摘　　要：本试验对匙吻鲟的孵化及仔幼鱼培育时期的生活习性及养殖技术进行了初步研究。匙吻鲟鱼苗孵出后经 6d培育 ,开口摄食 ,再经 35d培育 ,全长可达 1 0 0mm。在养殖过程中匙吻鲟均游动在水体中上层 ,易自残。主要摄食轮虫和枝角类 ,对水蚯蚓和人工配合饲料不喜食。匙吻鲟对水质的要求比较高且不耐低氧。The hatching of eye egg and habit at period of fry living were studied After 6 weeks of hatching,fry began to ingestion,then after 35 days,its body length was 100mm.At the process of cultivation,Polyodonitidae altered at the middle and superior of water,and often self-mutilated.The eccentric and angiogram were the main food for them,they did not like to eat water earthworm and diet.Polyodonitidate can not bear the low level of water oxygen and demand high quality water.
