鲤鱼是我国重要淡水经济鱼类,深得广大群众喜爱。尤其在北方,鲤鱼的商品价值居淡水鱼首位。但由于鲤鱼对饵料中蛋白含量要求高(40—50％),而目前蛋白饲料又很难解决,因此长期以来,鲤鱼在养殖中只能作为一个少量搭配品种,而不能成为高密度高产主养对象。我所在承担农牧渔业部北方荷元鲤杂种优势大面积推广试验工作中,为了解决鲤鱼高密度养殖饵料问题,开展了以非蛋白态氮(尿素)替代蛋白,应用于鲤鱼人工配合饵料的专题研究,以寻求解决鲤鱼高蛋白饵料的现实途径。研究重点以鲤鱼肉营养分析为基础,探索尿素在人工配合饵料中合理的加 Carp is an important freshwater economic fish in China, won the majority of people love. Especially in the north, carp’s commodity value ranks first in freshwater fish. However, because of the high protein content (40-50%) of the carp diet, and the current protein feed is very difficult to solve, so for a long time, carp in the breeding can only be used as a small amount with varieties, but can not become a high-density high-yielding host Object I am responsible for the Ministry of Agriculture, Animal Husbandry and Fisheries North Dutch carp hybrid large-scale promotion of experimental work, in order to solve the high-density carp breeding bait problem, carried out with non-protein nitrogen (urea) instead of protein, carp manual application of bait Research in order to find a realistic way to solve the carp high protein bait. Research focuses on the carp meat nutrition analysis as the basis to explore the urea in artificial diet with reasonable
