rather low (in May to September often below 18℃).Since 1973, many species of freshwater fish introduced into the lake, inclu-ding common carp, crucian tarp, silver carp, big head, grass carp, black carp and blunt-snout bream, in which common carp and crueian carp grow well and reached to sexual maturation in the Iahe, and. grass carp and blunt-snout bream grow well but not yet matured, but silver carp, big head and black carp seem, hard to be dome-stieated. For further exploitation of biological resources, an appropriate fish composition would be of great significance to increase the productivity of the Take and to establish a management and fishing organization far introduction and domestica-tion of suitable species.
