Three feeding studies on the vitamin C requirements of channel catfish were conducted with practical and semipurified diets. In a long-duration study in which fish achieved almost a 4,000% increase in weight, 50 mg of l-ascorbic acid/kg diet was required for maximal growth and food efficiency. A diet stability study revealed that excessive losses in activity of l-ascorbic acid occurred when practical diets were stored for 16 weeks at 20 degrees. The typical scoliosis condition associated with severe vitamin C deficiency in fish occurred in the nonsupplemented groups in the study with practical diets. Severe growth reductions were obtained from fish fed nonsupplemented semi-purified diets, yet no incidences of spinal abnormalities were noted.
利用实用饲料和半纯化饲料对斑点叉尾鮰的维生素C需求量进行了三项饲养研究。在一项长期研究中，鱼的体重增长了近4000%，最大生长和饲料效率需要每千克饲料添加50毫克L-抗坏血酸。一项饲料稳定性研究表明，实用饲料在20摄氏度下储存16周时，L-抗坏血酸的活性会过度损失。在实用饲料研究中，未添加维生素C的组出现了与鱼类严重维生素C缺乏相关的典型脊柱侧弯情况。饲喂未添加维生素C的半纯化饲料的鱼生长严重减缓，但未发现脊柱异常情况。
