摘　　要：本试验利用西泉眼水库岸边静水池塘养殖开口进食已两周的小体鲟幼鱼,其体质量和体长分别为0.125±0.95g、2.98±1.72cm;经过4周饲喂,其育成率达到70%以上;体长为6±2.98cm、体质量1.78±1.25g;体长、体质量增长分别为0.115cm/d、0.0595g/d。试验结果证实如配合采用调整养殖密度、配套养殖设施、清理天敌并在池塘周围建围栏、调节水质、越冬并搭配不同食性、不同水层的鱼种等措施,小体鲟是适于在北方静水池塘生长的。Sterlet （Acipenser ruthenus） frys to take food two weeks ago ,whose body weight and body length were 0.125±0.95g,2.98±1.72 cm ,had been cultured in a stagnant pool besides Xi-quan-yan water reservior. Their body weight and body length attained 6±2.98cm, 1.78±1.25g after four weeks.The survival rate exceed above 70%. Dayly increasing rate of its body length and body weigh was respectively 0.115cm, 0.0595g. By aquacuhural measures,including adjusting culture dense,acompanying facilities, putting up pens around poll after cleaning up enemies,regulating water qualities, hibemalisation,matching different sater layment and food habits fishes ,ect.A.ruthenus laeves are apt to live in a stagnant poll in northern China.
