轮虫、棱角类、桡足类,是鱼苗鱼种现成的活饵料,因其含有大量维生素、酶、微量元素等活性物质,以及蛋白含量高、氨基酸配比极为合理,是任何商品饲料所不能比拟的。但其缺点显而易见,即天然产量不稳定性,需要时不能大量供给,甚至市场全无。北京市水产研究所近年来在大连水产学院教授的指导下和市小汤山渔场等单位的协助下,根据轮虫、枝角类等生理生态特性,刺激其休眠卵的大量萌发,在此基础上选用人工饵料、药物处理等技术,培养出大量系
Rotifers, angular classes, copepods, live fish food is ready-made live bait, because it contains a large number of vitamins, enzymes, trace elements and other active substances, as well as high protein content, amino acid ratio is extremely reasonable, is any commodity feed can not Compare. However, the obvious shortcoming is that the instability of natural production can not be supplied in large quantities when needed, and there is no market at all. In recent years, under the guidance of professors from Dalian Fisheries College and assisted by units such as Xiaotangshan Fishery, Beijing Institute of Fisheries has stimulated the massive germination of dormant eggs according to the physiological and ecological characteristics of rotifers and cladocerans Selection of artificial food, drug treatment and other techniques to develop a large number of lines
