摘要
对西伯利亚鲟鱼在我国西部甘肃省酒泉市海马泉的驯养及生物学特性进行研究.平均体长220 mm、平均体重25 g的西伯利亚鲟鱼经180 d培育后,平均体长达到547 mm,日均增长1.79 mm,瞬时增长率平均0.498%;水温在16.7～24.7 ℃时,瞬时增长率保持在0.8%以上,水温19.9 ℃时,瞬时增长率为最高1.462%;平均体重达649 g,日均增重3.49 g,瞬时增重率平均1.81%;水温在16.7～24.7 ℃时,瞬时增重率保持在3%以上,水温20.6 ℃时,瞬时增重率为最高4.51%.拟合1龄西伯利亚鲟鱼体长与体重的关系为:W=0.000 4 L3.5936 (r2=0.998) 其中b大于3,为异速生长,说明西伯利亚1龄鲟鱼体重增长快于体长增长.
Studies on the domestication and its biology of Acipenser baeri to Haima spring in Gansu province of western China were conducted. After 180days culture, 547 mm in average length, 1.79 mm daily length gain, 0.498% in instantaneous growth rate（IGRL）, were obtained. IGRL was maintained higher than 0.8% when the water temperature were from 16.7 to 24.7 ℃, highest at 19.9 ℃（1.462%）. For the weight, 649 g in average weight, 3.49 g in daily weight gain, 1.81% in instantaneous growth rate（IGRw）. IGRw was maintained higher than 3 % when the water temperature were from 16.7 to 24.7 ℃, highest at 20.6 ℃ （4.51% ）. The body weighttotal length correlation equations of juvenile Acipenser baer/ was W = 0.000 4 L^3.593 6（12 = 0.998） （b 〉 3）, that is to say the growth character of 1-year-old Acipenser baer/was that the growth of weight was faster than that of length.
