为预防和治疗大马哈鱼苗脊柱侧凸症,日本水产厅养殖研究所在饵料中添加0.1、1、10、100毫克/100克饵料5—羟基—L—色氨酸进行投饵试验。试验发现:投喂5—羟基—L—色氨酸添加量低于10毫克/100克饵料的鱼4周后患脊柱侧凸症的约占62%—65%。5—羟基—L—色氨酸添加量增加至100毫克/100克饵料时患脊柱侧凸症的鱼降至1.7%。试验结果表明:大马哈鱼苗饵料 For the prevention and treatment of salmon scoliosis, the Japan Aquaculture Agency Aquaculture Research Institute added bait 5-hydroxy-L-tryptophan to the bait to carry out bait test. The test found that: feeding 5-hydroxy-L-tryptophan addition of less than 10 mg / 100 g bait fish 4 weeks after suffering from scoliosis accounted for about 62% -65%. Fish with scoliosis decreased to 1.7% when the addition of 5-hydroxy-L-tryptophan was increased to 100 mg / 100 g diet. Test results show that: salmon bait material
