自1980年云南滇池移殖太湖短吻银鱼获得成功后,北方各地相继进行了移殖该鱼的研究,但至今尚没有一地获得生产性成果,在此情况下,我们分析了各种银鱼的生物学特性,选择了冬季产卵类型的大银鱼作为向北方移殖的对象。自1985年开始在内蒙古岱海进行试验,于1989年获得初步成效,当年夏又与北京水产局进行协作选择大银鱼往北京地区移殖。1989年12月—1990年1月我校首次将大银鱼受精卵300万粒通过控温贮存,保温运输等技术手段投放于北京平谷县海子水库,当年秋就捕得成体,第二年(1991年)捕得100
Since the success of transplanting the Taihu white-bellied silverfish in Dianchi Lake in Yunnan in 1980, research has been conducted on the transplanting of the fish in various places in the north of the country. However, no productive result has yet been obtained so far. In this case, we analyzed various silver The biological characteristics of the fish, the selection of the winter spawning type of silverfish as the object of migration to the north. Experiments began in 1985 in Daihai, Inner Mongolia and achieved initial success in 1989. In the summer of the same year, it collaborated with Beijing Bureau of Fisheries to select the giant silverfish to migrate to Beijing. 1989 December - 1990 January for the first time my school will Silverfly fertilized eggs 3000000 by temperature storage, thermal transport and other technical means put Beijing Haizi Reservoir in Pinggu County, then trapped in the autumn adult, the second year ( 1991) captured 100
