摘　　要：根据2016-2018年度调查获得的博斯腾湖和乌伦古湖增殖放流、捕捞数据,评价了两湖区近年来增殖放流的效果。结果显示,两湖增殖放流的均以外来经济鱼类为主。其中,乌伦古湖增殖放流鲢、鳙,增殖效果差、难以提升湖区的有效渔获量;博斯腾湖总蓄水量的减少,导致湖中的饵料生物量下降,加上池沼公鱼的饵料生物竞争,增殖放流效果不显著。针对以上问题,建议博斯腾湖减少草鱼的投放量,维持或适度降低鲢、鳙鱼的放流量,加大土著鱼类的放流力度;建议乌伦古湖减少或停止鲢、鳙鱼的投放;增加大规格土著鱼类的增殖放流数量。According to breeder releasing and fishing statistics of the Bosten Lake and Ulungur Lake from 2016 to 2018, this paper evaluates the effectiveness of breeder releasing in these two lake areas in recent years. Data analysis shows that breeder releasing in these two lake areas are mainly external economic fish species. Among them, the proliferation of silver carp and bighead carp in Ulungur Lake is poor, and it is difficult to improve the effective catch in the lake area. The decrease of the total water storage of Bosten Lake resulted inthe decrease of the food biomass. At the same time, the effect of fish breeder releasing is not significant due to the competition of bait organisms of pond fish. In view of the above problems, it is suggested that Bosten Lake should reduce the amount of grass carp, maintain or moderately reduce the discharge of silver carp and bighead carp, and increase the release of local fish. Also, it is suggested that the release of silver carp and bighead carp should be reduced or stopped in Ulungur Lake, and the quantity of large-scale local fish should be increased.
