鱼用人工配合饲料的使用和遗传育种等技术的应用,大大推动了池塘养鱼业的发展,改变了产品结构组成,导致了生产模式的变化.1987年,我们在伊宁市水产养殖场进行了池塘养鲤试验.一、试验方法供试的镜鲤、兴国红鲤、杂交一代鲤和鲢鳙春片鱼种均由伊宁市水产养殖场繁殖,其中镜鲤亲鱼捕自伊犁河,兴国红鲤最早引自武汉东西湖水产养殖场,经该场多年培育提纯.试验鱼池3.8亩,最大水深1.7米,平均亩放春片鱼种75公斤,以鲤鱼为主,另搭配20%滤食性鱼类(表1).
Fish with artificial feed and the use of genetic breeding and other technology applications, greatly promoted the development of pond fish farming, changing the composition of the product structure, resulting in changes in production patterns. In 1987, we were in Yining aquaculture farms The pond carp test.First, the test method for the test of the mirror carp, red carp Xingguo, crossbred carp and silver carp and bighead carp spring fish species are from Yining aquaculture farms, mirror carp captured from the Ili River, rejuvenating the country Red carp was first introduced from Wuhan East Lake aquaculture farms, after years of cultivation and purification of the field test fish ponds 3.8 acres, the maximum depth of 1.7 meters, the average mu of spring sewer species 75 kg, mainly carp, the other with 20% filter feeding Fish (Table 1).
