摘　　要：以匙吻鲟(Polyodon spathula)为对象,比较3d饥饿组和对照组(鲜样)匙吻鲟背部肌肉、腹部肌肉、尾部肌肉、皮和头部主要营养成分的变化。结果表明,匙吻鲟经3d饥饿后,背部肌肉和腹部肌肉的水分含量下降明显(P<0.05),表皮的水分含量明显上升(P<0.05),头部和尾部肌肉的水分含量变化不明显;除尾部肌肉的蛋白质含量明显下降和表皮的蛋白质明显上升外(P<0.05),其他部位变化不大;各部位的脂肪含量没有明显的变化;除表皮和总肌肉的总糖含量下降明显外,其他部位变化不明显。Main nutrients of paddlefish（Polyodon spathula）in back muscle,abdominal muscle,tail muscle,skin and head at pre and post 3 days starvation were compared to investigate the nutrient changes between starvated and control（fresh muscle）.Results showed that the moisture content of back muscle and abdominal muscle decreased significantly（P0.05）,and moisture content of skin increased significantly（P0.05）,while moisture content of head muscle and tail muscle did not change significantly after starvation.Tail muscle indicated an decrease and skin manifested an increase in protein content after starvation,the other parts showed no significant changes between starvated and control.The fat content of all parts were not significantly different after starvation.Total sugar content of skin and total muscle decreased significantly（P0.05）,the other parts of paddlefish did not change significantly after starvation.
