根据淡水白鲳的营养需求,提出维生素预混料配方(维生素添加剂)和微量元素预混料配方(矿物质添加剂),与淡水白鲳基础日料配方,构成一套全价性的淡水白鲳用高效饲料配方,研制的饲料在工厂化封闭式内循环水体中单养条件下养殖淡水白鲳成鱼,经过170天的精心饲养管理,饲料系数平均为1.89,其中:102~#添加剂投喂的饲料系数平均为1.70。淡水白鲳平均规格达到873克,平均净产15.8kg/米~2。
According to the nutritional needs of freshwater whitefly, proposed vitamin premix formula (vitamin additives) and trace element premix formula (mineral additives), and freshwater whitefly based on the Japanese formula to form a full price of freshwater pomfret With high-efficiency feed formula, the developed feed was cultivated under single-culture conditions in a factory-enclosed closed-loop water body and the freshwater pomfret was cultured for 170 days. The feed coefficient averaged 1.89, of which 102 ~ # The average feed coefficient is 1.70. The average size of freshwater whitefruit reached 873g, with an average net output of 15.8kg / m ~ 2.
